Adaptive features of aquatic plants:
- The tissues of stems of aquatic plants are air filled (aerenchyma tissue) which helps the plant to stand firmly and steadily in the flow of water.
- The outer surfaces of the plants are covered by cuticle to prevent excess water absorption.
- Stomata are abundant as there is no point of retaining moisture inside the plant body.
- Root system and water vascular system is not highly developed in aquatic plants as they can absorb water by each and every part of the body.
- The leaves of aquatic plants like lotus are wide and flattened to absorb maximum amount of sunlight.
