Plants and photosynthesis. Animals eat food to get their energy. But green plants don't. Instead they make their own food, glucose, in a process called photosynthesis. We say that plants can photosynthesise. These are the things that plants need for photosynthesis: carbon dioxide.water. light.lants and photosynthesis. Animals eat food to get their energy.
