AIIMS 2019 Zoology Earthworm Anatomy MCQ Question
A single female genital pore is present on the segment through which female reproductive bodies (ova) are discharged during copulation. The segments 14-16 of a matured
earthworm consist of a glandular tissue called clitellum which helps to distinguish the mouth and tail end.
Correct Answer
Detailed Explanation
The presence of a single female genital pore on the 14th segment indicates that the organism is a hermaphroditic species, such as the earthworm, where ova are released during copulation. The segments 14-16 form the clitellum, a glandular structure that plays a crucial role in reproduction by secreting a cocoon for fertilized eggs, distinguishing the anterior and posterior ends of the worm. Option B is correct because it implies that the segments are involved in reproductive functions, while the other options are not applicable or lack relevant information about the reproductive anatomy of the earthworm.
