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

 

NCERT Solutions for Class 10 Science Chapter 8 - How do Organisms Reproduce?: Reproduction, unlike other life processes, is not essential to maintain the life of an individual organism. Reproduction involves the creation of a DNA copy and additional cellular apparatus by the cell involved in the process. Various organisms use different modes of reproduction depending on their body design. In fission, many bacteria and protozoa simply divide into two or more daughter cells. Organisms such as hydra can regenerate if they are broken into pieces.

They can also give out buds which mature into new individuals. Roots, stems, and leaves of some plants develop into new plants through vegetative propagation. These are examples of asexual reproduction where new generations are created from a single individual. Sexual reproduction involves two individuals for the creation of a new individual. DNA copying mechanisms create variations which are useful for ensuring the survival of the species. Modes of sexual reproduction allow for greater variation to be generated.

Here are the important topics of NCERT Class 10 Science Chapter 8 - How do Organisms Reproduce mentioned below:

8.1 Do Organisms Create Exact Copies of Themselves?

    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

    8.3.1 Why the Sexual Mode of Reproduction?

8.3.2 Sexual Reproduction In Flowering Plants

    8.3.3 Reproduction in Human Beings

  • 8.3.3 (a) Male Reproductive System
  • 8.3.3 (b) Female Reproductive System
  • 8.3.3 (c) What happens when the Egg is not Fertilized?
  • 8.3.3 (d) Reproductive Health

In Chapter 8 - How do Organisms Reproduce, you will also study about the male and female reproductive organisms. The male reproductive system in human beings consists of testes which produce sperms, vas deferens, seminal vesicles, prostate gland, urethra, and penis. The female reproductive system in human beings consists of ovaries, fallopian tubes, uterus, and vagina. Sexual reproduction in human beings involves the introduction of sperm in the vagina of the female. Fertilization occurs in the fallopian tube. Contraception to avoid pregnancy can be achieved by the use of condoms, oral pills, copper-T, and other methods.

After going through this chapter, you must be able to get the NCERT Solution of these questions which are mentioned below, as these questions are from NCERT.

  • Q1. What are the different methods of contraception?
  • Q2. How are the modes for reproduction different in unicellular and multicellular organisms?
