What are blue-green bacteria called?
Cyanobacteria
Blue-green algae are actually types of bacteria known as Cyanobacteria.
What are features of blue-green bacteria?
Blue-green algae is a unicellular, prokaryotic (pro= primitive, karyon= nucleus) organism. It does not have a well-defined nucleus. The DNA is not present inside the nucleus (means the DNA is naked) rather it is present in the cytoplasm (not enclosed by the nuclear membrane). DNA has no histone protein.
Why is blue-green algae a bacteria?
Blue-green algae is a form of bacteria, so the cells interact with water differently than true algae, almost appearing to be a part of a water.
Is blue-green algae a symbiotic bacteria?
Blue-green algae and symbiotic bacteria both convert free nitrogen into nitrogenous compounds such as ammonia, nitrate, nitrites with the help of enzyme nitrogenase. They fix atmospheric nitrogen into products which can be used by the plants. In return, they get food from plants in the form of sugar.
How can you tell the difference between green algae and blue green algae?
Furthermore, a significant difference between blue green algae and green algae is that the blue green algae do not possess chloroplasts, and other membrane-bound organelles while green algae possess chloroplasts and membrane-bound organelles.
How can you tell if blue green algae is present?
Freshwater blue-green algal blooms can be recognised by: discolouration of the water, by scum on the water surface, or. by an earthy or musty odour coming from the water.
What do bacteria and blue-green algae have in common?
(4) Both bacteria and blue-green algae lack mitochondria, true vacuoles and an endoplasmic reticulum. Membranous structures (mesosomes) are widespread in bacteria and recently similar structures have been seen in blue-green algae.
What is an example of blue-green algae?
Examples of cyanobacteria: Nostoc, Oscillatoria, Spirulina, Microcystis, Anabaena.
What kills blue-green algae?
Copper Sulfate or “blue stone” is probably the most commonly used algal treatments because of its availability and low cost. Copper sulfate comes in several forms depending on how finely it is ground.
