Ans.

The sporophyte generation is short-lived. It comprises a capsule which produces spores by meiosis and a stalk which holds this aloft the gametophyte. The spores once released are dispersed by air currents and, once they settle somewhere moist, germinate.

In Riccia, the dehiscence of the capsule is absent. The spores simply get free from sporogonium on death and decay of the thallus. This is a long and simple process. The sporophyte of Riccia lacks complexities and therefore is the simplest among the bryophytes.
