Pollen Rate.
The anther is the part of the stamen that contains the pollen grains. These pollen grains are the male reproductive cells that are essential for the process of pollination.
stamens
The pistil is the female reproductive organ of a flower. Its main function is to receive pollen grains and facilitate fertilization in order to produce seeds.
Rain can carry various pollutants such as dust, pollen, soil particles, and minerals. These particles can be carried by rain over long distances before being deposited on the ground.

Pollen Rate.
Microspore mother cell after undergoing meiosis produces pollen grains, and the pollen grains during germination produce sperms by undergoing pollen mitosis.
There is no such sense of a pollen "rate," but there is of a pollen count. Which means the average pollen grains in a cubic meter!
Pollen grains are produced by the male reproductive organs of flowering plants called anthers. Anthers contain pollen sacs where pollen grains develop and mature.
palynology
Matured pollen grains contained sperm cells. When Pollen grains are sticky, you have pollen. Pollen grains are contained in the pollen sac, with the purpose of helping plants reproduce.
The transfer of pollen grains from the stamen to the pistil is called pollination.
Pollen grains are often called as microspores or male gametes. They are produced in pollen sacs present in pollen chambers in the anthers of the flower. They are produced due to repeated division of microspore mothercells and are haploid (n).
Pollen grains
The structure where pollen grains land and stick is the stigma of a flower. The stigma is the uppermost part of the pistil, and its sticky surface helps to capture and hold pollen grains for fertilization.
