What color is Cyanophyta?
Cyanobacteria, which are often called blue algae, can actually adopt colours ranging from green to orange via pink, depending on the dominant photosynthetic pigment in the cells of particular species.
What is the common name of Cyanophyta?
Cyanobacteria (/saɪˌænoʊbækˈtɪəri. ə/), also known as Cyanophyta, are a phylum of Gram-negative bacteria that obtain energy via photosynthesis.
How big is a cyanobacterium?
0.5 to 60 micrometres
Cyanobacteria range in size from 0.5 to 60 micrometres, which represents the largest prokaryotic organism. They are widely distributed and are extremely common in fresh water, where they occur as members of both the plankton and the benthos.

Which is blue-green algae?
Blue-green algae are actually types of bacteria known as Cyanobacteria. They normally look green and sometimes may turn bluish when scums are dying. Taste and odour problems commonly occur with large concentrations of blue-green algae and some species are capable of producing toxins.
Does cyanophyta have flagella?

Where does cyanobacteria come from in aquarium?
The primary causes of blue-green algae in your aquarium include: Cyanobacteria was introduced into the aquarium (on a plant or from the water source) Excess light2 High levels of organic wastes.
What do Microcystins do?
Microcystin is a potent liver toxin and possible human carcinogen. Cyanotoxins can also kill livestock and pets that drink affected waters. Fish and bird mortalities have also been reported in water bodies with persistent cyanobacteria blooms.
