Root hair is a type of hair found on a plant's roots. The root hairs come into close contact with the water layer that forms between the soil particles.OsmosisDiffusion  allows water and dissolved minerals to enter the root hair. The water and minerals taken by the root hair from the soil move via the epidermis, root cortex, and endodermis before reaching the root xylem by diffusionosmosis.

 

The phloemxylem transports water, minerals, and nutrients from the soil to all plant parts. In plants, there are two types of "transport" tissues: collenchyma and parenchymaxylem and phloem. The xylem transports water and solutes from the roots to the leavesleaves to the roots. The phloem transports foodminerals from the leaves to the rest of the plant.
