Key concepts: Reproduction in Animals (Class 8 Science)
This chapter covers sexual and asexual reproduction in animals, fertilisation, development of the embryo, and modes of reproduction.
- Modes of reproduction
- Sexual (involves two parents and gametes) and asexual (single parent, e.g. budding in hydra, binary fission in amoeba).
- Gametes & fertilisation
- Fusion of the male gamete (sperm) and female gamete (egg/ovum) forms a zygote.
- Internal vs external fertilisation
- Internal (inside the body, e.g. humans) vs external (outside, e.g. frogs and fish in water).
- Development
- The zygote divides to form an embryo, which develops into a foetus and then a young one.
- Viviparous & oviparous
- Viviparous animals give birth to young ones (e.g. humans); oviparous animals lay eggs (e.g. hens).
💡 Exam tips for Reproduction in Animals
- Budding (hydra) and binary fission (amoeba) are the standard examples of asexual reproduction.
- Viviparous = gives birth to young; oviparous = lays eggs — a common one-mark distinction.
Sample questions
Reproduction that involves two parents and the fusion of gametes is called:
Sexual reproduction involves a male and a female parent whose gametes fuse.
Why does external fertilisation usually involve the release of a very large number of eggs?
In water, many eggs are lost to predators and currents, so producing many improves survival odds.
Assertion (A): Fish and frogs release thousands of eggs. Reason (R): External fertilisation in water has a high loss of eggs, so large numbers improve survival. Choose the correct option.
Heavy egg loss in water is exactly why so many eggs are released — R explains A.
