Protozoa carried out their reproduction by asexual and sexual mode of reproduction. The higher group of protozoa follow mainly sexual reproduction. Some protozoa carried out both asexual and sexual reproduction based on the types of the host cells.
The size and shape of protozoa vary based on the types of species. For example, the causative agent of Kala azar, Leishmania donovani has a size range of 1 to 4 micrometers in length, while the Amoeba proteus is 600 micrometers or more in size. Some members of ciliates can reach 2,000 micrometers or 2mm.
Protozoa are unicellular, microscopic, eukaryotic protists which are found in everywhere such as water; soil, on the body of plants and animals. They lack a cell wall and their size ranges from 5 to 250 micrometers.
The term protozoa comes from the Greek word protos and Zoon, which means “first animal”. Protozoa are microscopic single-celled, eukaryotic protists that lack cell walls. The size of protozoa varies from 5 to 250 micrometers. The detailed study of protozoa is known as protozoology.
