Question

how is the process of fertilization take place in plant

Answer 1

The fertilization of plant takes place with process of pollination.

Answer 2

Pollen grain contains two nuclei such as generative nuclei and tube nucleus.The pollen tube develops from the pollen grain that falls on the stigma and grows towards the ovary.Along with this the nuclei in this pollen also enter the pollen tube.The generative nucleus divides in the pollen tube to form two male gametes and the tube nucleus disintegrates.

One of the male gametes that reaches the ovary through the pollen tube fuses with the egg to form zygote. The second male gamete fuses with the polar nuclei in the ovary and the endosperm is formed from it. Zygote develops into embryo and endosperm becomes the stored food needed for the embryos growth
