Question

Which of the following organisms does NOT show asexual reproduction by means of fission?

A.

Plasmodium

B.

Earthworm

C.

Amoeba

D.

Leishmania

Correct option is B

Correct Answer: (b) Earthworm

Explanation:

·         Earthworm does not reproduce through asexual reproduction by fission. Earthworms are hermaphrodites (possessing both male and female reproductive organs) and reproduce sexually through the exchange of gametes during copulation.

·         They do not undergo fission, which is a form of asexual reproduction.

Other Options:

  • Plasmodium: Plasmodium reproduces asexually through multiple fission during its lifecycle in the human liver and red blood cells.
  • Amoeba: Amoeba reproduces asexually through binary fission, where the parent cell splits into two daughter cells.
  • Leishmania: Leishmania reproduces asexually through binary fission, but the division occurs longitudinally (along the length of the organism).
