One of the largest aquatic plants in the world is the Amazon water lily; one of the smallest is the minute duckweed. Many small aquatic animals use plants like duckweed for a home, or for protection from predators, but areas with more vegetation are likely to have more predators.quatic plants can only grow in water or in soil that is permanently saturated with water. They are therefore a common component of wetlands. The principal factor controlling the distribution of aquatic plants is the depth and duration of flooding.
