Protozoans are unicellular with
some similar to animal
cells.

comparison to pluricellular
protozoans are more to the
animal than to plants: are
heterotrophs, they a rudimentary
locomotion (amoeboid
movements,cilia, flagella), do not
have wall, some species
structures that resemble of a
primitive system, with

The evolutionary hypothesisthat
cells have come differentiation of
