NCERT Solutions for Class 10 Science, Chapter 8 - How do Organisms Reproduce

In this chapter, you’ll study reproduction in organisms. As ‘reproduction’ is not one of
the most essential life processes as compared to nutrition, respiration or excretion, the
basic question that arises is why organisms reproduce? The obvious answer is to
continue life on earth! Without reproduction, all organisms will become extinct one day.
Though reproduction is a cumbersome process, still it is necessary for the continuation
of life on this planet. There are different ways of reproduction depending upon the type
of organism. In NCERT Solutions for Class 10, Science, Chapter 8, you’ll get in-depth knowledge about How do Organisms Reproduce.

Let’s take a look at topics and sub-topics of Class 10 Science Chapter 8, How do Organisms Reproduce?

8.1.1 The Importance of Variation
8.2 Modes of Reproduction used by Single Organisms
8.2.1 Fission
8.2.2 Fragmentation
8.2.3 Regeneration
8.2.4 Budding
8.2.5 Vegetative Propagation
8.2.6 Spore Formation
8.3 Sexual Reproduction
