Liverwort spore capsule, light micrograph
Liverwort spore capsule, light micrograph. Longitudinal section through the thallus and sporangium of a liverwort (Jungammania sp.) The sporangium (spore capsule, centre) is enclosed within the thallus case (calyptra). The sporangium is full of spherical spores, but between these are elongated cells with spiral thickening (elaters). When the sporangium splits open these elaters twist around as they dry and flick out the spores, which are then carried away by air currents. Magnification: x105 when printed at 10 centimetres high

EDITORS COMMENTS
This print showcases the intricate beauty of a Liverwort spore capsule, captured under a light microscope. The image reveals a longitudinal section through the thallus and sporangium of a liverwort species known as Jungammania. At the center of attention is the sporangium, also referred to as the spore capsule, enclosed within its protective case called calyptra. The sporangium appears filled with numerous spherical spores; however, amidst them are elongated cells adorned with spiral thickening structures known as elaters. These specialized cells play an essential role in dispersing the spores into their surroundings. As the sporangium splits open, these remarkable elaters twist around while drying out and swiftly flick out the spherical spores. Carried away by air currents, these tiny reproductive units embark on their journey to propagate new liverwort plants. With magnification at x105 when printed at 10 centimeters high, this photograph allows us to marvel at nature's intricacy on both macro and micro scales. It offers insight into plant anatomy and highlights various biological aspects such as cellular structure and reproduction processes specific to bryophytes like liverworts. Displayed against a white background, this stunning image from Science Photo Library serves as a testament to botanical wonders that often go unnoticed by our naked eyes but hold immense significance in understanding our natural world's complexity.
