A photosynthetic pigment (accessory pigment; chloroplast pigment; antenna pigment) is a pigment that is present in chloroplasts or photosynthetic bacteria and captures the light energy necessary for photosynthesis. List of photosynthetic pigments (in order of increasing polarity): Carotene: an orange pigment; Xanthophyll: a yellow pigment
Biological pigments are any coloured material in plant or animal cells. All biological pigments selectively absorb certain wavelengths of light while reflecting others. [28] [29] The primary function of pigments in plants is photosynthesis, which uses the green pigment chlorophyll and several colourful pigments that absorb as much light energy ...
It is commonly called alumina and may also be called aloxide, aloxite, or alundum in various forms and applications. It occurs naturally in its crystalline polymorphic phase α-Al 2 O 3 as the mineral corundum , varieties of which form the precious gemstones ruby and sapphire .
The reaction center is in the thylakoid membrane. It transfers absorbed light energy to a dimer of chlorophyll pigment molecules near the periplasmic (or thylakoid lumen) side of the membrane. This dimer is called a special pair because of its fundamental role in photosynthesis. This special pair is slightly different in PSI and PSII reaction ...
When seen from below by a predator, the bioluminescence helps to match the squid's brightness and color to the sea surface above. Further information: Counterillumination In many animals of the deep sea, including several squid species, bacterial bioluminescence is used for camouflage by counterillumination , in which the animal matches the ...
Prochlorococcus is a genus of very small (0.6 μm) marine cyanobacteria with an unusual pigmentation (chlorophyll a2 and b2).These bacteria belong to the photosynthetic picoplankton and are probably the most abundant photosynthetic organism on Earth.
Camouflage works due to its ability to hide the contour, or outline, of the body, because the human eye has a limited capacity to distinguish color patterns from far away. Image credits: Sasha ...
The brine formed during the melting sea ice creates pores and channels in the sea ice in which these microbes can live. As a result of these gradients and dynamic conditions, a higher abundance of microbes are found in the lower layer of the ice, although some are found in the middle and upper layers.
