Spore dispersal in Bryophytes
... Spore dispersal in Bryophytes SPORE DISPERSAL IN BRYOPHYTES The sporophyte generation is short-lived. It comprises a capsule which produces spores by meiosis and a stalk ... dispersed by air currents and, once they settle somewhere moist, germinate. This recommences the gametophyte generation. The spore first produces a filamentous stage called a protonema. These cells are full of ...
