Fern spore capsule, light micrograph
Fern spore capsule, polarised light micrograph. Transverse section through the spororocarp (spore capsule) of the water fern pillwort (Pilularia globulifera). The capsule wall (yellow and green) surounds four cavities which contain either sporangia containing microspores (small and round), or sporangia containing macrospores (large brownish-black). The sporocarp eventually cracks open and a jelly containing the two types of spores ooze out. Magnification: x45 when printed at 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a fern spore capsule, captured under polarised light microscopy. The transverse section through the spororocarp of the water fern pillwort reveals a mesmerizing circular structure surrounded by a vibrant combination of yellow and green hues. Within this capsule wall, four cavities can be observed, each housing either microspores or macrospores contained within sporangia. The contrasting sizes and colors of these spores are truly fascinating; while the microspores appear small and round, the macrospores take on a larger brownish-black appearance. As time progresses, the sporocarp cracks open, causing a gel-like substance containing both types of spores to ooze out. At 45 times magnification when printed at 10 centimeters wide, this image allows us to appreciate the intricate details and internal structures that make up this reproductive part of a fern. It serves as a reminder of nature's complexity and diversity in plant anatomy. With its purple background serving as an enchanting backdrop for this biological marvel, this photograph not only highlights the scientific significance but also captures the inherent beauty found within plants. This stunning visual representation is courtesy of Science Photo Library - an invaluable resource for those seeking to explore and understand various aspects of our natural world.
