FAQs on Quick Revision: How do plants make their food? Video Lecture - Science for Class 4

1. How do plants make their food?
Ans. Plants make their food through a process called photosynthesis. They use sunlight, water, and carbon dioxide to produce glucose and oxygen.
2. What is the role of chlorophyll in the process of making plant food?
Ans. Chlorophyll is a green pigment in plant cells that absorbs sunlight. It is essential for photosynthesis as it helps plants convert light energy into chemical energy to make food.
3. Can plants make food without sunlight?
Ans. No, plants require sunlight for photosynthesis to occur. Without sunlight, they are unable to produce food and may not survive.
4. Why is water important for plants to make food?
Ans. Water is a crucial component in photosynthesis as it provides the hydrogen atoms needed to combine with carbon dioxide to produce glucose. It also helps transport nutrients within the plant.
5. What happens to the oxygen produced during photosynthesis?
Ans. The oxygen produced during photosynthesis is released into the atmosphere as a byproduct. It is essential for the survival of living organisms that depend on oxygen for respiration.
