The joining of a sperm and an egg during sexual reproduction is called fertilization.

Explanation:

Fertilization is a crucial step in sexual reproduction. It is the process by which a sperm cell from a male combines with an egg cell from a female to form a new individual. This process can occur in plants as well as animals.

Process of Fertilization:

1. Sexual Reproduction: Sexual reproduction involves the fusion of male and female gametes (reproductive cells) to create offspring. In animals, the male gamete is the sperm cell, while the female gamete is the egg cell. In plants, the male gamete is contained in pollen, and the female gamete is present in the ovule.

2. Transfer of Gametes: In animals, the male deposits sperm into the female reproductive system during sexual intercourse. In plants, pollen is transferred from the male reproductive organ (stamen) to the female reproductive organ (pistil) through various means like wind, insects, or other animals.

3. Fusion of Sperm and Egg: Once the sperm reaches the egg, it penetrates the egg's protective layers and fuses with its nucleus. This fusion combines the genetic material from both parents, resulting in a zygote.

4. Zygote Formation: The zygote is the first cell of the new individual. It contains the complete set of chromosomes, half from the mother and half from the father. The zygote divides and develops into an embryo, which eventually grows into a new organism.

Significance of Fertilization:

Fertilization is essential for the continuation of a species. It ensures genetic diversity by combining the genetic material from two parents, resulting in offspring with unique characteristics. Fertilization also allows for the transfer of genetic traits and adaptations, which contribute to the survival and evolution of a species.

In conclusion, fertilization is the process of joining a sperm and an egg during sexual reproduction. It is a vital step in the creation of new individuals and plays a crucial role in genetic diversity and the continuation of species.

Explanation:

Bryophyllum is a succulent plant that belongs to the Kalanchoe genus. It is known for its ability to propagate vegetatively from plantlets that develop on the edges of its leaves.

From which part of the plant does Bryophyllum grow?
- Leaves: Bryophyllum grows from the edges of its leaves. The plantlets develop along the margins of the leaves and eventually drop off to form new plants. This unique method of reproduction is known as vegetative propagation.
- Stems: Bryophyllum primarily grows from its leaves rather than its stems. While the stems of the plant play a supportive role in the growth and development of the plant, the leaves are the main site for the formation of new plantlets.
- Roots: Bryophyllum does not primarily grow from its roots. The roots of the plant serve to anchor it in the soil and absorb water and nutrients, but they are not the main site for growth and reproduction.
- None of the above: The correct answer is that Bryophyllum grows from its leaves. This unique method of reproduction allows the plant to produce new individuals rapidly and efficiently.
In conclusion, Bryophyllum grows from the edges of its leaves through vegetative propagation. This method allows the plant to reproduce asexually and produce new plants without the need for seeds.

Source of Food for Tribal People

From Trees:
Tribal people often rely on the resources provided by nature, including various types of fruits, nuts, and roots that can be found in the forests. They gather these foods from trees and plants that grow naturally in their surroundings. These natural resources are an essential part of their diet and provide them with necessary nutrients.

By Hunting Animals:
In addition to gathering food from trees and plants, tribal people also hunt animals for their meat. Hunting is a traditional practice that has been passed down through generations, and it allows them to supplement their diet with protein-rich foods. They often use traditional hunting methods such as bows and arrows to catch animals like deer, rabbits, and birds.

Combination of Both:
Therefore, the tribal people typically get their food from a combination of sources - they gather fruits, nuts, and roots from trees and plants, while also hunting animals for meat. This dual approach to food procurement ensures that they have a diverse and balanced diet that meets their nutritional needs. It also reflects their deep connection to the natural environment and their reliance on its resources for sustenance.

Propagation of Tea Plant

From Cutting:
- Tea plants are commonly propagated from cuttings.
- Cuttings are taken from mature, healthy plants and planted in a suitable growing medium.
- The cuttings develop roots and grow into new tea plants.

From Seeds:
- Although less common, tea plants can also be propagated from seeds.
- Seeds are collected from mature tea plants and sown in a nursery.
- The seeds germinate and seedlings are transplanted into the field.

From Leaves:
- Tea plants cannot be propagated directly from leaves.
- Leaves are harvested for making tea and do not contain the necessary components for propagation.

By Watering the Ground:
- Watering the ground is a necessary step in the propagation process, but it is not the method of propagation itself.
- Adequate watering is essential for the growth and development of tea plants, whether propagated from cuttings or seeds.

The True Statement:
The true statement among the given options is (b) Some plants can grow completely under water.

Explanation:
Plants are an important part of our ecosystem. They are found everywhere, on land, in water, and even on other plants. Some plants are adapted to live completely under water. These plants are called aquatic plants.

Aquatic plants have adapted to living in water by developing special features that help them to survive. They have special leaves that are often thin and feathery, which helps them to absorb nutrients and oxygen from the water. Some aquatic plants also have roots that are specially adapted to living in water. They may have long, thin roots that can reach down into the mud at the bottom of a lake or river, or they may have roots that float freely in the water.

Some examples of aquatic plants include water lilies, lotus, and hydrilla. These plants are found in lakes, ponds, and other bodies of water. They provide food and shelter to a variety of aquatic animals, and they also help to keep the water clean by absorbing excess nutrients and oxygen.

In conclusion, the true statement among the given options is that some plants can grow completely under water. These plants are called aquatic plants, and they have special features that help them to survive in water.

Why do the leaves of trees change color in the fall?
Answer:
The changing colors of leaves in the fall is a natural process that occurs in deciduous trees. The main reason for this phenomenon is the decrease in chlorophyll production, which is responsible for the green color of leaves during spring and summer. The change in color is a result of various factors, including changes in temperature and daylight hours.
Here is a detailed explanation of why the leaves of trees change color in the fall:
1. Decrease in Chlorophyll:
- Chlorophyll is essential for photosynthesis, the process by which plants convert sunlight into energy.
- During fall, trees start to prepare for winter and reduce their energy production.
- As a result, chlorophyll production decreases, leading to a decline in the green color of leaves.
2. Other Pigments:
- As chlorophyll breaks down, other pigments that were previously masked become visible.
- These pigments include carotenoids (responsible for yellow, orange, and brown colors) and anthocyanins (responsible for red and purple colors).
- The combination of these pigments gives rise to the vibrant hues seen in fall foliage.
3. Temperature and Daylight:
- Temperature and daylight hours play a crucial role in triggering the color change.
- As autumn approaches, the days become shorter, and the nights become cooler.
- This change in environmental conditions signals to the trees that it is time to prepare for winter dormancy.
- The decrease in sunlight and cooler temperatures contribute to the breakdown of chlorophyll and the activation of other pigments.
4. Environmental Factors:
- Environmental factors such as soil moisture, nutrient availability, and weather conditions can also influence the intensity and duration of fall colors.
- Drought or stress can cause leaves to change color earlier or drop prematurely.
In conclusion, the changing colors of leaves in the fall occur due to a decrease in chlorophyll production, which unveils other pigments that were previously masked. This process is triggered by changes in temperature, daylight, and various environmental factors. The beautiful array of fall foliage is a remarkable natural phenomenon that marks the transition from summer to winter.

**A) The days become colder**

During the transition from autumn to winter, trees undergo various changes to prepare for the colder months ahead. One of the most significant signals that indicate a tree is preparing for winter is the drop in temperature, resulting in colder days. This change in temperature triggers a series of physiological and structural adaptations in trees to survive the harsh winter conditions.

**Physiological Adaptations:**

1. **Changes in metabolism:** As the days become colder, trees slow down their metabolic processes. This reduction in metabolic activity helps conserve energy and resources during the winter months when sunlight and water availability are limited.

2. **Photosynthesis slows down:** With fewer hours of sunlight, trees reduce their photosynthetic activity. Photosynthesis is the process by which trees convert sunlight, water, and carbon dioxide into energy and oxygen. Slowing down this process allows trees to conserve energy and focus on other winter survival strategies.

**Structural Adaptations:**

1. **Leaf shedding:** Deciduous trees, such as oak, maple, and birch, prepare for winter by shedding their leaves. This process, known as abscission, involves the tree cutting off the flow of nutrients to the leaves and forming a protective layer at the base of the leaf stem. This enables the tree to drop its leaves without losing excessive water and nutrients.

2. **Bark changes:** Trees may exhibit changes in their bark as winter approaches. Some species develop thicker or rougher bark to provide additional insulation and protection against freezing temperatures. Bark can also change color, with some trees developing a reddish or brownish tint during winter.

3. **Bud formation:** Trees form buds during late summer and autumn in preparation for winter. These buds contain embryonic leaves, flowers, or shoots that will grow once the conditions become favorable in spring. Buds are covered with protective scales that provide insulation and prevent the delicate tissues inside from freezing.

In conclusion, while all the options mentioned may have some influence on tree behavior, the most direct and significant signal that a tree is preparing for winter is the drop in temperature, resulting in colder days. This change triggers a range of physiological and structural adaptations in trees to ensure their survival during the harsh winter conditions.

Explanation:
To make soil fertile, farmers add various substances that provide essential nutrients and improve soil quality. The two main substances commonly used are manure and chemical fertilizers.
Manure:
- Manure is organic matter derived from animal waste.
- It is rich in nutrients such as nitrogen, phosphorus, and potassium.
- Manure improves soil structure and water-holding capacity.
- It enhances microbial activity in the soil, promoting nutrient cycling.
Chemical Fertilizers:
- Chemical fertilizers are synthetic substances that contain essential plant nutrients.
- They are formulated to provide specific ratios of nitrogen, phosphorus, and potassium.
- Chemical fertilizers are readily available to plants and can be quickly absorbed.
- They can be tailored to meet the specific nutrient requirements of different crops.
Combining Manure and Chemical Fertilizers:
- Many farmers use a combination of manure and chemical fertilizers to maximize nutrient availability and soil fertility.
- This approach provides a balanced supply of both organic and inorganic nutrients.
- Manure improves soil organic matter content and enhances long-term soil health.
- Chemical fertilizers provide readily available nutrients for immediate plant uptake.
Conclusion:
To make soil fertile, farmers typically add a combination of manure and chemical fertilizers. This approach ensures a balanced supply of nutrients and promotes both short-term and long-term soil health.

Layering as a method of plant propagation

Plant propagation is the process of creating new plants from existing ones. There are different methods of plant propagation including seed propagation, cutting, grafting, budding and layering. In this question, the method used to produce a new plant from the stem of a plant without detaching it from the plant is being asked. The correct answer is option 'B' which is layering.

Layering

Layering is a method of plant propagation in which a stem of a plant is bent and pinned to the ground. The portion of the stem that is in contact with the soil forms roots and a new plant is produced. This method can also be done by covering a portion of the stem with soil while it is still attached to the parent plant. Layering is a natural method of propagation that occurs in some plants like strawberries, blackberries and raspberries.

Advantages of layering

1. Cloning: Layering produces a new plant that is genetically identical to the parent plant. This means that the new plant will have the same desirable traits as the parent plant.

2. Easy and inexpensive: Layering is an easy and inexpensive method of propagation that does not require any special equipment or tools.

3. Faster growth: Layered plants tend to grow faster and are more mature than those grown from seeds.

4. Increased yield: Layering can be used to increase the yield of a plant by producing more plants from a single parent plant.

Conclusion

Layering is a simple and effective method of plant propagation that is easy to do and does not require any special equipment. It is a natural method that can be used to produce new plants that are genetically identical to the parent plant.

The development process of a seed is called germination.
Here is a detailed explanation of the germination process:
1. Imbibition: The seed takes in water, causing it to swell and soften the seed coat.
2. Activation of enzymes: As water enters the seed, it triggers the activation of enzymes that break down stored nutrients in the endosperm or cotyledons.
3. Breakdown of stored nutrients: The stored nutrients, such as starch, proteins, and lipids, are broken down into simpler forms that can be used by the developing seedling.
4. Cell division and elongation: The cells in the embryo begin to divide rapidly, leading to the growth of the radicle (embryonic root) and plumule (embryonic shoot).
5. Emergence of the radicle: The radicle pushes through the seed coat and emerges from the seed, anchoring the seedling into the soil.
6. Development of the shoot: The plumule grows upward, breaking through the soil surface and developing leaves for photosynthesis.
7. Root development: The radicle grows longer and develops lateral roots, allowing the seedling to absorb water and nutrients from the soil.
8. Establishment of photosynthesis: Once the leaves have fully developed, the seedling can carry out photosynthesis to produce its own food.
9. Growth and maturity: The seedling continues to grow and mature into a mature plant, producing flowers and fruits that contain seeds for reproduction.
Germination is a critical stage in the life cycle of a plant as it marks the transition from a dormant seed to an actively growing seedling. It requires the right conditions of moisture, temperature, and oxygen to occur successfully.

**Seed Germination and Water**

When it comes to seed germination, water plays a crucial role. Seeds require water to initiate the germination process, but keeping seeds continuously submerged under water can actually prevent germination. Let's explore why this is the case:

**1. Seed Structure and Dormancy:**
Seeds have a protective outer covering called the seed coat, which helps to maintain dormancy and prevent premature germination. This seed coat is impermeable to water, meaning that water cannot easily penetrate and reach the embryo inside.

**2. Water Absorption:**
For germination to occur, seeds need to absorb water through a process called imbibition. During imbibition, the seed coat becomes permeable to water, allowing it to enter the seed and activate the metabolic processes necessary for germination.

**3. Oxygen Availability:**
Along with water, seeds also require oxygen to break down stored nutrients and convert them into energy for growth. Oxygen is necessary for respiration, which provides energy for the germination process. However, when seeds are submerged under water, the oxygen supply becomes limited, hindering the germination process.

**4. Anaerobic Conditions:**
When seeds are kept under water, they experience anaerobic conditions, meaning the absence of oxygen. In such conditions, the seed may undergo fermentation instead of aerobic respiration. Fermentation is an inefficient process that produces less energy and can lead to the death of the seed before germination can occur.

**5. Lack of Light:**
Seeds also require light for germination. When submerged under water, light cannot reach the seed, and this lack of light can inhibit germination.

**Conclusion:**
Keeping seeds under water prevents germination due to several factors. The impermeable seed coat restricts water absorption, the limited oxygen supply prevents respiration, anaerobic conditions hinder metabolic processes, and the absence of light inhibits germination. Therefore, the correct answer is option 'B': The seeds will not germinate when kept under water.

Introduction:
When a mango sapling grows too close to the parent tree, it can face several challenges that can hinder its growth and development. These challenges include limited space for spreading its branches, insufficient water supply, and inadequate sunlight exposure. Consequently, the correct answer to the question is option 'D' - all of the above.

Explanation:
Let's discuss each of these challenges in detail:

1. Limited space for spreading branches:
When a mango sapling grows too near to the parent tree, it may not have enough space to spread its branches. As the parent tree grows larger, it will occupy more space and create a crowded environment for the sapling. This lack of space can restrict the sapling's ability to grow and spread its branches, resulting in stunted growth.

2. Insufficient water supply:
Since the parent tree is already established and has an extensive root system, it will likely absorb most of the available water in the surrounding soil. As a result, the mango sapling growing nearby may not receive an adequate water supply. Water is essential for the growth and survival of plants as it helps in nutrient absorption, photosynthesis, and maintaining turgidity. Without sufficient water, the sapling may struggle to develop properly and may even wilt or die.

3. Inadequate sunlight exposure:
Mango trees require abundant sunlight to carry out photosynthesis, which is vital for their growth and production of energy. When a sapling grows too close to the parent tree, it may be shaded by the larger tree's canopy. This limited exposure to sunlight can hinder the sapling's ability to photosynthesize effectively, leading to weakened growth and reduced vigor.

Conclusion:
In conclusion, when a mango sapling grows too near to the parent tree, it faces several challenges including limited space for spreading branches, insufficient water supply, and inadequate sunlight exposure. These factors can collectively hamper the sapling's growth and overall health. Therefore, it is essential to ensure proper spacing between mango saplings and parent trees to promote optimal growth and development.

The seed with thick fibrous outer covering is:
Answer: B: Coconut
Explanation:
The seed with a thick fibrous outer covering is the coconut. Here is a detailed explanation:
1. Seed Structure: Seeds are the reproductive structures of plants that contain an embryo, stored food, and a protective outer covering.
2. Seed Coat: The outer covering of a seed is known as the seed coat or testa. It protects the embryo and the endosperm inside.
3. Coconut Seed: The coconut is a large seed with a thick fibrous outer covering, which is the husk or the mesocarp.
4. Husk: The husk of the coconut is made up of tough fibers that surround the inner shell. It is thick and fibrous, providing protection to the inner parts of the seed.
5. Endosperm: Inside the husk, there is a hard inner shell that encloses the endosperm. The endosperm is the nutritive tissue that provides nourishment to the developing embryo.
6. Embryo: The embryo is the developing plant inside the seed. It contains the embryonic shoot (plumule) and the embryonic root (radicle).
7. Coconut Uses: Coconuts are widely used for their water, meat, and oil. The thick fibrous husk also has various uses, such as making ropes, mats, and other natural products.
In conclusion, the coconut has a thick fibrous outer covering, which is the husk or mesocarp. This fibrous husk provides protection to the inner parts of the seed, including the endosperm and the developing embryo.

Stems

Sugarcane is primarily grown from the stem of the plant. Here is why:

Stems:
- Sugarcane is a type of tall grass, and its stem contains the sugar-rich juice that is harvested for various purposes.
- Farmers plant sugarcane by cutting the stems into smaller sections called setts, which are then planted into the soil to grow new plants.
- The stem of the sugarcane plant is where the majority of the growth and sugar production take place, making it the most important part for cultivation.

Roots:
- While roots are essential for the overall health and stability of the plant, sugarcane is not typically grown directly from the roots.
- Instead, the roots support the growth of the stem and help the plant absorb nutrients and water from the soil.

A and B both:
- In some cases, both stems and roots are involved in the propagation of sugarcane plants. The roots provide support and nourishment, while the stems contain the vital sugars for growth and development.
- However, when it comes to the primary source of growth and production, it is the stem of the plant that is most crucial for cultivating sugarcane.

How has deforestation affected wildlife?
Deforestation has had a significant impact on wildlife, leading to various negative consequences. Here are some ways in which deforestation affects wildlife:
Near Extinction of Species:
- Due to deforestation, habitats of many animal species have been destroyed, pushing them to the brink of extinction. Forest-dependent species such as orangutans, tigers, and gorillas are particularly vulnerable.
- The loss of habitat disrupts the natural balance, making it difficult for certain species to find suitable conditions to survive and reproduce.
Lack of Shelter:
- Deforestation removes trees and vegetation that provide animals with essential shelter and protection from predators.
- Without adequate shelter, animals are exposed to harsh weather conditions, making them more susceptible to disease, stress, and death.
- Many species, including birds and mammals, rely on specific types of trees for nesting and breeding, which become scarce with deforestation.
Lack of Food:
- Deforestation leads to the destruction of food sources for wildlife.
- Trees provide fruits, nuts, and seeds that form a significant part of the diet for many animal species.
- With the loss of forested areas, animals struggle to find enough food, leading to malnutrition, decreased reproductive success, and ultimately population decline.
Disruption of Ecosystems:
- Forests play a crucial role in maintaining balanced ecosystems. They provide habitats for countless species and support intricate food webs.
- Deforestation disrupts these ecosystems, affecting the entire web of life, including plants, animals, and microorganisms.
- The loss of biodiversity can have cascading effects, leading to imbalances in populations, reduced resilience to environmental changes, and potential ecosystem collapse.
In conclusion, deforestation has a profound impact on wildlife. It threatens species with extinction, deprives animals of shelter and food, and disrupts crucial ecosystems. Conservation efforts and sustainable land use practices are essential to mitigate these negative effects and preserve biodiversity.

The primary method by which horsetail spores are dispersed is through wind.

Explanation:
Horsetails are primitive plants that reproduce by spores rather than seeds. The spores are small and lightweight, allowing them to be easily carried by the wind to new locations. This method of dispersal is known as anemochory.

Advantages of wind dispersal:
1. Long-distance dispersal: Wind can carry spores over long distances, allowing horsetails to colonize new areas and expand their range.
2. Increased genetic diversity: Wind dispersal helps to mix the genetic material of different individuals, promoting genetic diversity within horsetail populations.
3. Exploitation of different habitats: Wind dispersal enables horsetails to reach and colonize a wide range of habitats, including open fields, forests, and wetlands.

Adaptations for wind dispersal:
1. Lightweight spores: The spores of horsetails are small and lightweight, facilitating their transport by wind currents.
2. Elongated structures: Horsetails have elongated structures called sporangiophores that hold the spores. These structures are arranged in clusters called strobili, which are positioned at the top of the plant for optimal wind exposure.
3. Spore release mechanisms: Horsetails have specialized mechanisms for releasing spores. When the spores are mature, the strobili open up, allowing the wind to disperse the spores.

Other methods of spore dispersal:
While wind dispersal is the primary method for horsetail spores, they can also be dispersed by water or animals to a lesser extent.
- Water: In wet habitats, such as marshes or along river banks, horsetail spores can be carried by water currents to new locations.
- Animals: Though less common, horsetail spores can sometimes hitch a ride on the fur or feathers of animals, allowing them to be transported to different areas.

Overall, wind dispersal is the most effective method for horsetail spores, enabling these primitive plants to colonize various habitats and ensure their survival and reproduction.

Explanation:
The correct answer is C: Radicle.
The embryo is the early stage of development in a plant seed. It consists of several parts, and the radicle is the first part to grow. Here is a breakdown of the different parts of the embryo and their order of growth:
1. Cotyledon: The cotyledon is a structure that stores food for the developing plant. It is not the first part to grow.
2. Plumule: The plumule is the embryonic shoot that will develop into the stem and leaves. It grows after the radicle.
3. Radicle: The radicle is the embryonic root that emerges first from the seed. It is responsible for anchoring the plant and absorbing water and nutrients from the soil. The radicle is the first part of the embryo to grow.
4. Leaves: The leaves are not part of the embryo but develop from the plumule. They are responsible for photosynthesis and usually grow after the radicle and plumule.
In summary, the radicle is the first part of the embryo to grow. It emerges from the seed and develops into the root system of the plant, providing support and nutrient absorption.

The roots of plants absorb both nutrients and water from the soil.


- The roots of plants have tiny hair-like structures called root hairs that increase the surface area of the roots, allowing them to absorb nutrients effectively.
- These nutrients include essential elements like nitrogen, phosphorus, potassium, calcium, magnesium, and many others.
- Plants need these nutrients for their growth, development, and overall health.
- Nutrients are present in the soil in various forms, such as minerals, organic matter, and decomposed plant and animal material.
- The roots absorb these nutrients through the process of active transport, where they selectively take in the required elements.


- Water is crucial for the survival of plants as it plays a vital role in various physiological processes.
- The roots absorb water from the soil through a process called osmosis.
- Osmosis is the movement of water molecules from an area of low solute concentration (in this case, the soil) to an area of high solute concentration (inside the plant roots).
- The roots have a higher concentration of solutes, such as ions and sugars, compared to the soil.
- This concentration gradient allows water to move into the plant roots, providing the necessary hydration.


- The roots of plants act as anchors, holding the plant in place and providing stability.
- They also store nutrients and water for times when they are not readily available in the soil.
- In addition to absorbing nutrients and water, the roots also exchange gases with the soil, taking in oxygen and releasing carbon dioxide.
- The root system of a plant can vary in size and structure depending on the type of plant and its environment.
- Some plants have shallow root systems, while others have deep taproots that can penetrate deep into the soil to access water and nutrients.

In conclusion, the roots of plants play a vital role in absorbing both nutrients and water from the soil. This allows the plants to obtain the necessary resources for their growth, development, and overall health.
