Dandelion pappus, SEM
Dandelion pappus (Taraxacum officinale), coloured scanning electron micrograph (SEM). This is the top of one of the hundreds of seeds attached to a dandelion seedhead. It shows the parachute of fine hairs (radiating lines, pappus) by which the seed is lifted from the seed head and carried away by the wind. Magnification: x53 when printed at 10 centimetres across

EDITORS COMMENTS
This print showcases the intricate beauty of a dandelion pappus, captured through a scanning electron microscope (SEM). The image reveals the top view of one seed among many, delicately attached to a dandelion seedhead. What truly mesmerizes is the parachute-like structure formed by fine hairs known as pappus, which radiate outwards in perfect symmetry. These ethereal strands play a crucial role in wind dispersal, enabling the seeds to be effortlessly lifted from their source and carried away into new territories. The brown-colored details emphasize the complexity and importance of this reproductive part in the life cycle of Taraxacum officinale, commonly known as dandelions. As flowering plants or angiosperms, they rely on such mechanisms for successful reproduction. This false-colored SEM image provides an extraordinary glimpse into nature's ingenuity at work. With a magnification level of x53 when printed at 10 centimeters across, this photograph allows us to appreciate every minute detail that would otherwise go unnoticed by our naked eyes. It serves as a reminder that even seemingly ordinary plants like dandelions possess remarkable adaptations that ensure their survival and proliferation. This botanical masterpiece not only celebrates the wonders of flora but also highlights how science can unveil hidden marvels within our natural world.
