This chapter is based on process of reproduction in animals. Reproduction is important for the survival of species. The chapter explains how living beings create new life through two methods: sexual and asexual reproduction. In the chapter, you will be learning about important keywords like fertilisation, zygote, and embryo. Simple examples like frogs, dogs, and humans make the concepts easy to understand.
The match-the-following questions or MCQ in this set are based on Chapter 6 of the Class 8 NCERT Science book. The questions below are designed to help you revise important topics like internal and external fertilisation, oviparous and viviparous animals, and asexual reproduction methods like budding and binary fission. Test your knowledge, spot patterns, and have fun learning! It’s like a quiz game but with science facts!
