CHRYSAMOEBA

CLASSIFICATION OF CHRYSAMOEBA

PHYLUM :- PROTOZOA (Unicellular)

SUB-PHYLUM :- PLASMODROMA (Cilia absent, locomotion by pseudopodia)

CLASS :- MASTIGOPHORA (One or more flagella)

SUB-CLASS :- PHYTOMASTIGINA (Chromatophores present)

ORDER :- CHRYSOMONADINA (Amoeboid forms)

GENUS :- Chrysamoeba

GEOGRAPHICAL DISTRIBUTION

  • It is found everywhere.

HABIT AND HABITAT

  • Chrysamoeba is one of the simplest, plant-like form, found in fresh-water without cuticle and skeleton.

CHRYSAMOEBA PROTOZOA

GENERAL CHARACTERSTICS OF CHRYSAMOEBA

  • Typically small mastigophora provided with a single flagellum, 2 yellow chromatophores, single nucleus and 2 or more contractile vacuoles.
  • It occurs in flagellate and amoeboid forms. 
  • During swimming, body becomes oval but on substratum, it becomes amoeboid and may lose flagellum temporarily. 
  • Pseudopodia radiate from the cytoplasm. 
  • It manufactures its food by photosynthesis.
  • Like Amoeba, it also ingests solid food particles. Nutrition is holozoic. 
  • Chrysomonadina are supposed to be more primitive than Amoeba, because amoebae do not contain flagella and feed only like animals. 
  • Chrysamoeba belongs to order chrysomonadina and the whole order exhibits strong amoeboid tendencies.

IDENTIFICATION

  • the animal contains radiating pseudopodia and all above features, hence it is Chrysamoeba.
