Transfer of pollen from anther to stigma

Explanation:
Pollination is the transfer of pollen from the anther to the stigma. This step is essential because it gets the male gametophyte in the right place to begin growing a pollen tube down the style toward the ovule, setting up fertilization later. Fertilisation happens when the sperm from the pollen tube fuses with an egg inside the ovule. Germination can refer to a pollen grain starting to grow on the stigma (or a seed beginning to sprout), but it’s not the transfer itself. Meiosis is the cell division that produces the haploid pollen and ovule gametes, not the transfer of pollen.
