RBSE Class 8 Science Chapter 9 Notes Reproduction in Animals

→ In animals sexual and asexual reproduction is present. In sexual reproduction male and female gamete fuse.

→ The reproductive organs in male is testes, sperm ducts and penis while the female reproductive organs includes ovaries, oviducts and uterus.

→ The fusion of ovum and sperm is called fertilization. The fertilized egg is called a zygote. Fertilization that takes place inside the female body is called internal fertilization and which takes place outside the female body is called external fertilization.

→ The zygote divides to give rise an embryo. The embryo gets embedded in the wall of the uterus and gets nutrition.

→ Animals which give birth to young one are viviparous animals and animals which lay eggs are called oviparous animals.

→ Reproduction in which only a single parent is involved is called asexual reproduction. This takes place by budding and binary fission method.
