multicellular organisms
organisms that are made up of one cell
Unicellular means one cell. . So naturally a unicellular organism such as plankton, would be unicellular. .
A unicelluar prokaryote doesn't hav ea membrane, while a unicelluar euryote has a cell membrane. ;) hope this helps -from an awesome smart person
name one major way that unicellular protists are different than unicellular bacteria?
