Amoebae (or amoebas) are a group of single-celled organisms that are defined by certain morpholigical characteristics (see below), but are not necessarily closely related to one another (i.e. they are paraphyletic). They are, however, all eukaryotes, meaning that they are more closely to animals, plants, fungi, etc. than they are to prokaryotes like bacteria.

General Life CycleEdit

Most amoebae reproduce by binary fission (one cell splits in two) and have a feeding stage (often referred to as a trophozoite) and a resistant stage (a cyst). 

Morphological CharacteristicsEdit

Amoebae are identified by being single-celled and moving using pseudopodia, or temporary extensions of the cell.
