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.
