Summary Chapter 8 Class 10 Science

  • Reproduction, unlike other life processes, is not essential to maintain the life of an individual organism.
  • Reproduction involves 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 that 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.
  • Reproduction in flowering plants involves the transfer of pollen grains from the anther to the stigma which is referred to as pollination. This is followed by fertilisation.
  • Changes in the body at puberty, such as increase in breast size in girls and new facial hair growth in boys, are signs of sexual maturation.
  • The male reproductive system in human beings consists of testes that produce sperms, vas deferens, seminal vesicles, prostate gland, urethra and pen!s.
  • The female reproductive system in human beings consists of ovaries, fallopian tubes, uterus and vag!na.
  • Sexual reproduction in human beings involves the introduction of sperm in the vag!na of the female. Fertilisation occurs in the fallopian tube.
  • Contraception to avoid pregnancy can be achieved by the use of condoms, oral pills, copper-T and other methods.
