Chloroplast

... space or lumen. The photosynthesis reaction takes place on the surface of the thylakoid. The photosynthetic proteins in the membrane bind chlorophyll , which is present with various accessory pigments . These give chloroplasts their green colour. Algal chloroplasts may be golden, brown, or red ...

Eukaryote

... DNA and developed from endosymbiotes, in this case cyanobacteria . They usually take the form of chloroplasts , which like cyanobacteria contain chlorophyll and produce energy through photosynthesis . Others are involved in storing food. Although plastids likely had a single origin, not all ...

Lichen

The algal cells contain chlorophyll , permitting them to live in a purely mineral environment by producing their own organic compounds (see photosynthesis ). The fungus protects the ...

Photolysis

... light . Photolysis is a part of photosynthesis , which occurs in the granum of the chloroplast . In photolysis the light absorbed by the chlorophyll is turned into chemical energy which is used to split water into hydrogen and oxygen . The oxygen is released as a byproduct while the hydrogen ...

Thylakoid

... A thylakoid is part of an internal membrane system of chloroplasts folded repeatedly into a stack of disks called grana . It contains chlorophyll , which power the formation of NADPH from NADP+ and H+, and enzymes required to form ATP , NADPH, or both in photosynthesis. The stacks connect by ...
