Caption: Liverwort spores, light micrograph. Transverse section through the sporangium of a liverwort (Pellia epiphylla). Part of the sporangium's outer wall is at left. The spherical spores take up most of the image. Between the spores 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: x100 when printed at 10 centimetres wide.
