Hint: The reproductive part of the plant is a flower. It consists of the male reproductive organ which is called androecium and the female reproductive organ is called gynoecium. By the fusion of the male gamete and egg cell fertilization occurs.
Complete answer:
A plant has a male part called androecium and a female part called a gynoecium.
The androecium consists of stamens. Each stamen represents the male reproductive organ and it is made up of a stalk or a filament and an anther. The anther is present at the tip of the filament and each one is bilobed. Every lobe has two chambers which are called pollen sac. The production of pollen grains takes place in pollen sacs.
Gynoecium: it is the female reproductive part, consisting of the pistil. The pistil has three parts which are stigma, style, and ovary. The ovary is the enlarged basal part on which presents an extended long tube called the style. Ovary and stigma are connected through style. Stigma is present on the tip of the style and it receives the incoming pollen grains. Each ovary consists of one or many ovules that are attached to the placenta.
The pollen grains produced in the pollen sac are released and reach the stigma by various means, this phenomenon is called pollination. After pollination, the male gametes are produced by germination which reaches the embryo sac through the pollen tube. In the embryo sac, the fusion of male gametes and egg cells occurs and the formation of zygotes occurs.
Note: Each lobe of the anther consists of the four microsporangia which develop pollen sac and finally, pollen grains are produced. The pollen grains consist of the vegetative cell and a reproductive cell, the formation of the pollen tube takes place by the vegetative cell.
