Chlorophyll

Chlorophyll

  • Chlorophyll is a green pigment found inside plant cell chloroplasts

    • It is this pigment which gives plants their characteristic green colour

  • Chlorophyll absorbs light energy, transferring it into stored chemical energy in the bonds of glucose molecules

  • The glucose produced during photosynthesis can be converted into other carbohydrates, such as sucrose and starch
