Clubmoss cone, light micrograph. Transverse section through the cone (strobilus) of the clubmoss Lycopodium clavatum. The strobilus consists of a central axis (purple). Surrounding this axis are the spore capsules (sporangia, brown, 5 seen here). These burst open to release the spores. These then germinate to form gametophyte plants that continue the reproductive cycle. Magnification: x45 when printed at 10 centimetres across.
