Explain why cyanobacteria is not a true bacteria?

Cyanobacteria, also known as blue-green algae, are not considered true bacteria because they are a type of photosynthetic prokaryotic organism that is more closely related to algae and plants than to bacteria. Cyanobacteria have chlorophyll and other pigments that allow them to carry out photosynthesis, similar to plants and algae. Additionally, cyanobacteria have specialized structures called thylakoids that are involved in photosynthesis, which are not found in true bacteria. These characteristics set cyanobacteria apart from true bacteria and place them in a separate group of organisms.

Cyanobacteria are considered true bacteria and do not belong to a different group. They are classified within the domain Bacteria and the phylum Cyanobacteria.
