Describe how root hairs absorb nitrate ions from soils with low nitrate concentrations?

active transport is used. The root hair cells have carrier proteins in their cell membranes.

They cannot be absorbed by diffusion , because the minerals are in very low concentration. Instead, active transport is used. The root hair cells have carrier proteins in their cell membranes. These pick up the mineral ions and move them across the membrane into the cell against the concentration gradient .
