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:
“In my public statements I have earnestly urged that there rested upon government many responsibilities which affect the moral and spiritual welfare of our people. The participation of women in elections has produced a keener realization of the importance of these questions and has contributed to higher national ideals. Moreover, it is through them that our national ideals are ingrained in our children.”
—Herbert Hoover (1874–1964)
“A man’s personal defects will commonly have with the rest of the world precisely that importance which they have to himself. If he makes light of them, so will other men.”
—Ralph Waldo Emerson (1803–1882)
““I’m sure you’ve often wished there was an after-life.” Of course I had, I told him. Everybody has that wish at times. But that had no more importance than wishing to be rich, or to swim very fast, or to have a better-shaped mouth.”
—Albert Camus (1913–1960)
