FAQs on Earthworm: Male Reproductive System Video Lecture - Biology for Grade 11

1. What is the male reproductive system of an earthworm?
Ans. The male reproductive system of an earthworm consists of testes, seminal vesicles, seminal funnels, and male genital pores. The testes produce sperm cells, which are then stored in the seminal vesicles. The seminal funnels collect sperm from the seminal vesicles and transfer it to the male genital pores for mating.
2. How do earthworms reproduce?
Ans. Earthworms are hermaphrodites, meaning they have both male and female reproductive organs. During mating, two earthworms exchange sperm. The sperm is then stored in the seminal vesicles until the earthworms lay eggs. Each earthworm can lay a cocoon containing several eggs, which will eventually hatch into baby earthworms.
3. What is the purpose of the male reproductive system in earthworms?
Ans. The male reproductive system in earthworms is responsible for producing and delivering sperm cells for fertilization. Earthworms have both male and female reproductive organs, allowing them to exchange sperm during mating. The male reproductive system ensures the transfer of sperm to the female reproductive system for successful fertilization.
4. How do earthworms fertilize their eggs?
Ans. After mating, earthworms lay cocoons containing eggs. Each cocoon contains multiple eggs, which are fertilized internally by the exchanged sperm. The sperm cells travel from the seminal vesicles of one earthworm to the female reproductive system of the other, where they fertilize the eggs. The fertilized eggs develop within the cocoon until they hatch into baby earthworms.
5. Can earthworms reproduce asexually?
Ans. While earthworms are primarily hermaphrodites and reproduce through sexual reproduction, they can also reproduce asexually under certain conditions. If an earthworm gets fragmented, each fragment has the ability to regenerate and develop into a new individual, essentially cloning itself. This asexual reproduction method is known as fragmentation or fission. However, sexual reproduction is the primary mode of reproduction for earthworms.
