9. Differentiate between the following:-
(ii) liverworts and moss
Differences between liverworts and mosses are as follows
Liverworts | Mosses |
Sporophyte has very little photosynthetic tissue, so it is completely parasitic on the gametophyte | Sporophyte contains more photosynthetic tissue |
Scales often present | Scales are mostly absent |
Gemma cups are present for vegetative reproduction in some liverworts | Gemma cups are mostly absent |
Rhizoids are unicellular | Rhizoids are multicellular |
The gametophyte is thalloid with dichotomous branching | The gametophyte is leafy, branching is lateral |
Chlorophyll and stomata are absent. | Chlorophyll and stomata are present in sporophytes for gaseous exchange. |
