The Important Root Hairs

This picture shows a germinating seed that has thrown out roots which, even at this early stage, are provided with root hairs which, penetrating the soil, serve as mouths to take up moisture laden with nutrient salt. Root hairs, so-called, are of course not hairs in the proper sense, but tiny filaments of protoplasm with thin walls through which the nutrient solutions readily circulate. Tiny as they are, they constitute a highly important part of the mechanism of the plant.
