Lily pollen grains. Spectral-Rheinberg light micrograph of pollen grains from the Lily plant (family Liliaceae). Pollen grains contain male gametes. When the pollen lands upon the female stigma of another Lily flower, the pollen grain germinates. A tube grows out of the pollen grain through the stigma; the male nuclei pass down this tube and fuse with the female ovules. A zygote is formed which develops into a seed.
