Land plants have life cycles in which a haploid gemetophyte generation alternates with a diploid sporophyte. In spiral mosses (Bryopsida sp.), the gametophyte is the dominant generation which is rarely the case in other species, and the sporophyte grows from the tip of a gametophyte. Sporocytes consist of a sporangium and a stalk. The Sporangium (or capsule) contains thousands of tiny spores which are released and distributed by the wind, after the lid dries, shrinks and springs open.
Note: this is the worlds largest color Scanning-Electron-Micrograph. The original print measures 250cm x 150cm (100 x 60in) and is available in a limited edition of only 3 pieces (one still available).
