Cherry blossom pollen. Coloured scanning electron micrograph (SEM) of pollen grains from a cherry tree flower (Prunus yedoensis). The outer wall (exine) of each grain is highly sculptured to improve its adherence to pollinating insects. Each grain of pollen contains a male gamete (reproductive cell) that is intended to fertilise an egg or ovule (female gamete) and initiate the formation of a seed for a new plant.
