Active Transport |
The movement of chemical substances. |
|
|
Concentration Gradient |
A difference in concentration of a substance across a distance. |
|
|
Cell Membrane |
If possible full episode that covers the cell surface and acts as a barrier between inside of a celland its environment. |
|
|
Diffusion |
The movement of particles from regions of higher density and regions of lower density. |
|
|
Endocytosis |
The process by which a cell membrane surrounds a particle and encloses the particle in a vasicle to bring the particle into a cell. |
|
|
Equilibrium |
A state that exists when the concentration of a substance is the same through a space. |
|
|
Exocytosis |
A substance is related from the cell through a vasicle that transports the substance to the cell surface and fuses with the membrane to let the substance out. |
|
|
Facilitated Diffusion |
The transport of a substance through a cell membrane along a concentration gradiant with the aid of carrier proteins. |
|
|
Fluid Mosaic Model |
Describes the structure of cell membranes. |
|
|
Hypersonic |
Describes a solution whose solute consentration is higher than the solute concentration inside the cell. |
|
|
Hydroponic |
Describe the solution who silent concentration is lower than the solute concentration inside the cell. |
|
|
Isotonic |
A solution who smell the concentration is equal to the solute concentration inside the cell. |
|
|
Osmosis |
Diffusion of water or another Sheldon from more dilute solution to a concentrated solution through a membrane that is permeable to a solvent. |
|
|
Passive Transport |
The movement of a substance across the cell membrane without the use of energy by the cell. |
|
|
Phagocytosis |
The ingestion of bacteria or other material by phagocytes and amoeboid protozoans. |
|
|
Phospholipid |
The lipid that contains phosphorus and that it is structural component in a cell membrane. |
|
|
Receptor |
The protein that brings specific single molecules, which continues the seller to respond. |
|
|
Selective Permeability |
All cells are enclosed within a cell membrane. |
|
|
Vasicle |
A fluid - or air - filled cavity or sac, in particular. |
