Which of the following microorganisms have a cell wall?
All algal, fungal and bacterial cells possess cell walls. The algal cell wall is mainly composed of cellulose, fungal cell wall composed of chitin and bacterial cell wall composed of peptidoglycan.
Protozoa are single-celled eukaryotes that commonly show characteristics usually associated with animals, most notably mobility. Like animal cells, protozoans also lack a cell wall.
