Characteristics and Examples of Hydrophytes

Hydrophytes are well adapted to aquatic environments. Some morphological character  of hydrophytes : Roots may be absent (Wolffia, Utricularia) or poorly developed (Hydrilla). Roots, if present, are mostly concerned with Anchorage (Ranunculus). Root caps are replaced by toot-pockets (Eichhornia, Pistia) In some cases floating roots may develop in addition to normal roots  (Jussiaea). The submerged parts […]
