Importance
Root hairs form an important surface over which plants absorb most of their water and nutrients. They are also directly involved in the formation of root nodules in legume plants
They have a large surface area, this makes absorbing both water and minerals more efficient using osmosis. Also, root hair cells secrete acid (H+ from malic acid) which exchanges and helps solubilize the minerals into ionic form, making the ions easier to take up.

Famous quotes containing the word importance:
“I am not sure that it is of the first importance that you should be happy. Many an unhappy man has been of deep service to himself and to the world.”
—Woodrow Wilson (1856–1924)
“We ought to esteem it of the greatest importance that the fictions which children first hear should be adapted in the most perfect manner to the promotion of virtue.”
—Plato (c. 427–347 B.C.)
“We have been told over and over about the importance of bonding to our children. Rarely do we hear about the skill of letting go, or, as one parent said, “that we raise our children to leave us.” Early childhood, as our kids gain skills and eagerly want some distance from us, is a time to build a kind of adult-child balance which permits both of us room.”
—Joan Sheingold Ditzion (20th century)
