need help? review these concept resources.

Explanation:

In photosystems, the antenna (or light - harvesting) complex is responsible for containing all the pigment molecules. These pigment molecules function to absorb light energy. The light - harvesting complex (also known as the antenna complex) is a crucial part of the photosystem structure, where multiple pigment molecules are assembled to capture light efficiently.
