Biology Class 8 ICSE FAQs

1. What is the significance of photosynthesis in plants?

Ans. Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. It occurs mainly in the chloroplasts of plant cells using chlorophyll. This process not only provides food for the plants themselves but also releases oxygen, which is essential for the survival of most life forms on Earth.

2. What are the main components required for photosynthesis?

Ans. The main components required for photosynthesis are sunlight, carbon dioxide (from the air), and water (from the soil). Sunlight provides the energy needed for the process, while carbon dioxide and water are the raw materials that are transformed into glucose and oxygen.

3. How do plants obtain carbon dioxide for photosynthesis?

Ans. Plants obtain carbon dioxide through small openings in their leaves called stomata. These stomata allow carbon dioxide from the air to enter the leaf, where it is then used in the process of photosynthesis.

4. What is the role of chlorophyll in photosynthesis?

Ans. Chlorophyll is a green pigment found in the chloroplasts of plant cells. It plays a crucial role in photosynthesis by absorbing light energy, primarily from the sun. This energy is then used to convert carbon dioxide and water into glucose and oxygen.

5. What is the equation for photosynthesis?

Ans. The general equation for photosynthesis can be represented as: \[ 6CO_2 + 6H_2O + light \ energy \rightarrow C_6H_{12}O_6 + 6O_2 \] This equation shows that six molecules of carbon dioxide and six molecules of water, using light energy, produce one molecule of glucose and six molecules of oxygen.

6. Why is oxygen important for living organisms?

Ans. Oxygen is crucial for most living organisms as it is required for cellular respiration, a process that converts glucose into energy. This energy is essential for growth, maintenance, and various biological functions. Without oxygen, aerobic organisms would not be able to survive.

7. What factors affect the rate of photosynthesis?

Ans. The rate of photosynthesis can be affected by several factors, including light intensity, carbon dioxide concentration, temperature, and the availability of water. Each of these factors can influence how efficiently a plant can perform photosynthesis.

8. How does light intensity influence photosynthesis?

Ans. Light intensity directly impacts the rate of photosynthesis. At low light levels, the rate of photosynthesis increases with light intensity. However, once a certain level of light intensity is reached, the rate will plateau as other factors become limiting.

9. What is the importance of water in photosynthesis?

Ans. Water is essential for photosynthesis as it is one of the raw materials used in the process. It provides the electrons needed for the light-dependent reactions and contributes to the formation of glucose. Additionally, water helps maintain plant turgor, which is important for their structure.

10. Can photosynthesis occur at night?

Ans. No, photosynthesis cannot occur at night because it requires sunlight to provide the energy needed for the process. However, plants can perform respiration at night, using the glucose produced during the day for energy.

11. What is the difference between photosynthesis and respiration?

Ans. Photosynthesis is the process by which plants convert light energy into chemical energy (glucose) using carbon dioxide and water, releasing oxygen as a byproduct. Respiration, on the other hand, is the process where organisms, including plants, convert glucose and oxygen into carbon dioxide and water, releasing energy for cellular activities.

12. What are the two stages of photosynthesis?

Ans. Photosynthesis consists of two main stages: the light-dependent reactions and the light-independent reactions (Calvin cycle). The light-dependent reactions occur in the thylakoid membranes of the chloroplasts and require sunlight to produce ATP and NADPH. The Calvin cycle takes place in the stroma and uses ATP and NADPH to convert carbon dioxide into glucose.

13. How do environmental changes affect photosynthesis?

Ans. Environmental changes such as temperature fluctuations, changes in humidity, and variations in light conditions can significantly impact photosynthesis. For example, high temperatures can lead to the denaturation of enzymes involved in the process, while low temperatures may slow down the reactions.

14. What adaptations do plants have for efficient photosynthesis?

Ans. Plants have several adaptations for efficient photosynthesis, including broad leaves to capture more sunlight, a waxy cuticle to reduce water loss, and a network of veins to transport water and nutrients. Additionally, some plants have specialized structures like stomata that can open and close to regulate gas exchange.

15. How does deforestation impact photosynthesis and the environment?

Ans. Deforestation reduces the number of trees and plants available for photosynthesis, leading to decreased oxygen production and increased carbon dioxide levels in the atmosphere. This imbalance can contribute to climate change and negatively affect biodiversity, as many species depend on forests for their habitat and food.
