Germinating lily pollen, SEM
Germinating lily pollen. Coloured scanning electron micrograph (SEM) of lily (Lilium sp.) pollen grains that have sprouted pollen tubes. Pollen contains the male sex cells of a plant. Pollen tubes are produced when a pollen grain lands on the pistil (female part) of a flower. The tube burrows down into the pistil to reach the ovaries, where it fertilises the ovum (egg cell)

EDITORS COMMENTS
This print showcases the intricate beauty of germinating lily pollen. In this coloured scanning electron micrograph (SEM), we are granted a close-up view of lily (Lilium sp. ) pollen grains that have sprouted delicate, thread-like structures known as pollen tubes. These tubes play a crucial role in plant reproduction. Pollen, often referred to as the male sex cells of a plant, contains genetic material necessary for fertilization. When a pollen grain lands on the pistil, which is the female part of a flower, it triggers the production of these remarkable tubes. The purpose? To burrow down into the pistil and reach its ovaries where it can fertilize an ovum or egg cell. The vibrant yellow hue adds an artistic touch to this scientific marvel captured by a scanning electron microscope. It allows us to appreciate not only the biological significance but also the aesthetic appeal found within nature's creations. This image serves as a reminder of how plants employ various strategies for reproduction and survival. Through pollination and germination processes like those depicted here, plants ensure their continued existence and contribute to our planet's rich biodiversity. Science Photo Library has once again provided us with an extraordinary glimpse into nature's wonders through this false-coloured SEM photograph – showcasing both botanical fascination and scientific excellence without mentioning any commercial use or affiliation with any company.
