Another important photosynthetic bacterial group-Halobacteria thrive in very salty environments, such as the Dead Sea and the Great Salt Lake. Halobacteria are unique in that they perform photosynthesis without chlorophyll. Instead, their photosynthetic pigments are bacteriorhodopsin and halorhodopsin. These pigments are similar to sensory rhodopsin, the pigment used by humans and other animals for vision. Bacteriorhodopsin and halorhodopsin are embedded in the cell membranes of halobacteria and each pigment consists of retinal, a vitamin-A derivative, bound to a protein. Irradiation of these pigments causes a structural change in their retinal. This is referred to as photoisomerization. Retinal photoisomerization leads to the synthesis of ATP. Halobacteria have two additional rhodopsins, sensory rhodopsin-I and sensory rhodopsin-II. These compounds regulate phototaxis, the directional movement in response to light.
Chlorophyll is the primary pigment in plants. It gives the green color to plants. Its main function is to help in the synthesis of carbohydrates from carbon-di-oxide by the process of photosynthesis.
Accessory pigments are light-absorbing compounds, found in photosynthetic organisms, that work in conjunction with chlorophyll a. They include other forms of this pigment, such as chlorophyll b in green algal and higher plant antennae, while other algae may containchlorophyll c or d.
Chlorophyll a
no only plants have chlorophyll
They are the chlorophyll. They are the main photosynthetic pigment
Chloroplast.
different colors depending on their pigment
A bacteriochlorophyll is a photosynthetic pigment occurring in various phototrophic bacteria.
all green plants and primitive organisms like cyanobacteria do photosynthesis using chlorophyll pigment
That pigment is chlorophyll.
