photosystems
Solar energy converters
Photosystems are protein complexes in plant cells that capture light energy during photosynthesis.
Located in chloroplast membranes, they contain chlorophyll and other pigments that absorb light and convert it to chemical energy.
Plants have two types—photosystem I and photosystem II—which work in sequence to split water molecules and produce the energy carriers that power sugar synthesis.
