Fern sorus. Fluorescence light micrograph of a sorus on the underside of a fern frond. A sorus is a cluster of spore-producing receptacles called sporangia (blue and green) on the underside of a fern frond. Each sporangium is packed with spores, which are the fern's reproductive cells. A rim of thick-walled cells, the annulus (green), functions to open and rapidly close each sporangium when the spores are mature, releasing them into the environment. Magnification: x64 when printed at 10cm wide.
