Rose pollen. Coloured scanning electron micrograph (SEM) of tricolporate pollen grains of a Garden Rose, Rosa sp. Pollen grains are the male sexual spores that are discharged from the male part of the flower. They contain the gamete that fertilizes the female ovule to form a seed. Rose plants are insect pollinated, relying on insects to carry the pollen to the female flower structures. Magnification: x1,000 at 5x7cm size.
