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.
