Definitions:

Photosystem I

A component of the chloroplast's thylakoid membrane in plants that is involved in the light-dependent reactions of photosynthesis, specifically known for aiding in the process of converting solar energy into chemical energy.

Reaction Center

The portion of a photosystem that includes chlorophyll a molecules capable of transferring electrons to a primary electron acceptor, which is the first of several electron acceptors in a series. See antenna complex and photosystem.

Antenna Complex

The arrangement of chlorophyll, accessory pigments, and pigment-binding proteins into light-gathering units in the thylakoid membranes of photoautotrophic eukaryotes. See reaction center and photosystem.

Photosynthetic Pigments

Molecules found in plants and other photosynthetic organisms that absorb specific wavelengths of light and convert it into chemical energy.
