    Plant systems
Description:
Photosynthesis is the process by which plants make their food using sunlight, water and carbon dioxide. It takes place inside special structures in leaf cells called chloroplasts. The gas exchange involved in photosynthesis is shown in red in this diagram. Water and nutrients are also required for the plant to survive. They are absorbed by the plant's roots, as shown by the blue labels. Water eventually passes out of the plant via its leaves. This is known as transpiration.
