Question

Quizplus · Accepted Answer

The passage of materials across cell membranes is influenced by concentration (gradient), size (of molecules or ions), and charge, among other factors. Concentration gradients drive diffusion, size affects the ability of molecules to pass through membrane pores, and charge influences the movement of ions across membranes.
