Unicellular organism
From Wikipedia, a free encyclopedia written in simple English for easy reading.
Unicellular organisms are organisms that only have one cell. Unicellular organisms are normally from two classification kingdoms; Eubacteria and archaebacteria. Unicellular is normally either a eukaryote (a cell with a nucleus) or a prokaryote (a cell without one). They reproduce asexually and do not have specialized functions. E. Coli and amoeba are examples of unicellular organisms. E.Coli is a bacteria and amoeba is a protist.
