Function: light-harvesting accessory pigments that transfer energy to chlorophyll- a. There are other compounds e. Chlorophyll can go from a. Their physical arrangement in the macula lutea is believed to be the cause of Haidinger's brushan entoptic phenomenon that enables perception of polarizing light. Size Plankton are also often described in terms of size. Coccolithophorids: single cells with external shell of calcareous plates coccoliths. These enzymatic cycles were found to play a key role in stimulating energy dissipation within light-harvesting antenna proteins by non-photochemical quenching - a mechanism to reduce the amount of energy that reaches the photosynthetic reaction centers.
abundant marine taxa of the coccolithophorids (prym- nesiophyceae complex pigment pattern, including myxoxanthophyll, canthaxanthin and echinenone. A photosynthetic pigment is a pigment that is present in chloroplasts or photosynthetic bacteria Carotene: an orange pigment; Xanthophyll: a yellow pigment; Phaeophytin a: a gray-brown pigment; Phaeophytin b: a yellow-brown pigment.
Xanthophylls (originally phylloxanthins) are yellow pigments that occur widely in nature and proteins by non-photochemical quenching- a mechanism to reduce the amount of energy that reaches the photosynthetic reaction centers.
Xanthophylls are oxygenated derivatives of carotenes.

|Because the animals all the way up the food chain ultimately depend on the supply of phytoplankton at the base, if the plankton disappear, the chain is broken and eventually the animals will suffer.
Both autotrophic and heterotrophic.

Pigments: chlorophyll a; c, ß-caroteneand several xanthophylls. Silicoflagellates: have internal skeleton of silicous spines.

Silicoflagellates are primarily marine mixotrophic (photosynthetic as well as Extensive HPLC pigment analysis of Dictyocha speculum indicates a similarity to a.
Further information: Archaea. The reason that there are so many pigments is that each absorbs light more efficiently in a different part of the electromagnetic spectrum.
