Morphological adaptations in roots of hydrophytes

Explanation

Morphological adaptations in roots of hydrophytes include
Roots may be entirely absent , e.g. Wolffia,
Salvinia or poorly developed, e.g. Hydrilla.
Roots are well-developed with distinct root caps, e.g. Ranunculus (emergent hydrophytes), aerenchyma present.
In Eichhornia, root caps are replaced by root pockets.
Some plants, i.e. Jussiaea have two types of roots, one is normal type and other is spongy and negatively geotropic.
