In Amoeba and Paramecium osmoregulation occurs through

  1. Pseudopodia

  2. Nucleus

  3. Contractile vacuole

  4. General surface

Show answer
Correct Option: C
Explanation:
Osmoregulation is the maintenance of constant osmotic pressure in the fluids of an organism by the control of water and salt concentration. In Amoeba and paramecium, the osmoregulation occurs through Contractile vacuole. The function of a contractile vacuole in protozoan is to expel out excess water via diffusion.
So, the correct answer is 'Contractile vacuole'.

If all ponds and puddles are destroyed, the organism likely to be destroyed is

biology the world of microbes protista protozoa five kingdoms of living organisms

  1. Leishmania

  2. Trypanosoma

  3. Ascaris

  4. Plasmodium

Show answer
Correct Option: D
Explanation:
The breeding places of this mosquito is ponds, marshes, swampy areas etc. So, if all the ponds and puddles are destroyed. Anopheles will not be able to survive leading to destruction of its parasite, Plasmodium.
So, the correct answer is 'Plasmodium'

Protistan genome has

  1. Membrane bound nucleoproteins embedded in cytoplasm

  2. Free nucleic acid aggregates

  3. Gene containing nucleoproteins condensed together in loose mass

  4. Nucleoprotein in direct contact with cell substance

Show answer
Correct Option: A
Explanation:

Protista are eukaryotic organism. They have well defined membrane bound nucleus, which encloses genetic material and membrane bound cell organelle in cytoplasm.

Therefore the correct option is A.

What is not connected with reproduction of protozoans?

biology the world of microbes protista protozoa five kingdoms of living organisms

  1. Cryptogamy

  2. Schizogamy

  3. Autogamy

  4. Conjugation

Show answer
Correct Option: B
Explanation:

Schizogeny is the method of reproduction in which production of a sexual individual from an asexual form usually by fission.

Cryptogamy involves new individuals with spores without the formation of seeds or flowers.
Autogamy is a type of reproduction in which the production of offspring is done by the fusion of two gametes from the same individual.
Conjugation is the process of reproduction in which the genetic material is transferred between two cells by a direct cell to cell contact.
So the correct answer is yes 'Schizogamy'.
