Eukaryote organisms have one or more cells with a nucleus and other organelles enclosed within membranes.
- 5.1: Protozoa
- Protozoa are unicellular eukaryotic microorganisms lacking a cell wall and belonging to the Kingdom Protista. The vegetative, reproducing, feeding form of a protozoan is called a trophozoite. Under certain conditions, some protozoa produce a protective form called a cyst that enables them to survive harsh environments. Cysts allow some pathogens to survive outside their host.
- 5.2: Fungi
- Yeasts are eukaryotic microorganisms classified as members of the fungus kingdom with 1,500 species currently identified and are estimated to constitute 1% of all described fungal species.
