Caption: Flower of the hybrid Tango lily Cappuccino showing the reproductive organs. Lilies are monocotyledonous plants with three-fold symmetry in the floral parts.The picture shows 6 anthers (orange), which are the pollen-bearing structures. Each pollen grain is a microspore containing the male gametophyte of the plant. To the centre, the columnar style terminates in the stigma (mauve hue), also of three-fold symmetry. The stigmatic surface is sticky. On contact with this surface, a compatible pollen grain germinates to produce a long pollen tube which penetrates the surface, grows down the column to the ovary below, and conveys the male gametophyte to an ovule, effecting fertilisation.
