Each individual cell (each single cyanobacterium) typically has a thick, gelatinous cell wall. They lack flagella, but hormogonia of some species can move about by gliding along surfaces.

Does cyanobacteria have a cell wall or cell membrane?

The cells of the cyanobacteria possess the cell wall, where they have 3 layers that show compartmentalization, and have a thick layer of the peptidoglycan, that makes the cyanobacteria not get stained and it is gram negative bacteria.

What is the cell wall of cyanobacteria?

Cell walls of cyanobacteria are composed of a peptidoglycan layer and an outer membrane. Outer membrane constituents include proteins, lipids and carotenoids (Drews & Weckesser, 1982; Resch & Gibson, 1983; Omata & Murata, 1984; Jurgens & Weckesser, 1985; Benz & Bohme, 1985).
