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. |
