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).
