NCERT Solutions for Class 12 Biology Chapter 1 Reproduction in Organism: It’s true that whatever has come to this earth it has to die after a certain time of period without any fail. So, have you ever assumed that how the species of any organism survive years to years? So the answer to this question is Reproduction. It becomes a vital process without which species cannot survive for long. Each individual leaves its progeny by asexual or sexual means. And through reproduction species continue to live through millions of years unless threatened by natural or anthropogenic extinction.

In NCERT Class 12 of Biology Chapter 1 Reproduction in Organism, you will learn different types of reproduction that is asexual reproduction and sexual reproduction. Asexual reproduction does not involve the fusion of gametes. It is common in organisms that have a relatively simple organisation such as the fungi, algae and some invertebrate animals. And sexual reproduction involves the formation and fusion of gametes. It is a complex and slow process as compared to asexual reproduction. Most of the higher animals reproduce almost entirely by the sexual method.

This figure represents the asexual reproduction in different organisms through budding, fusion, etc.

Here are the important topics of Class 12 Biology Chapter 1 Reproduction in Organism:

1.1 Asexual Reproduction

1.2 Sexual Reproduction

  1.2.1 Pre-fertilisation Events

        1.2.1.1 Gametogenesis

        1.2.1.2 Gamete Transfer

  1.2.2 Fertilisation

  1.2.3 Post-fertilisation Events

        1.2.3.1 The Zygote    

        1.2.3.2 Embryogenesis

In NCERT Class 12 Biology Chapter 1 Reproduction in Organism you will also learn that prokaryotes and unicellular organisms reproduce asexually by cell division or binary fission of the parent cell. Reproduction in Organism will tell you about so many important terms related to the reproduction like clones, gametes, syngamy, embryogenesis, etc.

After going through the Class 12 Biology Chapter 1 Reproduction in Organism of NCERT you can easily answer a few of the important questions like:

  • Q1. Why is the offspring formed by asexual reproduction referred to as clone?
  • Q2. How does the progeny formed from asexual reproduction differ from those formed by sexual reproduction?
  • Q3. Difference between gametogenesis from embryogenesis.
  • Q4. Why are the offspring of oviparous animals at a greater risk as compared to offspring of viviparous animals?

And if still confused then Solutions for NCERT Class 12 Science of Chapter 1 - Reproduction in Organism is there for you.
