Enumerate the morphological adaptations of Hydrophytes. 
by

1 Answer

Answer :

Ans: 

1. Roots are either absent (Wolffia, Ceratophyllum) or poorly developed (Hydrilla). Rooted hydrophytes have root caps but not others. Free floating hydrophytes may have Root pockets as in Pistia and Eichhornia. Balancing roots are seen in free floating hydrophytes. 

2. Stem may be long and slender as in submerged forms like Hydrilla and Potamogeton. Offsets are seen in free floating forms. Rhizome is seen in rooted hydrophytes with floating leaves like Nymphaea and Nelumbo. 

3. Leaves are ribbon like in Vallisneria, linear in Potamogeton, finely dissected in Ceratophyllum, large and flat with flexible elongated petioles, having waxy coating on the upper surface in Nymphaea, Victoria, Nelumbo. Swollen and spongy petioles in Eichhornia and Trapa.
