How does the surface to volume ratio of a cell affect the rate of diffusion of materials across the cell’s surface?

WHat do the terms "freely permeable" or "impermeable mean with respect to the cell membrane? What would happen to the cell in either case?

How does the rate of diffusion and surface-to-volume ratio limit cell size?

Component Function: b) Movement of solutes across a membrane occur with the help of transport protein. i) Name the disease due to defective carrier proteins that transport cystine. i) Name and describe one (1) type of gated ion channel. i) Explain how glucose molecules are transported across plasma membrane into a cell via passive transport.
