Root hairs are important.
Root hairs are thought to be important for the uptake of water and nutrients and are also believed to help to anchor the plant in the ground. It has long been postulated that without root hairs plants would die. Root hairs are also the site of entry for Rhizobium bacteria during the formation of nitrogen-fixing nodules on nodulating plants. Nodulating plants include many important legume crops and are an important site where nitrogen is fixed from the air and brought into the food chain. A growing root hair.
