Need pigments to absorb visible light: chl a, chl b, carotenoids (carotenes, xanthophylls)
There are two photosystems: PSII and PSI. Each consists of a reaction center containing 2 chl a molecules and an antenna complex of accessory pigments and more chl a. (accessory pigments: chl b, carotenoids [carotenes and xanthophylls]) The photosystems are connected to each other via a chain of electron carrier molecules
