Here are the following adaptations in bryophytes to adapt land habitat:
Multicellular plant body and conservation of water:
A compact multicellular plant body was formed which helped in the conservation of water by reducing cell surface are exposed to dry land conditions.
Absorption of CO2:
Modification of photosynthetic tissues for the absorption of carbon dioxide without losing much water and exposure to light.
Absorption of water:
Special structures like rhizoids were developed for absorption of water and anchorage.
Heterogamy was evolved, forming non-motile egg containing stored food and motile sperms.
Protection of gametes:
Gametes were produced and protected by the special multicellular organs.
Embryo formation:
Multicellular embryo was formed which was retained inside the female reproductive body during its development.
Alternation of generation:
Alternation of spore producing generation (sporophyte) with gamete producing generation (gametophyte) enables the plant to produce and test the best genetic combinations for adapting to the versatile (multipurpose) terrestrial conditions.
