1. The plasma membrane's role in homeostasis is to control what goes in and out of the cell.
2. temperature: To keep the cell from changing function.
pH, blood: To keep the cell from changing shape.
glucose levels: To keep the right amount of glucose in the cell for it to carry out its function.
water balance: To keep the cell from swelling or shrinking to much from extra water or lack of water.
3. Osmotic pressure is directly influenced by the amount of solute in the system so different concentrations in different solutions have different amounts of solute affecting the osmotic pressure.
