Description
Hollyhock pollen. Colored scanning electron micrograph (SEM) of pollen grains of the hollyhock, Althaea rosa. The outer wall (exine) of each pollen grain has a spiky structure; these surface projections may serve to adhere the pollen to insect pollinators. The pollen is tranferred to the stigma of the flower, where it fertilizes the ovules in the female ovary to form seeds. Hollyhock is a herbaceous and medicinal plant with white, pink, red or purplish flowers. The pollen may play a role in allergic reactions. Magnification x202 at 6x6cm size.
