Morning glory pollen grains. Coloured scanning electron micrograph (SEM) of pollen grains (orange balls) on the pistil (female reproductive part) of a morning glory flower (Ipomoea sp.). Pollen grains contain the male gametes (sex cells) of a flowering plant. Once the pollen has landed on the pistil,the male gametes travel to the ovaries where they fertilise the female gametes (ovules). Magnification: x52 at 6x7cm size | |
