LIVER CELL BRAIN CELL MUSCLE CELL
Different cells with different structures and functions

4. TISSUE
A group of cells that are specialized in a certain way to perform a function. The cells that make up the smooth muscle tissue of the stomach are specialized to work together to contract the stomach and aid in digestion.

6. This specialization allows the cells to be more efficient
This specialization allows the cells to be more efficient. Instead of wasting energy expressing proteins they do not need, the express what is necessary to perform it’s function.
