Free-floating hydrophytes: hydrophytes that float freely on the surface of water bodies in constant contact with air and water are known as free-floating hydrophytes. Salvinia, Wolffia, etc.
Trapa and other rooted hydrophytes have long petioles that float on the water's surface with roots embedded in the mud. Utricularia and Ceratophyllum, are two floating hydrophytes.
Rooted submerged hydrophytes: hydrophytes that are completely established in the soil and submerged in water. Hydrilla, Vallisneria, and other similar plants.
Rooted emergent hydrophytes: those that develop in shallow water and have branches that are partially or completely exposed to the air are known as rooted emergent hydrophytes.
Some plants, such as Ranunculus and Sagittaria, have a well-developed root system that is well-anchored in the soil.
