Pollen grains,artwork
Pollen grains. Artwork of pollen grains from different flowers. The outer wall (exine) of each pollen grain is highly sculpted to aid their dispersal. A flowering plant produces many pollen grains which need to be dispersed. This dispersal may happen as the spiky exine sticks to a pollinator such as a bee,or the grains may be dispersed on the wind. Each pollen grain contains a male gamete (reproductive cell) that is intended to fertilise the ovule or egg (female gamete) of another plant of that species,forming the seed for a new plant. High pollen levels can trigger allergic reactions such as hay fever
