Flowering plants or angiosperms reproduce sexually by the process known as pollination. In this process, the pollen from the male anther is transferred to the female stigma. These pollens travel through the pollen tube and produce gametes which fuse with the egg in the embryo sac. This gives rise to fruit.
A few MCQs on Reproduction in Flowering Plants are mentioned below for practice. The answers are also provided for your reference.
