Chapter Review:


  • The production of new individuals from their parents is known as reproduction.
  • Most plants have roots, stems and leaves. These are called
    the vegetative parts of a plant.
  • The modes of reproduction  (i) Asexual reproduction (ii)  Sexual reproduction. 
  • A sexual reproduction in which plants are obtained from seeds.
  • A asexual reproduction in which plants can give rise to new plants without seeds. 

  • There are several methods of asexual reproduction such as
    fragmentation, budding, spore formation and vegetative propagation.

  • The small bulb-like projection coming out from the yeast cell is called
    a bud.

  • The stamens are the male reproductive part and the pistil is the female reproductive part of the flower.

  • The flowers which contain either only the pistil or only the stamens are
    called unisexual flowers.

  • The flowers which contain both stamens and pistil are called bisexual flowers.

  • In sexual reproduction a male and a female gamete fuse to form a zygote.

  • The transfer of pollen from the anther to the stigma of a flower is called pollination.

  • The pollen lands on the stigma of the same flower it is called self-pollination.

  • The pollen lands on the stigma of the another flower it is called cross-pollination.

  • Pollination takes place in plants with the help of wind, water and insects.

  • The fusion of male and female gametes is called fertilisation.
