Protozoa

A very diverse group comprising some 50,000 eukaryotic organisms that consist of one cell. Because most of them are motile and heterotrophic, the Protozoa were originally regarded as a phylum of the animal kingdom. However it is now clear that they have only one common characteristic, they are not multi-cellular, and Protozoa are now usually classed as a Sub-Kingdom of the Kingdom Protista. On this classification the Protozoa are grouped into several phyla, the main ones being the Sarcomastigophora (flagellates, heliozoans and amoeboid-like protozoa), the Ciliophora (ciliates) and the Apicomplexa (sporozoan parasites such as Plasmodium > Plasmodium). ...

Historically, protozoa were defined as unicellular protists with animal-like behaviour, such as movement. Protozoa were regarded as the partner group of protists to protophyta, whic...
