a.
Rhizopoda(Sarcodina)
1.
They are mostly free living and are found in
fresh water, ocean water, and damp soil. Few are parasitic (Entamoeba).
2.
Pseudopodia are the organelle for locomotion and
catching food.
3.
Pellicle
doesn’t cover them.
4.
They are
halozoic in nutrition.
5.
They reproduce asexually by binary fission and
multiple fission and reproduce sexually by syngamy.
Eg : amoeba, entamoeba etc.
b.
Ciliata (Infusoria)
1.
They are free-living and are found in fresh
water and marine water. Few are
parasitic and pathogen.
2.
Their body is covered with pellicle.
3.
Cilia are organelle for locomotion and catching
food.
4.
They are halozoic in nutrition.
5.
They reproduce asexually by binary fission and
cyst formation in unfavorable condition. They reproduce sexually by conjuction.
Eg : paramecium, balantidium etc
c.
Mastigophora(flagellate)
1.
They are common as aquatic, parasitic, free-living, commensel or symbiotic organism.
2.
Their body is covered with pellicle.
3.
Flagella are organelle for locomotion and
catching food.
4.
They are heterotrophic in nutrition.
5.
They reproduce asexually by binary fission only.
Sexual reproduction doesn’t take place.
Eg : euglena, giardia etc
d.
Sporozoa
1.
They are
endo-parasitic and pathogenic. They cause diseases.
2.
Their body is covered with pellicle.
3.
They don’t have locomotory organ and contractile
vacuole.
4.
They are sporozoic in nutrition.
5.
They reproduce asexually by multiple fission and
sexually by spore formation.
Eg
: plasmodium, monostis etc
