Draw a neat and labelled diagram of chloroplast

Draw a neat and labeled diagram of chloroplast. What are accessory pigments? State their functions.

Accessory pigments are pigments other than chlorophyll a which help in the absorption of light.

They help perform the following functions:

  1. Widen the range of light absorbed in the chloroplast.
  2. Absorb light and transfer the energy to chlorophyll a , which is the reaction centre for photosynthesis.
  3. Protect chlorophyll a from photo-oxidation.
