In plants there are two modes of reproduction, asexual and sexual.
There are several methods of asexual reproduction such as fragmentation, budding, spore formation and vegetative propagation.
Sexual reproduction involves the fusion of male and female gametes..
Flowering plants, also called angiosperms, use a sexual mode of reproduction.
Reproduction in plants, mainly revolves around the flower, which has both the male and the female gametes.
All parts of a flower aid in the process of reproduction, although some of them are sterile..
Stamen consists of long and slender stalk called filament and generally bilobed anthers.
Each lobe contains two theca (dithecious).
The anther is four-sided structure consisting of four microsporangia, two in each lobes.
Microsporangia develop further and become pollen sacs which contain pollen grains.Mar 26, 2019.
Flower is the main reproductive part of the plant.
It is made up of four whorls and out of them two outer whorls are the calyx and corolla.
The inner two whorls are androecium or the male part of the flower and gynoecium or the female part of the flower..
Chapter 2 of NCERT Class 12 Biology focuses on the different parts of a flowering plant, along with the formation process and reproduction.
Students will also be familiar with the process of pollination in flowering plants where the pollen grains are transferred from one flower to another..

Flower Structure:
Flowers are reproductive structures of flowering plants.
Generally a flower consists of four whorls: 1st whorl of the calyx (sepals), 2nd of corolla (petals), 3rd of androecium (stamens), and 4th of the gynoecium (pistil)..
