When fresh water protozoan is placed in marine water.
1 The number of contractile vacuoles increase
2 The contractile vacuoles become bigger in size
3 The contractile vacuoles remain unchanged.
4 the contractile vacuoles disappear.
Explanation:
The contractile vacuoles disappears, when a freshwater protozoan is placed in marine water. There function is to remove the excess water outside by the process of osmoregulation. In marine water, it is necessary to retain the water inside the body instead of expelling it out. If the contractile vacuoles, will not disappear, the cell will get dehydrated.

Which of the following results from conjugation in Paramecium?
1 Cell death
2 Cell division
3 Budding
4 Recombination
Explanation:
In paramecium, conjugation is a form of sexual reproduction, which is a temporary union of two individuals of the same species for the mutual exchange of genetic materials. The ventral surfaces attach and the exchange of genetic material starts by the formation of the cytoplasmic bridge. Here, the male pronucleus fuses with the female pronucleus to form a diploid zygote which forms a mature organism. This results in recombination.

Name the protozoan parasite with a food vacuole.
1 Leptomonas
2 Plasmodium
3 Trypanosoma
4 Leishmania
Explanation:
The protozoan parasite with a food vacuole is Plasmodium. Here food vacuole is a lysosome-like organelle, where erythrocyte hemoglobin digestion occurs.
