| Term | Definition |
|---|---|
| Monomer | The smallest part of the molecule; the building block. |
| Polymer | The longer/larger molecule that is made up of smaller parts. |
| Diffusion | Particles randomly move from close together to far apart based on energy resulting in even distribution with continual motion. (Particles move from high to low concentration). |
| Osmosis | The movement of water across a barrier (a selectively permeable membrane). Water is small; easily travels; equilibrium |
| Selectively Permeable Membrane | Lets certain particles pass through the membrane easily. |
| Active Transport | Molecules which are too big to pass through SP membrane are passed through by using special structures, this takes energy. This takes low to high concentration; against the gradient. |
| Hypertonic Solution | Higher concentration of particles outside of the cell in the solution (liquid) than inside of the cell. |
| Hypotonic Solution | Lower concentration of particles outside of the cell in the solution than inside the cell. |
| Equilibrium | Particles are moving equally into the cell as they are outside of the cell. (Continual equal motion) |
| Isotonic Solution | Equal particles in solution as inside the cell. Already at equilibrium. |
| Organelles | Organized or specialized structures in the cell. Ex: Lysosomes, Mitochondrion, and etc. |
