Pollen grains from different plants, conputer illustration. Pollen grain size, shape and surface texture differ from one plant species to another, as seen here. The outer wall (exine) of the pollen in many plant species is highly sculpted which may assist in wind, water or insect dispersal. This pollen sculpting is also used by botanists to recognise plant species. Pores in the pollen wall help in water regulation and germination. These reproductive male spores produced by seed plants contain the male gametes. Pollen fertilises the female egg, with subsequent formation of plant seeds.

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.

Pollen grains within a Stellaria graminea anther. The anther is the pollen-bearing body of the stamen, which is the male part of flowering plants. S. graminea is a species of flowering plant in the Caryophyllaceae family, known commonly as lesser stitchwort and grass-like starwort. The herb is a common plant of waysides, hedgerows and open woodlands. Coloured scanning electron micrograph (SEM), magnified x200 when printed at 10cm wide.
