Pollen grain surface, SEM

Pollen grain surface. Coloured scanning electron micrograph (SEM) of the surface of a pollen grain. The characteristic outer wall, or exine, 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 a pollen grain's surface. Taken using a scanning electron microscope (SEM), this coloured micrograph reveals the characteristic outer wall, known as exine, which plays a crucial role in plant recognition and classification by botanists. The vibrant orange hues bring to life the sculpted features of this biological marvel. Pollen grains are not just visually stunning; they also hold great significance in plant reproduction. Each grain contains a male gamete, or reproductive cell, intended to fertilize an egg or ovule – the female gamete – initiating the formation of a new plant seed. This image provides us with an up-close look at nature's ingenious mechanism for dispersal and propagation. The false colour technique used in this magnified image enhances our understanding of pollen structure and biology. It serves as a reminder that even on microscopic scales, nature is full of wonders waiting to be explored. Science Photo Library brings us yet another remarkable glimpse into the hidden world around us through their expertise in scientific photography. This particular photograph captures both the scientific value and aesthetic appeal found within botanical subjects like pollen grains. Let it serve as an inspiration for further exploration into the fascinating realm of plant reproduction and its vital role in sustaining life on Earth
