Morning glory stigma and pollen, SEM
Morning glory stigma and pollen. Coloured scanning electron micrograph (SEM) of the stigma (brown) of a morning glory flower (Ipomoea sp.), with pollen grains (orange). The stigma is part of the female reproductive structure (pistil), which is formed from one or more carpels. Each carpel possesses a stigma, with a style and an ovary (not seen). The stigma is covered in projections known as papillae. These trap the pollen grains, which contain the male sex cells. If the male cells fertilise the female sex cells (ovules) in the ovary, the carpel may ripen to produce a fruit containing seeds. Magnification: x270 at 6x7cm size

EDITORS COMMENTS
This print showcases the intricate beauty of morning glory stigma and pollen. Taken using a scanning electron microscope (SEM), the image reveals the stunning details of this flower's reproductive structure. The brown stigma, part of the pistil or female reproductive organ, is prominently displayed in this photograph. It is covered with numerous papillae, small projections that serve as traps for pollen grains. The vibrant orange pollen grains are scattered across the surface of the stigma, representing male sex cells. These tiny particles contain genetic material that can fertilize ovules within the ovary, leading to fruit production and seed formation. The magnification level of 270x at a size of 6x7cm allows us to appreciate every minute detail captured in this image. From its scientific significance to its aesthetic appeal, this photograph highlights both the complexity and elegance found within nature. Whether you're fascinated by botany or simply drawn to visually striking images, this SEM print offers a unique glimpse into one aspect of plant reproduction. With its vivid colors and precise focus on each element involved in pollination, it serves as a reminder of how interconnected and awe-inspiring our natural world truly is.
