natta225 [31]
In simple terms, there are 4 categories of protists in basic biology characterized by their type of locomotion.

Locomotion by pseudopods or "false feet" is characteristic of ameobas (i.e. <em>Entamoeba histolytica</em>). Locomotion by papillary projections from the cell membrane called "cilia" is characteristic of <em>Paramecium </em>species. Locomotion by whip-like structures that propel the organism called "flagella" is characteristic of <em>Euglena </em>species.

Lastly, protists that do not have locomotive organelles are exemplified by <em>Plasmodium </em>species, the etiologic agent of malaria.
