Pollen grains, SEM

Pollen grains. Coloured scanning electron micrograph (SEM) of pollen grains (purple) from an unidentified plant. There is great variation in the size, shape and surface texture of pollen. The outer wall (exine) is highly sculpted in many plants, as seen here, which may assist in dispersal. The characteristic surface of a plants pollen grains is used by botanists to recognise and classify species. Each pollen grain contains a male gamete, which fertilises the eggs or ovules, initiating the formation of plant seeds. Magnification unknown

Exine Gamete Gametes Grain Grains Pollen Re Production Reproductive Sculpted Sexual Spike Spikes Spiky Spines Spiny Surface

EDITORS COMMENTS
This print showcases the intricate beauty of pollen grains under a scanning electron microscope (SEM). The vibrant purple hue adds an artistic touch to these tiny reproductive structures, originating from an unidentified plant. What makes this image truly fascinating is the remarkable diversity in size, shape, and surface texture among the pollen grains. The highly sculpted outer wall, known as exine, can be observed in many plants. This unique feature likely aids in their dispersal across various environments. Botanists rely on such characteristic surfaces to identify and classify different species accurately. Each individual pollen grain contains a male gamete that plays a crucial role in fertilizing eggs or ovules within plants. This process initiates the formation of seeds and ensures successful reproduction for future generations. While the magnification level remains unknown, this SEM image provides us with a closer look at nature's intricate mechanisms of sexual reproduction. The spiky and spiny appearance of these pollen grains further emphasizes their importance in plant biology. Science Photo Library has once again captured a stunning moment from the natural world through this mesmerizing photograph print. It serves as a reminder of both the complexity and elegance found within even the tiniest components of our ecosystem.
