Coloured variable pressure scanning electron micrograph (SEM) of the base of a Mexican orange (Choisya ternata 'Aztec Pearl') stigma. Three pollen grains (yellow) are adhered to the ovarian complex. The stigma is part of the plant's female reproductive organs. Pollen grains are a plant's male gametes (sex cells). Stomata (air pores, bright green) can be seen in the stigma walls. | |
