FAQs on Class 4 Science - How Do Plants Make Their Food - CBSE Worksheets - 1

1. How do plants make their food?
Ans. Plants make their food through a process called photosynthesis, where they use sunlight, water, and carbon dioxide to produce glucose (sugar) and oxygen.
2. What is the role of chlorophyll in the process of making food in plants?
Ans. Chlorophyll is a green pigment present in the chloroplasts of plant cells. It absorbs sunlight and is essential for photosynthesis, as it helps in converting light energy into chemical energy for the synthesis of food.
3. Can plants make food at night?
Ans. Plants cannot make food at night because photosynthesis requires sunlight. During the night, plants rely on the stored food reserves produced during the day through photosynthesis.
4. Why is water important for plants in making food?
Ans. Water is crucial for plants in making food because it serves as a source of hydrogen atoms needed to produce glucose during photosynthesis. Water is also essential for the transport of nutrients and maintaining turgidity in plant cells.
5. How do plants obtain carbon dioxide for photosynthesis?
Ans. Plants obtain carbon dioxide for photosynthesis through tiny pores called stomata present on their leaves. Carbon dioxide enters the leaves through these openings and combines with water and sunlight to produce glucose and oxygen.
