Explain how materials enter and leave cells
WebCells carry out chemical reactions that are essential for organism survival. The substance needed for the reactions have to get into the cells and waste products must be removed from the cells. Websoluble molecules pass between the phospholipids to enter or leave the cell, moving from areas of high concentration to areas of low concentration (they move down their concentration gradient). Oxygen and carbon dioxide and most lipids enter and leave cells by simple diffusion. Illustrations of simple diffusion.
