Protozoa

Protozoa (singular: protozoan) are unicelluar eukaryotic organisms. Protozoa are unlike classic bacteria (prokaryotes), which do not contain nuclei or membrane-bound organelles, and metazoa (multicellular organisms), which are conglomerates of many eukaryotic cells.

Protozoa are the most abundant life forms on Earth, in number and biomass.[1]
