| A | B |
| Active Transport | process reguiring energy by which cells move materials against a concentration gradient |
| Contractile Vacuole | organelle taht collects excess water from the cell then contractsd and expells the water through a plasma mem. pore |
| Diffusion | The net movement of particles from higher to lower concentration |
| Dynamic Equilibrium | condition in which there ic continous movement but no overall change |
| Endocytosis | a process in which a cell surrounds and takes in material from its movement |
| Exocytosis | expels wastes, such as indigestable bits, from the interior to the exterior environment |
| Facilitated Duffusion | the passive transport of materials across the plasma membrane by means of transport proteins |
| Fluid Mosaic Model | property of plasma mem. where in many similar molecules are free to move sidwways within their lipid bilayer |
| Hypertonic Solution | Higher concentration of a solute |
| Hypotonic Solution | Lower concentration of a solute |
| Isotonic Solution | solution in which the dissolved substances is the same as the concentration inside the cell |
| Osmosis | diffusion of water |
| Passive Transport | movement of particles that does not require energy |
| Phosphlipid | membrane lipid has a small organic section attached to a phosphate group |
| plasmolysis | loss of water resulting in the drop of turgor pressure |
| selective permeability | plasma membrane chooses what goes in and out |
| transport proteins | allow needed substances or waste materials to pass through the plasma mem. |
| turgor pressure | internal pressure found in plant cells |
