Study Notes

Reproduction in Plants

  • All living organisms grow old and eventually die, but the species continues through reproduction.

Modes of Reproduction

  • Reproduction can be divided into two categories: asexual and sexual.

Asexual Reproduction

  • A single individual gives rise to a new organism.
  • Asexual reproduction occurs when conditions are favourable for proper growth and development.

Sexual Reproduction

  • Two individuals or cells of separate sexes are required to give rise to a new organism.
  • The male parent produces male gametes, and the female parent produces female gametes.
  • The male and female gametes fuse to form a zygote.

Natural Vegetative Propagation

  • Some plants, like mango, reproduce with the help of seeds.
  • Some plants are regenerated from leaves or stems.
  • In some plants, like onion and garlic, bulbs (underground food storage organs) produce smaller buds that give rise to a new plant.
