Asexual Reproduction • Binary fission • Plasmotomy • Budding • Multiple fission • Plasmogamy.

Nutrition in Protozoa • Protozoa obtain nourishment in many ways. They are: — Holozoic Nutrition — Holophytic Nutrition — Saprophytic or Saprozoic Nutrition — Parasitic Nutrition — Coprozoic Nutrition — Mixotrophic Nutrition.

LOCOMOTION METHOD •Amoeboid Movement • Flagellar Movement • Ciliary Movement • Metabolic Movement.

LOCOMOTORY ORGANELLES • Pseudopodia • Flagella • Cilia • Pellicular Contractile Structures.

Lobopodia Filopodia Pseudopodia Reticulopodia Axopodia.

CLASS: SARCODINA Body naked or with internal shells or external • tests. • With Pseudopodia for locomotion & food capture. Amoeboid during most of life cycle. • No spore formation, no Conjugation. • Mostly free living. •.

CLASS: SPOROZOA Body covered with a thick pellicle. • No locomotory organ , mouth and contractile vacuoles are present. Nutrition Saprozoic. • Asexual reproduction by multiple fission. Sexual reproduction by spore formation. • Life cycle complex . All internal parasites. •.

CLASS: MASTIGOPHORA • Body covered by thin Pellicle or test of Cellulose, Chitin or Silica. • One to many flagella for locomotion & food capture, some with Pseudopodia. • Nutrition Autotrophic, Heterotrophic Mixotrophic. • Asexual Reproduction or by Longitudinal fission. • No spore formation .No Conjugation. • Free living or Parasitic..

CLASS: CILIATA • Complex Protozoa with a firm pellicle. • Locomotory organelles cilia or sucking tentacles , in at least one stage of life cycle. • Nuclei of 2 kind. (dimorphic) • Nutrition holozoic. • Asexual reproduction by binary fission. • Sexual reproduction by conjugation and auto ga my..
