Decreases - 22How do cells get around the limits of the surface to volume ratio?1. Divide
2. Become multicellular
3. Get long and thin
4. Fold - 23Three ways to increase the rate of Diffusion1. Increase temperature
2. Increase concentration
3. Decrease size of molecules - 24Osmotic pressurePressure due to the flow of water from where the solution has less solute to where to solution has more solute in it.
- 25Isotonic solutionSolutions that contain the same number of solute molecules per volume ad the cell.
- 26Hypertonic solutionA greater number of solute molecules per volume.
- 27Hypotonic solutionA lesser number of solute molecules per volume than the cell.
