Diana : Really? Anjas : Diana, do you know that plants make their own food? Anjas : Yeah. The process of plants making their food is called photosynthesis. Diana : What do the plants need to make their food? Anjas : To make food, the plants need carbon dioxide, water, and sunlight. Diana : How does photosynthesis happen? Anjas : Photosynthesis happens in the leaves of plants. This is because plants' leaves have pores called stomata that absorb carbon dioxide and green chemical chlorophyll that absorbs sunlight. The sunlight changes into energy that splits water molecules from the roots into hydrogen and oxygen. Oxygen is released into the atmosphere, while hydrogen combines with carbon dioxide form glucose or food for plants. Diana : Then what are the functions of glucose for plants? Anjas : Glucose provides energy for plants' growth and development. 1. What materials are needed for photosynthesis? 2. What is stomata and its function? 3. What is the function of chlorophyll? 4. What is the function of sunlight for photosynthesis? 5. What is the function of glucose for plant?
