Detailed explanation-1: -The flowers perform the function of sexual reproduction in plant . After fertilisation, the ovary grows into a fruit and seeds develop from the ovules.

Detailed explanation-2: -Sexual reproduction involves the fusion of male and female gametes. In vegetative propagation new plants are produced from different vegetative parts such as leaves, stems and roots. Flower is the reproductive part of a plant.

Detailed explanation-3: -Sexual reproduction in flowering plants involves the production of separate male and female gametophytes that produce gametes. The anther produces pollen grains which contain male gametophytes. The pollen grains attach to the stigma on top of a carpel, in which the female gametophytes (inside ovules) are located.

Detailed explanation-4: -The male reproductive organ (stamen) and female reproductive organ (pistil) may be present in the same flower or different flower. The pollen from stamen will be transferred to ovary present in the pistil, where fusion of gametes take place. The fusion of gametes further results in fruit formation. Q.
