Every cell has a a cell membrane and only water, oxygen, and CO2 can pass through it. The protein doorways help bring in large molecules. Waste products get sent out by the vesicles (which have there own membrane). Cells have organelles which are tiny organs in the cells. So basically the cell products are protected by the cell membrane which is made of layers of linked molecules.
