| pyrenoid | <plant biology> Small body found within some chloroplasts, that may contain protein. In green algae may be involved in starch synthesis. (18 Nov 1997) |

| pyrenoid |
In cell biology, pyrenoids are centers of carbon dioxide fixation. They are not membrane-bound organelles, but specialized areas in algal plastids and contain high amounts of ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO). RubisCO takes carbon dioxide and adds it to the sugar ribulose-1,5-bisphosphate. It needs six molecules of carbon dioxide and six molecules of ribulose-1,5-bisphosphate = six cycles of the Calvin cycle to make one new molecule of glucose. ...

Cytoplasmic structure made of protein or appended to the chloroplasts in most phytoflagellates. They are associated with the formation or storage of polysaccharide food reserves (usually starch)(Steidinger & Tangen 1996).
