Enkianthus flower. Coloured scanning electron micrograph (SEM) of the reproductive structures inside an Enkianthus perulatus flower. The female structure (pistil) can be seen at centre,surrounded by the male reproductive structures (stamens,pink). Pollen grains are the male sex cells of a flowering plant. When one lands on the female pistil it sprouts a pollen tube that burrows down to reach the ovary,where it fertilises the ovum (egg cell) | |
