FAQs on Photosynthesis Video Lecture - Science & Technology for UPSC CSE

1. What is photosynthesis?
Ans. Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose (a type of sugar) and oxygen. This process is vital for the production of food and oxygen on Earth.
2. How does photosynthesis work?
Ans. Photosynthesis occurs in the chloroplasts of plant cells, where chlorophyll pigments capture sunlight energy. This energy is then used to convert carbon dioxide and water into glucose and oxygen through a series of chemical reactions known as the Calvin cycle.
3. What are the main components required for photosynthesis?
Ans. The main components required for photosynthesis are sunlight, carbon dioxide, and water. Sunlight provides the energy needed for the process, while carbon dioxide and water are the raw materials that are converted into glucose and oxygen.
4. Why is photosynthesis important?
Ans. Photosynthesis is important for several reasons. It is the primary source of oxygen in the atmosphere, which is essential for the survival of all living organisms. Additionally, photosynthesis is responsible for the production of glucose, which serves as the main source of energy for plants and other organisms that consume plants.
5. How does photosynthesis impact the environment?
Ans. Photosynthesis plays a crucial role in maintaining the balance of gases in the atmosphere. It removes carbon dioxide, a greenhouse gas, from the atmosphere and releases oxygen. This helps regulate the Earth's climate and reduce the effects of global warming. Additionally, photosynthesis is the foundation of most food chains, as it provides energy and nutrients for other organisms.
