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

1. What is the purpose of the female reproductive system in earthworms?
Ans. The female reproductive system in earthworms is responsible for producing and releasing eggs for reproduction. It plays a crucial role in the process of sexual reproduction in earthworms.
2. How does the female reproductive system in earthworms work?
Ans. The female reproductive system in earthworms consists of two ovaries, oviducts, and a seminal receptacle. The ovaries produce eggs, which then pass into the oviducts. The seminal receptacle stores sperm received during mating. Fertilization occurs inside the oviducts, and the eggs are subsequently laid.
3. Can earthworms reproduce without a male?
Ans. No, earthworms require both male and female individuals for sexual reproduction. Each earthworm has both male and female reproductive organs, but they cannot self-fertilize. Mating between two earthworms is necessary for successful reproduction.
4. How many eggs does a female earthworm typically produce?
Ans. A female earthworm can produce a large number of eggs during a single reproductive cycle. The exact number varies depending on the species and environmental conditions. Some earthworm species can produce hundreds of eggs at a time.
5. What factors influence the reproductive capacity of female earthworms?
Ans. The reproductive capacity of female earthworms can be influenced by various factors such as age, size, nutrition, environmental conditions, and availability of mating partners. Adequate nutrition and favorable environmental conditions often result in higher egg production in female earthworms.
