Question

Cyanobacteria are classified under which of the following kingdoms?

• A. Monera
• B. Protista
• C. Algae
• D. Plantae

Answer 1

Answer: (A)

Monera

Bacteria are the sole members of the Kingdom Monera. They include Archaebacteria and Eubacteria. Archaebacteria differ from other bacteria in having a different cell wall structure and this feature is responsible for their survival in extreme conditions. Eubacteria are characterized by the presence of a rigid cell wall and if motile, a flagellum. Cyanobacteria have chlorophyll a similar to green plants and are photosynthetic autotrophs. The cyanobacteria are unicellular, colonial, or filamentous, freshwater marine or terrestrial algae.

So the correct option is "Monera".
