Answer» The four major groups of PROTOZOA are:
• Amoeboid protozoans: These organisms live in fresh water, sea water or moist soil. They move and capture their prey by putting out pseudopodia (false feet) as in AMOEBA.
Flagellated protozoans: The members of this GROUP are either free-living or PARASITIC. They have flagella.
Ciliated protozoa or CILIATES: They are aquatic individuals that form a large group of protozoa.
Sporozoans: They include disease causing endoparasites and other pathogens. They are uninucleate and their body is covered by a pellicle.
