Description
Pollen tubes. Colored scanning electron micrograph (SEM) of pollen tubes (orange) on the pistil of a prairie gentian flower (Gentiana sp.). Pollen contains the male sex cells of a flowering plant. Once the grains land on the pistil (female parts) of a flower, the pollen grains form tubes that burrow down through the stigma (tip) and style (shaft) of the pistil to reach the ovule, which contains the ovum, the female sex cell. This is fertilized, forming a seed.
