Where are Cyanophyceae found?
Where are Cyanophyceae found?
Cyanobacteria, also called blue-green algae, are microscopic organisms found naturally in all types of water. These single-celled organisms live in fresh, brackish (combined salt and fresh water), and marine water.
Which pigment is present in Cyanophyceae?
Cyanobacteria contain only one form of chlorophyll, chlorophyll a, a green pigment.
Where are cyanobacteria pigments located?
The photosynthetic apparatus of cyanobacteria is located on folded internal membranes, the thylakoid membrane. The machinery consists of two photosystems (PSs) with Chls as the primary light-harvesting pigments and additional pigments located in specialised light-harvesting complexes—the phycobilisomes (PBSs) .
Where is Chlorophyceae found?
The members of Chlorophyceae generally grow in fresh water (about 90%) and the rest in saline water, terrestrial habitat etc. The fresh water members such as Volvox, Oedogonium, Spirogyra etc. grow in ponds, pools and lakes.
Which algae is known as Cyanophyceae?
The term microalgae, in applied phycology, usually includes the microscopic algae and the photosynthetic bacteria (i.e., cyanobacteria), formerly known as Cyanophyceae.
Are cyanobacteria archaea?
THE THREE TYPES OF BACTERIA There are three divisions of the bacteria family. Archaebacteria or “ancient” bacteria, Cyanobacteria or “blue-green” bacteria, Eubacteria or “true” bacteria. Cyanobacteria and Eubacteria are very closely related.
Is cyanobacteria and Cyanophyceae same?
Based on prokaryotic cell structure like bacteria, Christensen (1962) placed both Cyanophyta and bacteria under a common phylum Prokaryota. Cyanophyta or blue green algae have also been named as cyanobacteria.
Where is chlorophyll found in cyanobacteria?
Chlorophyll (also chlorophyl) is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants.
What are the pigments found in Chlorophyceae?
The Chlorophyceae contain chlorophyll a and b, zeaxanthin and lutein, together with a minor proportion of less typical carotenoids.
Which chlorophyll is present in Chlorophyceae?
The Chlorophyceae are one of the classes of green algae, distinguished mainly on the basis of ultrastructural morphology. They are usually green due to the dominance of pigments chlorophyll a and chlorophyll b.
Why is Cyanophyceae called cyanobacteria?
What are Cyanobacteria? Cyanobacteria, formerly known as blue-green algae, are photosynthetic microscopic organisms that are technically bacteria. They were originally called blue-green algae because dense growths often turn the water green, blue-green or brownish-green.
How many species of Cyanophyceae are there in India?
Introduction to Cyanophyceae: It is a primitive group of algae, consists of 150 genera and about 2,500 species. In India, the division is represented by 98 genera and about 833 species. Members of the class Myxophyceae (Cyanophyceae) are commonly known as blue green algae.
What is the mode of reproduction of Cyanophyceae?
The blue green algae (Cyanophyceae) reproduce by both vegetative and asexual means. Sexual reproduction is absent.
What are the principal pigments of chlorophyll?
The principal pigments are chlorophylls a (green), c-phycocyanin (blue) and c-phyco- erythrin (red). In addition, other pigments like β-carotene and different xanthophylls like myxoxanthin and myxoxanthophyll are also present.
What are the pigments found in the chromoplasm?
The pigments are found in the chromoplasm (peripheral) part. Pigments found are chlorophyll a, phycocyanin-r, phycocyanin-c, phycoerytherin-c, β-carotene and as many as eight Xanthophylls. Reserve food material is a glycogen like substance along with some oil drops. Mitochondria, endoplasmic reticulum and Golgi bodies are also absent.
