Classification of Protozoa by Levine et al(1980)
Subkingdom :- Protozoa
Characters :-
(i) They are usually microscopic & single celled animal & the single cells performs all the vital
activities of the body.
(ii) Body may be naked or covered by pellicle or enclosed in a shell.
(iii) Main locomotory organs are pseudopodia, flagella or cilia (in sporozoa well define locomotory
organs are absent).
(iv) Nucleus single or multiple, which in sac like, oval or biconvex & contains a thick endosome.
Phylum :- Sarcomastigophora
Characters :-
(i) Locomotory organs pseudopodia or flagella.
(ii Nucleus monomorphic.
(iii)Reproduction by fission or syngamy.
Examples :- Amoeba; Trypanosoma; Euglena; Opalina; Entamoeba; Leishmania;
Phylum :- Apicomplexa
Characters :-
(i) It possess an apical complex which can be seen under electron microscope.
(ii) All are generally inter cellular parasite & lack locomotory organ.
(iii) Micropore may be present at certain stage.
Examples :- Plasmodium; Monocystis;
Phylum :- Ciliophora
Characters :-
(i) Locomotory organs are simple cilia or complex ciliated organelles.
(ii) Nucleus are of two types, one micro nucleus & other macro nucleus.
(iii) Presence of cytostome & cytopyge.
Examples :- Paramoecium; Balantidium; Nyctotherus; Tetrahymena;
Phylum :- Myxozoa
Characters :-
(i) Multicellular origin of spore.
(ii) Polar capsule one to many.
(iii) All are parasites in the blood or coelom or cells of cold blood vertebrates.
Example :- Myxozoa
Phylum :- Microspora
Characters :-
(i) Spore single celled, spore wall is without any pore.
(ii) Sporoplasm is with one or two nuclei.
(iii)Polar cap & polar tubules are always present.
Example :- Microspora;
Phylum :- Ascetospora
Characters :-
(i) Spores are generally multicellular, may be single celled.
(ii) All are parasite.
(iii) Sporoplasm may be one or two or many types.
Example :-Ascetospora;
