FAQs on How do Plants Make Their Food? Video Lecture - Science Olympiad Class 4
| 1. How do plants make their food? |  |
Ans. Plants make their food through a process called photosynthesis. They use sunlight, carbon dioxide from the air, and water from the soil to produce glucose (a type of sugar). This process takes place in the chloroplasts, which are present in the leaves of plants.
| 2. What is photosynthesis? | |
Ans. Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen. It occurs in the chloroplasts of plant cells, specifically in the green pigment called chlorophyll. This process is vital for the survival of plants and is responsible for producing oxygen that is essential for all living organisms.
| 3. What are the necessary components for photosynthesis? | |
Ans. The necessary components for photosynthesis are sunlight, carbon dioxide, and water. Sunlight provides the energy needed for the process, while carbon dioxide is obtained from the air through tiny pores called stomata on the leaves. Water is absorbed by the roots from the soil and transported to the leaves through the stem.
| 4. How does sunlight play a role in photosynthesis? | |
Ans. Sunlight plays a crucial role in photosynthesis as it provides the energy required for the process. The chlorophyll in the chloroplasts of plant cells captures the sunlight and converts it into chemical energy. This energy is then used to convert carbon dioxide and water into glucose and oxygen.
| 5. Why is photosynthesis important for plants? | |
Ans. Photosynthesis is essential for plants as it is the process through which they produce their own food. Glucose, the product of photosynthesis, serves as a source of energy for plants and helps in their growth and development. Additionally, photosynthesis also releases oxygen into the atmosphere, which is vital for the survival of all living organisms.
