Phycocyanin: En potentiell läkemedel mot cancerbehandling

Usually, the main and most abundant pigment in photosynthesis is chlorophyll which absorbs all the colors of light except green because green is the color that chlorophyll reflects. Chl are primary photosynthetic pigments in plants and other photoautotrophs. The term chlorophyll is derived from the Greek chloros meaning green and phyllon meaning leaf. The characteristic green color of Chl results from its ability to absorb the light in the blue and red regions, whereas Chl attenuates the light in the green region to a much less extent.

The photosynthetic pigments are chlorophyll a, chlorophyll c,β, and c- carotenes and   Phycoerythrin (PE) is a red protein-pigment complex from the light-harvesting phycobiliprotein family, and cryptophytes It is an accessory to the main chlorophyll pigments responsible for photosynthesis.

Gamona,b,c,1, K. Fred Huemmrichd, Christopher Y. S. Wonge,f, Ingo Phytoplankton (phyto, plant; plankton, wandering) are the free-floating microscopic plant cells, which contain photosynthetic pigments found in both terrestrial and marine environments. these populations in photosynthetic pigment concen-trations and light reactions has not been previously characterized. To build upon previous work, we determined the genetic variation across source popu-lations in the concentrations of pigments, F PSII and ETR in relation to the variation in SLA and N. We also sought linkages between leaf photosynthetic bacteria. Other pigments include carotenoids and phycobilins, sometimes referred to as the accessory pigments.

Deras främsta funktion är fotosyntesen, som använder de gröna pigmenten klorofyller tillsammans med flera röda till gula pigment som bidrar till att fånga in så mycket ljus som möjligt. Andra funktioner innefattar att ge färg åt blommor för att locka till sig pollinatorer. Other articles where Polysiphonia is discussed: algae: Annotated classification: Kappaphycus, Palmaria, Polysiphonia, Porphyra, and Rhodymenia. Division Dinoflagellata (Pyrrophyta) Taxonomy is contentious. Predominantly unicellular flagellates; approximately half of the species are heterotrophic rather than photosynthetic; photosynthetic forms with Photosynthetic Pigments. Pigments are colorful compounds.

There are three main types of pigments: chlorophylls (a and b), carotenoids, and phycobilins. They also supplement photosynthetic pigments that absorb light energy in the blue region. Defensive role of pigments [ edit ] It's known that animals use their color patterns to warn off predators, however it has been observed that a sponge pigment mimicked a chemical which involved the regulation of moulting of an amphipod that was known to prey on sponges.

Polysiphonia photosynthetic pigments

photosynthetic pigments of some red seaweeds and different seasons. RESULTS TAXONOMIC DESCRIPTION OF THE TESTED RED SEAWEEDS The five species of Rhodophyta collected from Abu Qir Bay were identified as: Corallina elongata Ellis et Solander, Corallina officinalis Linnaeus, Jania rubens (Linnaeus) Lamouroux, Polysiphonia elongata (Hudson) Sprenge and Cell Structure • Cells of the central and pericentral siphons are long and cylindrical • Cell wall is two layered - outer pectin and polysulphate esters and inner cellulose • Internal to the cell wall is the cell membrane • Cytoplasm forms a lining layer – contains a single nucleus, several discoid chromatophores which contain photosynthetic pigments – Chlorophylls a and d , carotene, xanthophylls, blue Phycocyanin, red Phycoerythrin (Phycobilins) . Some workers believe Polysiphonia is parasitic as it gains sugars from its host via hyphae sunk into egg wracks tissue. Other suggest Polysiphonia would not still have red photosynthetic pigment if it was a true parasite and hence suggest the relationship is epiphytic.
