Sexual Reproduction in Flowering Plants: The Development of Pollen

The video explains the development of male gametophytes starting in the anthers of flowers. It details the formation of pollen sacs containing diploid microspore mother cells, which undergo meiosis to produce haploid microspores. These microspores then undergo mitosis to form pollen grains, each consisting of a generative cell and a tube cell. The video also describes how pollen grains are released and attach to the stigma of flowers, aided by their distinctive outer walls.
