Which of the following is true regarding the classes of Bryophytes?
1. The thallus of mosses is dorsiventral and closely appressed to the surface
2. In the life cycle of liverworts, the predominant gametophytic stage is divided into two stages - the protonema and the leafy stage
3. The sporophyte in liverworts is more elaborate than in mosses
4. Asexual reproduction in liverworts takes place by fragmentation of thalli, or by the formation of specialised structures called gemmae
