If you take a look outside, you’ll probably see lots of green. Green grass, green leaves covering trees and green plants, but why are leaves green?
Most plant leaves are green as they contain a pigment called chlorophyll which is green.
Chlorophyll is needed for plants to absorb sunlight which they need to make glucose through a process called photosynthesis.
Photosynthesis takes place in the chloroplasts of a plant cell. It is chloroplasts that contain the green chlorophyll. Chloroplasts are a bit like tiny solar panels making energy from the light of the sun.
