All questions of Living Creatures: Exploring their Characteristics for Class 6 Exam

The larva stage in the life cycle of a mosquito is aquatic and feeds on organic matter.

Understanding Germination
Germination is the key process by which a seed transforms into a new plant. It marks the beginning of a plant's life cycle and is crucial for the propagation of plant species.
Stages of Germination
- Seed Dormancy: Before germination, seeds are often in a dormant state. They require specific conditions such as moisture, temperature, and sometimes light to initiate the process.
- Water Absorption: The seed absorbs water through a process called imbibition. This hydration activates enzymes that trigger metabolic processes.
- Growth Initiation: Once hydrated, the seed's embryo begins to grow. The radicle (embryonic root) emerges first, anchoring the plant and absorbing nutrients from the soil.
- Shoot Emergence: Following the root, the shoot (plumule) breaks through the soil surface. This leads to the development of leaves, which will start photosynthesis.
Conditions for Germination
- Moisture: Adequate water is essential for activating the seed's metabolic processes.
- Temperature: Different seeds have specific temperature ranges that favor germination. Most seeds germinate best in warm conditions.
- Oxygen: Seeds require oxygen for respiration, which is necessary to produce energy for growth.
Importance of Germination
- Plant Growth: Successful germination leads to the establishment of new plants, contributing to biodiversity and ecosystem stability.
- Agriculture: Understanding germination is crucial for farmers and gardeners to ensure healthy crop production.
In summary, germination is a vital biological process that leads to the formation of new plants from seeds, ensuring the continuation of plant life and contributing to the environment.

Reproduction is the biological process by which new individuals of the same species are produced.

A sunflower turning its head to face the sun (phototropism) is an example of movement in plants.

Sweating to remove excess salts is an example of excretion in humans.

Nutrition is the process by which living beings obtain and use food for their growth, energy, and maintenance.

The froglet stage is when a frog develops legs and lungs, transitioning from an aquatic to a terrestrial environment.

Respiration is the process by which living beings exchange gases with their environment, taking in oxygen and releasing carbon dioxide.

A rock is an example of a non-living thing as it does not exhibit characteristics of life such as growth, respiration, or reproduction.
