Answer to Question #188737 in Biology for Enyonam

Question

how do the marchantia species discharge spores

Answer 1

Spores are produced within a capsule by meiosis. As the capsule dries, it transversely ruptures from the apex into irregular size lobes. The spores are discharged by hygroscopic movements of elaters. The spores once released are dispersed by air currents and, once they settle somewhere moist, germinate.
