A vörös algák (red algae) are a group of marine plants known for their reddish color, which comes from the pigment phycoerythrin. They primarily thrive in warm, shallow waters and can be found in various oceanic environments. These algae play a crucial role in marine ecosystems, providing habitat and food for many marine organisms. In addition to their ecological importance, vörös algák are also used in various industries. They are harvested for their carrageenan, a thickening agent commonly found in food products, cosmetics, and pharmaceuticals. Their unique properties make them valuable for both environmental and commercial applications.
