i m too looking for the answer for the same question.
dii, plz also add example like Euglena ,Monocystis ,Paramecium.
  1. PHYLUM: PROTOZOA Classification By: AAKRIT

  2. PHYLUM Protozoa SUBPHYLUM-Sarcomastigophora Sporozoa Cnidospora Ciliophora SUPER CLASS 1. Mastigophora CLASS Phytomastigophora Teleospora Myxosporidea Ciliatea Eg: Myxobolus Eg: Paramoecium Vorticella Balatidium Eg: Euglena, Ceratium, Eg: Monocyctis, Eimera, Noctiluca Plasmodium Zoomastigophora Toxoplasmea Eg: Toxoplasma Microsporidea Eg: Leishmania, Trichomonas, Eg: Nosema bombycis Trypanosoma, Trichonympha 2. Opalinata Haplosporea Eg: Haplosporidium Eg: Opalina, Zelleriella 3. Sarcodina Rhizopodea Eg: Amoebo, Entamoeba, Elphidium Piroplasmea Eg: Babesia Actinopodea Eg: Actinophrys, Collozoum

  3. .SUBPHYLUM 11: SPOROZOA .The animals belonging to this subphylum are exclusively endoparasites Special locomotory organelles are absent in these animals. .Sometimes pseudopodia are present which are useful only for ingestion of food. Sporozoites are merozoites bear anterior apical complex that helps penetrate host cells. This subphylum includes 3 classes:

  4. Class 1: Telosporea The Sporozoites are long in these animals. Reproduction is both asexual and sexual. They are blood and gut parasites of vertebrates. . Sexual reproduction is by isogamy or anisogamy. Ex:Monocyctis, Eimera, Plasmodium

  5. Class 2: Toxoplasmea: In this class reproduction is only asexual type which takes place by internal budding where two daughter cells are produced within the mother cell and the mother cell is finally destroyed in the process of reproduction. Spores are absent. Ex:Toxoplasma

  6. Class 3: Haplosporea: . The spores in this class are amoeboid. Also reproduction is only asexual type taking place through multiple fissions. Ex:Haplosporidium, Ichthyosporidium

  7. SUBPHYLUM III: CNIDOSPORA(Gr. Knide-nettle; spora-seed) The animals belonging to this subphylum are parasitic. Special kind of locomotory organelles are absent in these animals. .Spores are present with one or more polar filaments. Polar filaments are special and unique features of these animals. . When these spores infect a host, the polar filament is discharged and it gets attached to the host tissue. This subphylum includes 2 classes:

  8. Class 1: Myxosporidea: The spores of the animals of this class are large and develop from several nuclei. These are generally extracellular parasites. . The spores of this class have two polar filaments and have two to three valves. Ex:Myxobolus

  9. Class 2: Microsporidea: The spores of the animals of this class are small and are developed from only one nucleus. These spores have single valve These are generally intracellular parasites. . Many of the animals of this class have a single polar filament. Ex:Nosema bombycis

  10. SUBPHYLUM IV: CILIOPHORA(La. Cilium eye lid with lashes; phoros-bearing) Ciliophorans are complex of all the protozoans. * The locomotory organelle of all the animals of this subphylum is cilia These cilia also help in feeding at some stage of the life cycle of the animals. . The nuclei of these organisms are dimorphic. Macronucleus is vegetative and polyploid. Micronucleus is reproductive and diploid . Asexual reproduction takes place by binary fission. Sexual reproduction takes place by conjugation Only one class is included in this subphylum:
