pol·li·nate

 (pŏl′ə-nāt′)
v. pol·li·nat·ed, pol·li·nat·ing, pol·li·nates
1. To transfer pollen from an anther of an angiosperm to (a stigma, flower, or plant).
2. To transfer pollen from a microsporangium of a gymnosperm to (an ovule, cone, or plant).

[New Latin pollen, pollin-, pollen (from Latin, fine flour) + -ate.]

pol·li·na·tion

(pŏl′ə-nā′shən)
The process by which plant pollen is transferred from the male reproductive organs to the female reproductive organs to form seeds. In flowering plants, pollen is transferred from the anther to the stigma, often by the wind or by insects. In cone-bearing plants, male cones release pollen that is usually borne by the wind to the ovules of female cones.

pollinate verb
Did You Know? When a pollen grain lands on or is carried to the receptive tissue of a pistil known as the stigma, the flower has been pollinated. But this is only the first step in a complicated process that, if successful, leads to fertilization. The pollen grain contains two nuclei—a generative nucleus and a tube nucleus. The generative nucleus divides in two to form two sperm nuclei. The tube nucleus grows down into the pistil until it reaches one of the ovules contained in the ovary. The two sperm nuclei travel down the tube and enter the ovule. There, one sperm nucleus unites with the egg nucleus, fertilizing the egg. The other sperm nucleus combines with two other nuclei that exist in the ovule. The fused nuclei then develop into the endocarp, the tissue that feeds the embryo. The ovule itself develops into a seed that is contained in the flower's ovary (which we know as a fruit). In conifers, the ovule is exposed (that is, not contained in an ovary), and the pollen produced by male cones lands directly on the ovule in female cones. Fertilization in conifers is not as quick as in flowering plants—the pollen nuclei often take as long as a year to reach the ovule.
