What is a Root Hair Cells job?
Root hair cell are dermal cells found on the roots of many vascular plants. Their job is to provide a greater surface area for water absorption. As transpiration pulls water up to the leaves, root hair cells have to absorb large amounts of water. The process by which root dermal cells take in water is osmosis. In order to diffuse large amounts of water, a cell obviously needs a large surface area. The root hair cells provide this needed extra surface area to absorb large amounts of water. Here’s some additional information (http://www.blurtit.com/q706816.html). This must be where the guy below me copied it from: Absorption of water and mineral salt take place mainly in the area of the root hair. Each root hair is a fine tube like out-growth of the epidermal cell. It grows in the soil particles. Hence it comes in close contact with the water present in the soil. Dissolved mineral salts are present in the soil water. Ther
