Lemnaceae, commonly known as duckweeds, is a family of small, floating aquatic plants found in freshwater environments. These plants are characterized by their tiny, leaf-like structures and rapid growth, often forming dense mats on the water's surface. Duckweeds play a crucial role in ecosystems by providing habitat for various organisms and helping to improve water quality. This family includes several genera, such as Lemna and Spirodela, which are important for studies in ecology and environmental science. Due to their fast growth and ability to absorb nutrients, duckweeds are also explored for use in wastewater treatment and as a sustainable food source for livestock and aquaculture.
