Photosynthetic cells are quite diverse and include cells found in green plants, phytoplankton, and cyanobacteria. During the process of photosynthesis, cells use carbon dioxide and energy from the ...

Chlorophyll is a green pigment, present in all green plants and in cyanobacteria responsible for the absorption of light to provide energy for photosynthesis.

Photosynthetic organisms collect this light using pigments, like chlorophyll, that are optimized to gather light in the visible range. In a thick mat of cyanobacteria, the cells near the surface ...
