What kind of aquatic plant is duckweed?

Duckweed is a small, floating aquatic plant belonging to the family Lemnaceae. It consists of tiny, green, leaf-like structures called fronds that can reproduce rapidly, forming dense mats on the surface of ponds, lakes, and slow-moving waterways. Duckweed is known for its ability to absorb nutrients and improve water quality, making it an important plant in freshwater ecosystems. Additionally, it serves as a food source for various aquatic animals and has potential applications in wastewater treatment and as a feed in aquaculture.
