Hydrophytes

Vedclass · Answer

(C) Hydrophytes are plants that grow in water or in very wet environments. In these plants,vascular tissues (xylem and phloem) are often absent or poorly developed because water is readily available and does not need to be transported over long distances. They possess well-developed aerenchyma,which is a specialized tissue containing large air spaces. This aerenchyma provides buoyancy,helping the plants to float on the water surface,and facilitates the exchange of gases in submerged conditions.
