Macrophotograph of a section through the ovary of a hyacinth flower, Hyacinthus orientalis. Pollen is brushed onto the rough-surfaced stigma by visiting insects. A pollen grain germinates producing a pollen tube which grows down the short style into the ovary. The male gamete passes down the pollen tube to one of the ovules (the white, rounded structures seen within the ovary) which it fertilises. The fertilised ovule develops into a seed. Hyacinths can also reproduce asexually, by vegetative propagation. Magnification: when printed at 10 centimetres wide.
