Photosynthetic Pigments

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

Chloroplasts

Organelles found in plant and algae cells where photosynthesis takes place, converting light energy into chemical energy.

Cyclic Electron Transport

A process in photosynthesis where electrons are recycled around the photosystem I, contributing to the production of ATP without the production of NADPH.

Noncyclic Electron Transport

A pathway of photosynthesis where electrons are transported from water to NADP+, producing oxygen and contributing to the generation of ATP.
