Which among the following organisms is/are not monoecious?NereisEarth wormLeechBoth A and C
Solution
The term "monoecious" refers to organisms that have both male and female reproductive organs in the same individual.
-
Nereis: Nereis is a genus of polychaete worms in the family Nereididae. They are dioecious, meaning they have separate sexes, so they are not monoecious.
-
Earthworm: Earthworms are monoecious, meaning they have both male and female reproductive organs in the same individual.
-
Leech: Leeches are also hermaphrodites, meaning they are monoecious.
So, among the given organisms, Nereis is not monoecious. Therefore, the answer is "A. Nereis".
