Question

what are the important characters of cynobacteria​

Answer 1

Cyanobacteria are prokaryotic oxygenic phototrophs that contain a green pigment called chlorophyll and a blue photosynthetic pigment called phycobilins. Prokaryotic means they don't have a membrane-bound nucleus, mitochondria or other type of membrane-bound organelle (like true algae do).

Cyanobacteria Structure

Cyanobacteria cells, which are typically one-tenth to one-twentieth the size of eukaryotic cells, are round in shape.

Cyanobacteria Characteristics

Defining cyanobacteria characteristics are a tolerance of extreme conditions and an ability to exist without vitamins. They use phosphorus, iron and other micronutrients, and ammonia or nitrate as a nitrogen supply. Some types of cyanobacteria are filamentous and don't need sunlight. Instead, they grow in the dark, relying on sugar from glucose or sucrose as a carbon and energy source.
