WebRoots need a supply of oxygen to make ATP by aerobic respiration for active transport. The pumping of mineral ions into root hair cells creates a higher solute concentration in the roots than in the soil. This causes water to move from the soil into the root hair cells by … WebDiffusion. Diffusion is when particles spread from an area of high concentration to an area of low concentration. The molecules would move randomly, and they would eventually become evenly distributed. The particles move down the “concentration gradient” and this process takes no energy (it’s a “passive” process”).
