Three morphological innovations in bryophytes that helped them to be adapted for land habit are:
1. Presence of waxy cuticle which prevents loss of water.
2. Presence of root like structures called rhizoids for mechanical support and also absorption of water.
3. Presence of gametangia.
Explanation:
- Bryophytes are called as the Amphibians of the plant kingdom, because they have various land adaptations to survive on land but also depends on water for completion of its life cycle.
- They do not have vascular tissues for the conduction of water, therefore grow in moist and shady places where water is abundant.
- The presence of waxy cuticle helps bryophytes to prevent the plant tissues from drying by preventing the loss of water.
- The presence of Gametangia provides for the embryonic development which is a feature of higher land plants.
- Also the presence of root like structures called rhizoids provides mechanical support to the plant and is a feature of higher land plants.
