The pollen for each kind of tree or flower is distinctive to that species, so there is no definite description for what pollen in general looks like - the grains aren't even all round; the size also varies: for instance, a grain of pollen from an elm tree (which is round) is about 20 micrometers in diameter, whereas a pollen grain from a Scots pine tree is kinda kidney shaped, & measures about 40 x 60 micrometers
