Class 8 Reproduction in Animals
Learn about the various reproductive processes of animals, including external and internal fertilisation, viviparous and oviparous animals, metamorphosis, and asexual reproduction through budding and binary fission, in this comprehensive guide to Class 8 Reproduction in Animals.
Q: What is sexual reproduction?
Sexual reproduction is a type of reproduction that involves the fusion of male and female gametes.
Q: What are the male reproductive organs?
The male reproductive organs include a pair of testes, two sperm ducts, and a penis.
Q: What do the testes produce?
The testes produce male gametes called sperms.
Q: What are the female reproductive organs?
The female reproductive organs include a pair of ovaries, oviducts (fallopian tubes), and the uterus.
Q: What do the ovaries produce?
The ovaries produce female gametes called ova (eggs).
Q: Where does the development of the baby take place?
The development of the baby takes place in the uterus.
Q: What is fertilisation?
Fertilisation is the process in which a sperm and an ovum fuse together, resulting in the formation of a fertilised egg or zygote.
Q: What happens during fertilisation?
During fertilisation, the nuclei of the sperm and the egg fuse to form a single nucleus.
Q: What is inherited by the new individual during fertilisation?
The new individual inherits some characteristics from the mother and some from the father.
Q: What is internal fertilisation?
Internal fertilisation is the process of fertilisation that takes place inside the female body.
Q: Name some animals that undergo internal fertilisation.
Some animals that undergo internal fertilisation include humans, cows, dogs, and hens.
Q: What is external fertilisation?
External fertilisation is the type of fertilisation in which the fusion of a male and a female gamete takes place outside the body of the female.
