Photosynthesis is the process by which plants use sunlight, carbon dioxide and water to produce oxygen and glucose, which provides energy and food for the plant's growth. It occurs in leaves, and requires light, carbon dioxide and water. Photosynthesis produces oxygen that humans and other animals breathe and glucose that is stored in plants and provides their energy and food.
5. What is needed for photosynthesis to occur? Light is needed for photosynthesis to occur. The plant’s leaves use the light to make a sugar called glucose.
6. Why do plants need glucose? Glucose is the food for the plant. It gives the plant energy to grow.
7. How much glucose does a plant make? Plants make enough glucose to be used during the night and on cloudy days when they don’t get sunlight. The extra glucose is stored in the plant’s leaves and other parts.
8. How does photosynthesis help us? During the process of photosynthesis, oxygen is produced. We use this oxygen to breathe.
