Term | Definition |
Plasma Membrane | the flexible boundary between the cell and its environment ,to allow a steady supply of nutrients to come into the cell no matter what the external conditions are. |
Diffusion | Random movement of particles from an area of higher concentration to an area of lower concentration ,eventually resulting in even distribution . |
Osmosis | The diffusion of water across a selectively permeable membrane. |
Isotonic Solution | Concentration of dissolved substances in the solution is the same as the concentration or dissolved substances inside the cell. |
Hypotonic Solution | The concentration of dissolved substances is lower in the solution outside the cell than the concentration inside the cell. |
Hypertonic Solution | The concentration of dissolved substances outside the cell is higher than the concentration inside the cell. |
Passive Transport | Movement of particles across cell membranes by diffusion or osmosis ;the cell uses no energy to move particles across the membrane. |
Facilitated Diffusion | Passive transport of materials across the membrane using transport proteins. |
Active Transport | Movement of materials through a membrane against a concentration gradient . |
Endocytosis | A process by which a cell surrounds and takes in material from its environment . |
