Lemna (genus)

Lemna is a genus of small aquatic plants commonly known as duckweeds. These tiny, floating green plants are among the simplest and fastest-growing flowering plants, often covering water surfaces like ponds and lakes. Lemna species play important roles in aquatic ecosystems by providing food for wildlife, aiding water purification, and contributing to oxygen production. Their rapid reproductive cycle allows them to form dense mats, helping to stabilize water environments. Despite their simplicity, Lemna plants are studied for potential uses in wastewater treatment, biofuel production, and as a sustainable protein source.
