FAQs on Printable Worksksheet: Hoe Do Plants make Their Food? - Science for Class 4

1. How do plants make their food through photosynthesis?
Ans.Plants make their food through a process called photosynthesis, where they use sunlight, carbon dioxide from the air, and water from the soil to create glucose (a type of sugar) and oxygen. During this process, chlorophyll in the leaves captures sunlight, which provides the energy needed for the chemical reactions to occur.
2. What is the role of chlorophyll in photosynthesis?
Ans.Chlorophyll is a green pigment found in the chloroplasts of plant cells. Its primary role in photosynthesis is to absorb sunlight, which is essential for converting carbon dioxide and water into glucose and oxygen. Chlorophyll primarily absorbs light in the blue and red wavelengths and reflects green light, giving plants their characteristic color.
3. Why do plants need sunlight for photosynthesis?
Ans.Plants need sunlight for photosynthesis because it provides the energy required to drive the chemical reactions that convert carbon dioxide and water into glucose. Without sunlight, these reactions cannot occur efficiently, and plants would be unable to produce the food they need to grow and thrive.
4. Can photosynthesis occur without sunlight?
Ans.No, photosynthesis cannot occur without sunlight. Sunlight is crucial as it provides the energy necessary for the process. However, some plants can survive in low-light conditions by using stored energy or by adapting their photosynthesis process, but they still require some light to carry out photosynthesis effectively.
5. What are the byproducts of photosynthesis?
Ans.The main byproducts of photosynthesis are glucose and oxygen. Glucose serves as energy and a building block for growth in plants, while oxygen is released into the atmosphere as a waste product, which is essential for the survival of most living organisms on Earth.
