Moss spore capsule. Coloured scanning electron micrograph (SEM) of the mouth of a capsule (spore case) of a moss. Mosses reproduce by means of spores (small blue spheres) which are dispersed from the mouth of the capsule by the numerous rays (orange and brown) that snap open. Each capsule is borne on a spiralling stalk that is coiled up in dry weather and unrolls only in damp conditions.
