Which photosynthetic pigment is found in bacteria but is lacking in all other photosynthetic organisms?
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.
What else can I help you with?
Photosynthetic organisms are usually?
Green plants, algae, and some species of bacteria are examples of photosynthetic organisms. They contain chlorophyll, a pigment that enables them to convert sunlight into energy through the process of photosynthesis. These organisms play a crucial role in the Earth's ecosystems by producing oxygen and serving as a primary source of food for many other organisms.
Do animals have photosynthetic pigment?
No, animals do not have photosynthetic pigments. Photosynthetic pigments, like chlorophyll, are found in plants, algae, and some bacteria, where they absorb sunlight to convert carbon dioxide and water into energy-rich molecules. Animals do not have this capability and instead obtain energy by consuming other organisms.
The primary light-gathering pigment in photosynthetic bacteria and plants is what?
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.
What is the name of the light-sensitive pigment found in photosynthetic archaea?
The light-sensitive pigment found in photosynthetic archaea is called bacteriorhodopsin. It is a type of retinal protein that helps these organisms convert light energy into chemical energy for photosynthesis.
Photosynthetic pigment in bacteria is located in the?
Photosynthetic pigments in bacteria are primarily located in the thylakoid membranes, which are structures embedded in the cytoplasmic membrane. In some bacteria, such as cyanobacteria, these pigments include chlorophyll and carotenoids, which facilitate the capture of light energy for photosynthesis. In other photosynthetic bacteria, such as purple and green sulfur bacteria, different types of bacteriochlorophyll are used. These pigments enable the bacteria to harness light energy and convert it into chemical energy.
What is the principal pigment in photosynthetic organisms?
Chlorophyll is the principal pigment in photosynthetic organisms that absorbs light energy for photosynthesis.
The color of photosynthetic bacteria is?
different colors depending on their pigment
What is a bacteriochlorophyll?
A bacteriochlorophyll is a photosynthetic pigment occurring in various phototrophic bacteria.
What types of organisms use photosynthesis?
Plants, algae, and some types of bacteria are examples of organisms that use photosynthesis to convert sunlight into energy. They contain chlorophyll, a pigment that absorbs light energy and initiates the process of photosynthesis.

What organisms undergo photonthesis?
Plants, algae, and certain bacteria are organisms that undergo photosynthesis. They contain chlorophyll, a pigment that enables them to convert sunlight into energy through the process of photosynthesis.
What do all photosynthetic organisms have in common?
All photosynthetic organisms have chlorophyll or a similar pigment that captures light energy, allowing them to convert carbon dioxide and water into glucose and oxygen. They also have specialized structures, such as chloroplasts, where photosynthesis takes place. Additionally, they require sunlight to power the photosynthetic process.
