Germinating plane tree pollen. Coloured scanning electron micrograph (SEM) of a plane tree (Platanus sp.) pollen grain that has sprouted a pollen tube (red). Pollen contains the male sex cells of a plant. Pollen tubes are produced when a pollen grain lands on the pistil (female part) of a flower. The tube burrows down into the pistil to reach the ovaries, where it fertilises the ovum (egg cell).
