FAQ (Frequently Asked Questions)

Q1. What will a Student get to Learn in the Chapter of Reproduction in Organism?

Ans. This chapter of CBSE 12 comprises the topics of asexual reproduction, reproduction necessity, budding, binary fusion, fragmentation, sexual reproduction, vegetation propagation, sexual reproduction in plants and advantages of sexual and asexual reproduction.


By studying this chapter, students will get to know the processes of reproduction in detail. Moreover, this unit focuses on female and male reproductive systems, plant reproduction, contraceptive methods and fertilisation. Reproduction is essential for the progression of species on the planet. If organisms stop reproducing, there will be a discontinuity of life.

Q2. How is DNA Important in Reproduction? Is it Related to Proteins?

Ans. DNA is exceptionally vital for all living creatures on earth, even in plants. They are essential for coding for proteins, inheritance and acts as a guide of genetic instruction for life and related processes. DNA stores the information for each cell’s or a living being’s development, reproduction and finally death.


DNA holds the codes for proteins, but the real protein is different from the codes available on DNA. The fundamental steps included are transcription, translation, and at last, modification and folding.

Q3. Why is an Offspring Born from Sexual Reproduction Likely to Survive More Than Asexual Reproduction?

Ans. The mode of sexual reproduction necessitates female and male gamete fusion. During the zygote formation process, exchange of traits and genes takes place between the gametes. Similarly, during the process of chromosome segregation and crossing over, chances of elimination of non-identical characteristics are much higher. Therefore, the offspring born does not resemble its parents and hence more chances of survival. However, if the mother parent is suffering from an acute disease like AIDS, etc., the child may not survive for long.
