protista
This Kingdom is eukaryotic. Like Archaebacteria and Eubacteria, this kingdom is unicellular, meaning that the whole organism is only one cell. The Protista kingdom is also both heterotrophic and autotrophic. Even though this kingdom mainly lives in watery ecosystems, it can live practically anywhere. Unlike Archae and Eubacteria though, these organisms are both sexual and asexual reproducers. Some examples of this kingdom are diatom(Bacillariophyceae), plankton(Camba), Amoeba(Proteus animalcule), euglena(Euglenaphyta), and algae(Rhodophyta). Like Plantae(plants), these organisms contain cellulose in there cell walls. this makes the walls very rigid and not very flexible.
