Question

What are pigment systems ? Where are they located ?

Answer 1

Pigment systems are a group of photosynthetic pigments found in the chloroplast of a plant. These contain two types of parts i.e. the central core, that converts light energy into chemical energy and is always a type of chlorophyll pigment, and the light harvesting complex ,that absorbs the light from sun and transfers it to the central core and these include caretenoids and xanthophyll also. Based on the pigment at the pigment on the central core there are two types of pigment systems (PS) the PS-1 with P${}_{700}$ as the central core and the other PS-2 with P${}_{680}$ as the central core.
