Reproductive organs of a lily flower
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

EDITORS COMMENTS
This print showcases the intricate reproductive organs of a stunning hybrid Tango lily Cappuccino. Lilies, as monocotyledonous plants, exhibit an enchanting three-fold symmetry in their floral parts. The image beautifully captures the essence of these delicate flowers. In this snapshot, we can observe six vibrant orange anthers that serve as the pollen-bearing structures. Each individual pollen grain represents a microspore containing the male gametophyte of the plant. Moving towards the center, our attention is drawn to the columnar style culminating in a mesmerizing mauve-hued stigma. This stigma also possesses three-fold symmetry and features a sticky surface. The significance of this sticky stigmatic surface becomes apparent upon contact with compatible pollen grains. When such grains come into contact with it, they germinate and produce long pollen tubes that penetrate through its surface. These tubes then grow down along the column until reaching the ovary below, effectively conveying the male gametophyte to an ovule for fertilization. This extraordinary process exemplifies nature's remarkable ability to ensure reproduction in plants like these lilies. As garden enthusiasts or admirers of botanical wonders, we can appreciate both their aesthetic beauty and scientific complexity captured within this striking photograph from Science Photo Library's collection on reproductive organs and pollination mechanisms in flowering plants.
