Pollen consists of one or more vegetative cells and a reproductive cell. A pollen grain itself is not the male gamete. In angiosperms and certain gymnosperms, the vegetative cell forms the pollen tube that grows to meet the unfertilized ovules, and the reproductive cell is the source of the sperm.

Basically, pollen is a sperm delivery system. If a pollen grain “gets lucky,” that is, it meets the flowers or cones of its species, it germinates, creating little tubes to deliver the sperm to the ovule, which is the female gametophyte. That’s plant sex, in a nutshell.

What is the transfer of powdery pollen called?

Pollination
Pollination is simply the transfer of pollen grains from an anther to a stigma. Fertilization occurs much later when the pollen grains germinate on the stigma and send down a pollen tube which releases the sex cells to fertilize the ovules.

Many people have an adverse immune response when they breathe in pollen. The immune system normally defends the body against harmful invaders — such as viruses and bacteria — to ward off illnesses. In people with pollen allergies, the immune system mistakenly identifies the harmless pollen as a dangerous intruder.
