    Inside the anther, pollen mother cells (microsporangia) divide by meiosis to form pollen grains which are contained in pollen sacs. When pollen is ripe the pollen sacs open and pollen grains are dispersed by the wind or animals.

    Once the pollen lands on an appropriate receptive stigma, the pollen grain germinates and a long tube grows down into the ovary, in the tube two sperm cells travel to fertilize the receptive flower.

    Pollen is not the same as sperm, but is a vehicle that transports and protects the sperm.

    Pollen comes from trees and flowers.For example did you ever go outside and see these trees covered in white type of flowers that is where pollen comes from.

    Pollen is formed from diploid microspore mother cells that undergo meiosis to produce four pollen grains from each mother cell.
