- PROTOPLASMIC GRADE OF ORGANIZATION
- TERM PROTOZOA WAS GIVEN BY GOLDFUSS.
- Usually asymmetrical but giardia is bilaterally symmetrical
- Food is first acidic then alkaline. Digestion in alkaline mode
- Respiration through the general body surface.
- Excretion through general body surface or contractile vacuole and are ammononotelic
- Note; organism living in water are called ammonotelic
- Contractile vacuole helps in performing the osmoregulation in fresh water and also helps in removing the excretory product
- Tse-Tse fly (Glossina palpalis) is the carrier of trypanosome in man
- Holozoic type of nutrition
- Kala-azar is the disease caused by protozoa ( leishmania donovani)
- Kala-azar is transmitted by sand fly (Plebotomous argentipus)
- Protozoa is the class that does not carry its name after its locomotary organ.
- Dysentery is caused by Entamoeba histolytica.
- Reproduction by fission is the commonest feature of plasmodium and paramecium.
- Due to heterotrophic nutrition protozoa are called animals
- When a marine protozoon is transferred to a fresh medium it enlarges but become normal again
- Sol-gel theory was given by Hyman.
- By the method, circumvallation, amoeba capture its active prey.
- Pinocytosis is technically expressed as the cell drinking
- Entamoeba histolytica in man is found in colon
- Quadrinucleated cyst is the infective stage of entamoeba histolytica.
- In unfavorable condition, amoeba reproduce by sporulation
