Aquatic plants are plants that have adapted to living in saltwater or freshwater environments they are also referred to as hydrophytes or macrophytes.
Hydrophytes: hydrophytes are aquatic plants that are especially suitable for alive in aquatic Environments. a hydrophyte is also known as an aquatic macrophyte, whichever completely Submerged in water or in some cases float on the surface of the water
Aquatic plants are four main types
deep water plants
In rivers macrophytes cover for fish and substrate for aquatic invertebrates, produce oxygen, and food for some fishes and wildlife.
Aquatic plants require special variations for living submerged in water, or at the water's surface. The most common variation is aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is always saturated with water. They are therefore a mutual component of wetlands
Some aquatic plant functions are:
1. The production of oxygen, they oxygenate the water via plant processes through photosynthesis
2. Providing underwater cover for fish, amphibians, birds, insects and many other organisms
