Caption: False-colour scanning electron micrograph (SEM) of numerous pollen grains of a Pine tree, Pinus sp. . Each pollen grain comprises two wing-like, air- filled bladders joined to a coarse, granular body. The air bladders make the pollen grain more buoyant so that it can be dispersed over greater distances by the wind. Pollen (containing male sex cells) may be dispersed and settle on the stigma of a suitable host tree. In germination, a pollen tube grows out of the grain through the stigma & into the ovary. The male nuclei are conveyed down the pollen tube to fertilize the ovules & form a seed. Magnification: x520 at 6x7cm size.
