Charophytes

Charophytes are a group of algae that are believed to be the closest living relatives of land plants. They are significant because they provide a better understanding of the early evolutionary events that led to the transition from aquatic to land plants. Charophytes are used to understand global ecosystems because they are the primary producers in many freshwater ecosystems, and their productivity is important for maintaining water quality. In addition, they are important for bioremediation as they can uptake and assimilate nutrients and toxins from polluted aquatic ecosystems.
