Pollen

3.


The picture above shows pollen on my nail. Pollen grains contain the male DNA of a plant. The grains are produced by division of mother cells along the inner edges of a plant's anthers, which are sac-like structures that sit atop long filaments in a flower's center.
Flowering plants depend on pollen for fertilization and reproduction. The pollen is carried from flower to flower by the wind and insects.
