A very important group of red algae is the coralline algae, which secrete calcium carbonate onto the surface of their cells. Some of these corallines are articulated (right, Corallina, with flexible erect branches; others are crustose (below). These corallines have been used in bone-replacement therapies. very important group of red algae is the coralline algae, which secrete calcium carbonate onto the surface of their cells.
