Plant produces large number of seeds. When these seeds fall down they start growing. The process by which the seeds are scattered to different place (far and wide from their parents) is called seed dispersal.
The seeds and fruits are dispersed away through various agencies like air, water and animals. Sometimes dispersal takes place by the explosion or bursting of fruits. If all the seeds of a plant were to fall at the same place and grow, there will be a severe competition for sunlight, water, mineral and space. As a result, the survival for the plants will be difficult and the plants who survive will not grow into a healthy plant.

Buds are small bulb-like projections of yeast cell.
These are asexual reproducing bodies of yeast. Diagrammatic representation of budding in yeast

The steps involved in the process of fertilisation are
(i) After pollination, pollen grains start growing into a pollen tube on the stigma passing through pistil.
(ii) The tube extends through the style and reaches to the ovules.
(iii) The pollen tube carries the male gametes called pollen grains.
(iv) Male gametes fuse with the egg (female gamete) present inside ovule and forms a zygote. This process is called fertilisation.
(v) Later zygote develops into an embryo and ovules develop into a seed.
(vi) Thus, seed carries an embryo with stored food and is covered by a hard protective covering called seed coat.

A spore-producing plant is bread mould.

The mode of asexual reproduction in which new plants are produced from roots, sterns, leaves and buds of parent plant is called vegetative propagation.

The pollen grain is carried to the pistil by pollinating agents. The pollinating agent can be wind, water, air or insect as per adaptation of the flower.

The male reproductive part is stamen and the female reproductive part is pistil.

Branch can be used to grow a new rose plant. As, rose reproduces by vegetative propagation, i.e. stem cutting method.

If the filament of Spirogyra are broken into fragments, then each fragment will develop into a new plant.

(a) Asexual reproduction is a type of reproduction in plants in which new plants are obtained from old ones without the production of seeds.
Two methods of asexual reproduction:
Vegetative Production, Spore Formation, Budding, Fragmentation (any two).
(b) Reproductive Parts of Flower:
