The facilitated diffusion of ions from the soil solution into root cells requires

Question

Quizplus · Accepted Answer

Facilitated diffusion of ions requires specific channel proteins in the membranes to allow the passage of the ions. The other options are incorrect because facilitated diffusion occurs down a concentration gradient and does not require the expenditure of ATP or cellular respiration. Additionally, the concentration of ions outside the root cells would need to be higher, not lower, than inside the cells for them to diffuse down the gradient into the cell.
