Photosynthetic pigments are organized into clusters called:

Explanation

The correct answer is photosystems. Photosynthetic pigments are organized into clusters known as photosystems, which are crucial for the efficient absorption and conversion of light energy into chemical energy during photosynthesis. Photosystems are located in the thylakoid membranes and include Photosystem I (PSI) and Photosystem II (PSII), both of which play integral roles in the light-dependent reactions of photosynthesis.Other options like antenna pigments, reaction center, and photosynthetic system refer to components or broader aspects of the photosynthetic process but do not specifically denote the clusters of pigments.
