Which part of a cell allows nutrients and other materials to enter or leave the cell?
Transport proteins allow nutrients to enter and leave cells. Transport proteins are peppered throughout the cell membrane. Most molecules need the transport proteins to enter or leave the cell, but it's possible for some molecules, like water, to diffuse through the membrane by osmosis.
