Family Characeae is a type of green algae that is widely known for its unique branching pattern and cylindrical cells. This family is also commonly referred to as stoneworts, due to their tendency to secrete calcium carbonate and create a rock-like structure when they die. Some synonyms for Family Characeae include charophyte, stonewort family, and Charales. The family is known to have a widespread geographical distribution and can be found in both freshwater and brackish environments. Charophytes are also considered to be important bioindicators of water quality, as they are sensitive to pollution and changing environmental conditions. Overall, Family Characeae is an essential component of aquatic ecosystems and plays a significant role in maintaining ecological balance.
