Marine protozoans lack contractile vacuole because
1 osmoregulation is done by cell membrane
2 they are hypo-osmotic to their environment
3 they are isotonic with their environment
4 their small body cannot accommodate it
Explanation:
The marine protozoan live in hypertonic environment. They loss water due to exosmosis. It prevents water loss and conserve water in the body. - The marine protozoa lack contractile vacuole. - They are hypo-osmotic to their environment contractile vacuole help to remove excess water and perform osmoregulation.

Amoeba is a/an:
1 unicellular animal
2 octacellular animal
3 multicellular anima
4 all of the above
Explanation:
Amoeba is a unicellular animal protozoa, it is single cell organism. - Pseudopodia help in osmoregulation. - No stomach present in amoeba storage of food and digestion take place inside the food vacuole in the cytoplasm of amoeba.

Sporogony of malarial parasite occur in:
1 liver of man
2 stomach wall of mosquito
3 RBCs of man
4 salivary glands of mosquito
Explanation:
Sporogony of malarial parasite occurs in stomach wall of female Anopheles mosquito. - Some merozoites form gametocytes which are sucked by mosquito along with blood followed by gamete formation inside the stomach of female Anopheles.

Schizogony of Plasmodium is also called as
1 sporogony
2 gamogony
3 agamogony
4 binary fission
Explanation:
Schizogony of Plasmodium is also called as agamogony because it is also the process of formation of new individual by cell division. Agamogony is an asexual process and the product of schizogony generally grows into trophozoites.
