Liverwort spore capsule,polarised light micrograph. Longitudinal section through the thallus and sporangium of a liverwort (Pellia epiphylla). The sporangium (spore capsule,upper centre) is enclosed within the thallus case (calyptra),surrounded on either side by two lamellae. Below the sporangium is a cylindrical tube (the seta). The sporangium is densely packed with spherical spores,which are carried away by air currents when the sporangium splits open. Magnification: x14 when printed at 10 centimetres high | |
