Pollinated flower pistil. Coloured scanning electron micrograph (SEM) of pollen (round, orange) on the stigmas (yellow) of a field pennycress (Thlaspi arvense) flower pistil. The pistil is the female reproductive part of the flower. It can be divided into several carpels with a stigma at their tips. The stigma is where pollen lands during pollination. The pollen grains are male gametes (reproductive cells) that can fertilise a female gamete to produce a seed. This requires the male gamete to travel down the style (the structure that supports the stigma) to the ovary at the base of the pistil. Magnification: x33 at 6x7cm size.
