Chapter 10 in Science deals with the topic of 'How do organisms reproduce'. This chapter primarily discusses the reproductive system in living organisms and the types of reproductive systems, in particular. It shows the different methods of reproductive systems in plants and animals and distinguishes between asexual reproduction and sexual reproduction.

Class 10 Science Chapter 8 notes further elaborates on the male reproductive system and the female reproductive system.

FAQ (Frequently Asked Questions)

1. What is Fission in Reproduction?

Ans. Fission, as discussed in How do organisms reproduce Class 10 notes, is the separation of a single body into two new bodies by duplication of the genetic material of the organism. In the process of fission, deoxyribonucleic acid undergoes division to form two parts. The second process is termed as cytokinesis. Binary fission is an example of asexual reproduction and organisms falling under Bacteria and Archaea exhibits this type of reproduction process.

2. What are the Benefits of Vegetative Propagation?

Ans. The most prominent advantages of vegetative propagation have been outlined in Class 10 Science Chapter 8 notes. One of the major benefits is that the new plants will retain the genetic material of a single parent. It means that if specific desirable traits have been identified in the parent plant, the same will be replicated in the offspring as well. However, for that to happen, growing conditions have to be kept the same.

Notes of Chapter 8 Science Class 10 also mentions that in the case of vegetative propagation, the immature seedling phase is bypassed. Such development helps in reaching the mature phase faster.

3. What is Meant by Spore Formation?

Ans. Spore formation has been explained lucidly in Class 10 Chapter 8 Science notes. It is a process of asexual reproduction exhibited by plants such as moss, ferns, fungi etc.

Spores are essentially reproductive bodies which are unicellular. Those are present in a sac-like structure known as sporangia. On attaining maturity, spores burst out from sporangia and transmitted to various places with the help of wind, air or water.

4. What is the Function of Pollination in Plant Reproduction?

Ans. Ch 8 Class 10 Science notes discuss pollination as the procedure of transmitting pollen from the male part of a flower, anther, to the female part of a flower, stigma. However, it must be noted in this regard that such happens between a male part of one flower to the female part of another flower. With pollination, a seed is produced from fertilised flowers, leading to the formation of fruit.
