Photosynthetic eukaryotes and cyanobacteria carry out __ photosynthesis, so named because oxygen is generated and released into the environment when light energy is converted to chemical energy. In these phototrophs, the most important pigments are the __. Certain bacteria carry out a second type of photosynthesis called __ photosynthesis. The phototrophic process derives its name from the fact that molecules other than water are used as an electron sources and therefore __ is not produced. These phototrophs have light-absorbing pigments called __. Within the last decade, it has become apparent that many bacteria and archaea are capable of chlorophyll-independent __.
