Cactus pollen grain, SEM

Cactus pollen. Coloured scanning electron micrograph (SEM) of a pollen grain of an Echinopsis sp. cactus. Pollen grains contain male gametes, which fertilize the ovules of a plant, initiating the formation of plant seeds. The outer wall (exine) of a pollen grain is highly sculpted in many plants, which may assist in their dispersal by adhering to pollinating insects. The structure of the exine is used to identify pollen from different plants. Magnification: x1100 when printed 10cm wide

Cactus Exine Flowering Plant Gamete Pollen Grain Re Production Reproductive Sexual Spike Spikes Spiky Succulent Wall


EDITORS COMMENTS
This print showcases the intricate beauty of a cactus pollen grain. Taken using a scanning electron microscope (SEM), the image reveals the vibrant colors and detailed structure of this tiny reproductive element. The Echinopsis sp. cactus pollen grain contains male gametes, essential for fertilizing plant ovules and initiating seed formation. One striking feature is the highly sculpted outer wall, known as exine, which serves multiple purposes in many plants. In addition to providing protection, this textured surface aids in dispersal by adhering to pollinating insects. Furthermore, scientists can use the unique exine structure to identify pollen from different plant species. At a magnification of x1100 when printed 10cm wide, every minute detail becomes visible—showcasing nature's remarkable design at its finest. The spiky appearance adds an extra layer of intrigue to this already fascinating subject matter. This photograph not only highlights the wonders of botany but also emphasizes the importance of sexual reproduction in flowering plants like cacti. It serves as a reminder that even within seemingly harsh environments such as deserts, life finds ingenious ways to propagate and thrive. Science Photo Library has once again captured an awe-inspiring moment from nature's vast repertoire—a testament to their dedication in bringing scientific marvels closer to our eyes without compromising on quality or accuracy.
