Pollen, like on this Gerbera, is a fine powder consisting of pollen grains, which carry the male gametes of seed plants. The transfer of pollen grains to the female reproductive structure can be mediated by the wind, in which case the plant is described as wind-loving, these plants typically produce great quantities of very lightweight pollen grains. Insect-loving plants produce pollen that is relatively heavy and sticky, for dispersal by insect pollinators attracted to their flowers. Photo credit: pdphoto.org |
