Caption: 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.
