FAQs on Photosynthesis mcq test - Class 7

1. What is photosynthesis?
Ans. Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose (a type of sugar) and oxygen. This process occurs in the chloroplasts of plant cells.
2. What are the raw materials required for photosynthesis?
Ans. The raw materials required for photosynthesis are sunlight, carbon dioxide, and water. Sunlight provides the energy needed for the process, while carbon dioxide and water are used to produce glucose and oxygen.
3. How does photosynthesis benefit plants and the environment?
Ans. Photosynthesis is vital for plants as it allows them to produce their own food (glucose) using sunlight. This food provides energy for growth, reproduction, and other metabolic processes. Additionally, photosynthesis also releases oxygen into the atmosphere, which is essential for supporting life on Earth.
4. How do plants absorb sunlight for photosynthesis?
Ans. Plants absorb sunlight through specialized cell structures called chloroplasts, which contain a green pigment called chlorophyll. Chlorophyll absorbs light energy from the sun and converts it into chemical energy, which is then used for photosynthesis.
5. What are the factors that can affect the rate of photosynthesis?
Ans. Several factors can affect the rate of photosynthesis, including the intensity of sunlight, the availability of carbon dioxide and water, temperature, and the presence of chlorophyll. Any change in these factors can impact the efficiency of photosynthesis.
