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. <em /> Lastly, protists that do not have locomotive organelles are exemplified by <em>Plasmodium </em>species, the etiologic agent of malaria.
a learning process that occurs when two stimuli are repeatedly paired; a response that is at first elicited by the second stimulus is eventually elicited by the first stimulus alone.
