2. Hydrilla is a
aquatic plant.
Answers
Answer:
Hydrilla is a genus of aquatic plant, usually treated as containing just one species, Hydrilla verticillata, though some botanists divide it into several species.
Explanation:
Higher classification: Hydrocharitaceae
Scientific name: Hydrilla
Rank: Genus
Kingdom: Plantae
Order: Alismatales
Hydrilla is a hardy, fast-growing, herbaceous perennial with long, slender stems that can grow to some 7 metres (23 feet) in length. The leaves grow in pairs or in whorls of three to eight and are small, lance-shaped or oblong, and distinctly toothed.
Hydrilla is native to Asia (i.e., India, Sri Lanka, Korea) and possibly mainland Australia. Today, hydrilla is considered a cosmopolitan species – more of a super invader than a super model, this wily weed can now be found on every continent except Antarctica.
What are the economic impacts? Hydrilla also poses serious economic threats to communities surrounding infested waters. Hydrilla can reduce waterflow in canals, clogging waterways which can cause flooding, clog irrigation canals, and has the ability to damage dams and water plants.
