Dandelion pollen. Coloured scanning electron micrograph (SEM) of a pollen grain from the dandelion,Taraxacum officinale. The pollen grain is spined and finely-sculpted in shape,with a porous surface. Each species of flowering plant has pollen of a unique structure and shape. Pollen can be dispersed by the wind,or by insects such as bees. Spines on pollen grains,as seen here,often helps the pollen to attach to insect pollinators. The dandelion produces yellow flowers and hairy seeds,and is a common weed throughout Europe.
