BOTANY

Detailed explanation-1: -A plant has one reason to grow – to reproduce and make more plants like it. Flowers are the reproductive parts of most plants. In order for a seed to develop, pollen has to move from male to female parts of flowers and grow down to the ovary.

Detailed explanation-2: -The process of fertilization in plants occurs when gametes in haploid conditions meet to create a zygote which is diploid. The male gametes of the flower are transferred on to the female reproductive organs through pollinators. The final product of this process is the formation of embryo in a seed.

Detailed explanation-3: -Answer : The function of a flower is to carry out sexual reproduction in plants through the formation of male and female gametes. Flowers ensure that the gametes fertilise to form seeds that further help in reproducing plants.

Detailed explanation-4: -Flowering plants have a unique process of fertilization, called double fertilization, where through the process of fertilization they produce an embryo as well as an energy pack to feed the embryo (endosperm).

Detailed explanation-5: -As a result of pollination, pollen grains are deposited on the stigma of the carpel, and it grows into a pollen tube. The Pollen tube pierces the stigma and grows through style. It enters the ovary and then ovisac through an opening called the micropyle. Pollen tube contains two male gametes.
