Description
Moss spore capsule, polarised light micrograph. Longitudinal section through a spore capsule from a fire moss (Funaria hygrometrica). The capsule's cover is dark green at its base (apophysis), where photosynthetic tissue makes food for the developing spores. The inner capsule (upper centre) is where the spores form. The inner capsule has a lid (operculum, pink), with edges (annulus, bright green) that break down to allow the lid to fall off, releasing the spores. Magnification: x45 when printed at 10 centimetres high.
