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)
“There is much to be said in favour of modern journalism. By giving us the opinions of the uneducated, it keeps us in touch with the ignorance of the community. By carefully chronicling the current events of contemporary life, it shows us of what very little importance such events really are. By invariably discussing the unnecessary, it makes us understand what things are requisite for culture, and what are not.”
—Oscar Wilde (1854–1900)
“There are of course people who are more important than others in that they have more importance in the world but this is not essential and it ceases to be. I have no sense of difference in this respect because every human being comprises the combination form.”
—Gertrude Stein (1874–1946)
