pollen grains photographed with an electron microscope
Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). 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 gymnosperms.

Pollen grains from a variety of plants. Pollen grain size, shape and surface texture differ from one plant species to another. The pollen grains contain a male gamete (reproductive cell) that is intended to fertilise an egg or ovule (female gamete). This will initiate the formation of a seed for a new plant.
