Cell Membrane
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.
Materials usually enter through the cell wall.
Materials enter and leave the nucleus through the selective membrane. The membrane always controls what leaves and enters the nucleus.

Materials can enter and leave the cell more easily and quickly, and the membrane can stretch and the cell expand to accomodate larger amounts of storage product. This is expecially seen in fat cells.
