Morning glory pollen grains, SEM
Morning glory pollen grains. Coloured scanning electron micrograph (SEM) of pollen grains from a morning glory flower (Ipomoea sp.). The grains have a highly sculptured outer wall (exine), which assists its dispersal by improving its adherence to pollinating insects. The characteristic surface of a pollen grain is used by botanists to recognise and classify plants. Each pollen grain contains a male gamete (reproductive cell) that is intended to fertilise an egg or ovule (female gamete), and initiate the formation of a seed for a new plant

EDITORS COMMENTS
This print showcases the intricate beauty of morning glory pollen grains. Taken using a scanning electron microscope (SEM), the image reveals the vibrant colors and highly sculptured outer walls (exine) of these tiny reproductive cells. The unique structure of the exine assists in their dispersal by enhancing adherence to pollinating insects, ensuring successful pollination. Botanists rely on such characteristic surface features to identify and classify different plant species. Each pollen grain contains a male gamete, or reproductive cell, which plays a crucial role in fertilizing an egg or ovule – the female gamete – ultimately leading to seed formation and new plant growth. The false-colored SEM image not only captures the biological essence of these pollen grains but also highlights their importance in plant reproduction. It serves as a reminder of nature's remarkable intricacy and diversity. This stunning photograph is part of Science Photo Library's collection, showcasing its commitment to capturing scientific wonders through artful imagery. It offers viewers an opportunity to appreciate both the aesthetic appeal and scientific significance found within even microscopic elements of our natural world.
