What is the function of chromatophores in bacteria?
In some forms of photosynthetic bacteria, a chromatophore is a coloured, membrane-associated vesicle used to perform photosynthesis. They contain different coloured pigments. Chromatophores contain bacteriochlorophyll pigments and carotenoids.
Where are chromatophores found in bacteria?
Bacteria. Chromatophores are also found in membranes of phototrophic bacteria. Used primarly for photosynthesis, they contain bacteriochlorophyll pigments and carotenoids. In purple bacteria, such as Rhodospirillum rubrum the light-harvesting proteins are intrinsic to the chromatophore membranes.
Is chromatophore a Mesosome?
Chromatophore is a pigment bearing cell or structure found in certain fish,reptiles and other animals. Mesosome is a folded invagination in the plasma membrane of bacteria produced by the chemical fixation techniques.
What are chromatophores in prokaryotes?
Complete answer: Chromatophores are internal membrane systems present in photosynthetic prokaryotes and should become extensive and sophisticated in photosynthetic bacteria. These develop as membrane lined sacs or thylakoids from the cell wall.
Is bacteria motile or nonmotile?
Coliform and Streptococci are examples of non-motile bacteria as are Klebsiella pneumoniae, and Yersinia pestis. Motility is one characteristic used in the identification of bacteria and evidence of possessing structures: peritrichous flagella, polar flagella and/or a combination of both.
Is a chromatophore an inclusion body?
Inclusion bodies lying free inside the cells for carrying out various metabolic activities.
Are bacterial cells motile or nonmotile?
In which following the Chromatophore is found?
Chromatophores are organs that are present in the skin of many cephalopods, such as squids, cuttlefish, and octopuses, which contain pigment sacs that become more visible as small radial muscles pull the sac open making the pigment expand under the skin. Electrical activity within a chromatophore nerve (Fig.
What is the difference between Chromatophore and Mesosome?
Chromatophores are the infoldings of plasma membrane containing pigments needed for photosynthesis. They contain pigment known as Bacteriochlorophyll like chloroplast have chlorophyll. Mesosomes are also invagination of plasma membrane and found in bacteria. They are the site for respiration.
What is the meaning of chromatophore?
Medical Definition of chromatophore 1 : a pigment-bearing cell especially : a cell (such as a melanophore) of an animal integument capable of causing integumentary color changes by expanding or contracting. 2 : the organelle of photosynthesis in photosynthetic bacteria (as the cyanobacteria) : chromoplast, chloroplast.
What is motile and nonmotile?
Hii.. Motile means something which can move or has the ability to move.. Non-motile is when a thing is stationary or doesnt hav the ability to move..

How are chromatophores similar to plant mitochondria?
Bacterial chromatophores exhibit certain biochemical properties similar to those of chloroplasts and are comparable to those of plant or animal mitochondria.
