Protozoa (Greek: Protos- First and Greek: Zoon- Animal). Thus, Protozoa is the first animal.  Protozoa are another group of eukaryotic protists. Sometimes between algae and protozoa is less clear the difference. Most Protozoa can only be seen under a microscope.


Some organisms have properties between algae and protozoa. As an example of the green algae of Euglenophyta, the cells are fluctuated and are single chlorophyll cells, but may experience chlorophyll loss and the ability to photosynthesize. 


All Euglenophyta species are capable of living in complex nutrients in the absence of light, some scientists put it into protozoan phyla. For example, mutant strains of Chlamydomonas genus algae that are not chlorophyll, can be incorporated into the Protozoa class of the genus Polytoma.


This is an example of how difficult it is to distinguish firmly between algae and protozoa. Protozoa are distinguished from prokaryotes because of their larger size, and their cells are eukaryotic. Protozoa are distinguished from algae because they are not chlorophyll, distinguished from fungus because they can move actively and not cell-walled, as well as distinguished from mucus fungus because it can not form a fruit body.
