WebUptake of water into the root. Root hair cells are adapted for the efficient uptake of water (by osmosis) and mineral ions (by active transport); Root hairs are single-celled extensions of epidermis cells in the root; They grow between soil particles and absorb water and minerals from the soil Root hair cells vary between 15 and 17 micrometers in diameter, and 80 and 1,500 micrometers in length. Root hairs are found only in the zone of maturation, also called the zone of differentiation. They are not found in the zone of elongation, possibly because older root hairs are sheared off as the root elongates and moves through the soil.
