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.
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.
