Need nutrients (energy, oxygen, water, essential nutrients) Die at varying rates; replenish themselves every 3, 10, 120 days or once every few years (i. e. rbc every 3-4 months, need iron and b12) gi replace the quickest, so harmful substances get rid of. Each cell contains a complete set of genes; different ones are active in different types of cells. Grouped together to form tissues & organs; organs work together in body systems: fat cells. Specialize to store fat in the adipose tissue: red blood cells.
