The advantages of vegetative propagation are

1. It is a cheaper, easier and more rapid method of propagation in plants than growing plants from their seeds.
2. Plants which do not produce seeds can be propagated by this method.
3. The new plants are exact copies of the parent plant.

1. The process by which an organism gives birth to young ones of its own kind is called reproduction. 
2. Reproduction is essential for continuity of species.

1. The transfer of pollen from the anther to the stigma of a flower is called pollination.
2. The two types of pollination are self-pollination and cross-pollination.
3. If the pollen lands on the stigma of the same flower or when the pollen of a flower lands on the stigma of another flower of the same plant it is called self-pollination. When pollen lands on the stigma of a different flower on another plant but of the same species, it is called cross-pollination.

1. To prevent overcrowding.
2. To avoid competition for sunlight, water, and minerals.
3. To invade new habitats.

1. After fertilization, the ovary grows into a fruit.
2. The seeds develop from the ovules.
3. The other parts of the flower fall off.

Explanation: 1 Mark each
Following are the different parts of a flower:
a)Sepal- The green leafy part of a flower that protects the flower during the bud stage.
b)Petal- The bright, colourful part of a flower that attract insects for pollination.
c)Stamen- The male reproductive part of a flower. Stamen has two parts - anther and filament. Anther produces the pollen grains.
d)Pistil- The female reproductive part of a flower. It has three parts - stigma, style and ovary. Ovary contains the ovule which produces the egg cells.
