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 | |
