Knowra Aquatic plant Aquatic plant An aquatic plant is adapted to live submerged in water, float at its surface, or grow in waterlogged soil. Its structures and life cycle suit persistent access to water.
Aerenchyma : A plant tissue with air-filled spaces that facilitate internal gas movement and can aid buoyancy. Its air channels carry oxygen to submerged roots and stems.
Emergent plant : A wetland plant rooted underwater or in saturated soil, with stems or leaves rising above water. Emergent species bridge aquatic and terrestrial conditions along shorelines.
Constructed wetland : An engineered wetland designed to treat water or provide other ecosystem functions. Planted wetland systems use aquatic vegetation to retain nutrients and pollutants.
Seagrass meadow : A shallow marine ecosystem formed by flowering plants rooted in underwater sediment. Seagrass meadows show how aquatic plants create extensive habitat and store carbon.
Hydrophyte : A plant adapted to growing in water or persistently waterlogged environments. This broader ecological term groups plants by adaptation to wet habitats.
Wetland : An ecosystem where water saturates or covers the soil for part or all of the year. Wetlands provide the waterlogged soils and shallow waters many aquatic plants inhabit.
Phytoremediation : The use of plants to remove, contain, or transform contaminants in soil or water. Some aquatic plants accumulate or transform pollutants in contaminated waters.
Freshwater ecosystem : An ecosystem of rivers, lakes, ponds, or other inland waters with low salinity. Aquatic plants provide food, shelter, and structure across freshwater habitats.
Aquatic plant morphology : The structural features of plants adapted to submerged, floating, or emergent growth. Thin leaves, reduced support tissue, and flexible stems suit aquatic conditions.
Hydroperiod : The seasonal pattern, duration, and frequency of flooding at a site. Flood timing determines which aquatic growth forms can persist in a habitat.
