Photosynthesis

Chlorophyll is the main photosynthetic pigment in plants that absorbs light energy, giving leaves their green colour.

Plants exchange gases with the atmosphere mainly through tiny pores called stomata on their leaves, which open and close to control gas flow.

Photosynthesis is powered by light — the more light a plant receives, the faster it can photosynthesise, up to a maximum rate. Light intensity is one of several factors that can limit how quickly photosynthesis occurs.

Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to make glucose and oxygen.
