What are the functions of leaves?

  • Photosynthesis: This is the most important function of a leaf. They contain chloroplasts which have the pigment chlorophyll that is responsible for helping in photosynthesis.
  • Helps the plant breathe: The epidermis of the leaf contains guard cells that control and regulate the small pores on the undersurface of the leaves. These pores are called stomata. Stomata are responsible for regulating water in and out of the cell. It is also responsible for the exchange of gases across the epidermis.
  • Storage of food: In some plants, the leaves are modified to store food.
