Where does pollen come from?
This fertilizes the female reproductive cells so that a fruit or seeds will develop. Pollen is produced in flowers in the stamens and then must be transferred to the pistil, the female reproductive organ. Pollination may occur within the same flower, which is called self-pollination.
How to tell if pollen is dusting?
If not, you likely notice it dusting surfaces, often giving things, like your car, a greenish tinge. Pollen grains are unique to the plants they come from and can be identified under a microscope by shape, size, and the presence of surface textures.

Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anther of a flower to the stigma of the same flower. Pollen is infrequently used as food and food supplement.
How many microspores are produced in a diploid cell?
In a process called microsporogenesis, four haploid microspores are produced from each diploid sporogenous cell (microsporocyte, pollen mother cell or meiocyte ), after meiotic division. After the formation of the four microspores, which are contained by callose walls, the development of the pollen grain walls begins.
What happens when pollen lands on a female cone?
If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail.
What happens to the unicellular microspores during microgametogenesis?
During microgametogenesis, the unicellular microspores undergo mitosis and develop into mature microgametophytes containing the gametes. In some flowering plants, germination of the pollen grain may begin even before it leaves the microsporangium, with the generative cell forming the two sperm cells.
What is the hard coat of pollen?
Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of coniferous plants.
What is the name of the enzyme that breaks down the callose wall?
The callose wall is broken down by an enzyme called callase and the freed pollen grains grow in size and develop their characteristic shape and form a resistant outer wall called the exine and an inner wall called the intine. The exine is what is preserved in the fossil record.
