Surface Area |
Volume ration decreases as the size of any three-dimensional object increases. |
|
|
Diffusion |
The net movement of molecules or ions from a region of higher concentration to a region of lower concentration down a gradient, as a result of the random movements of particles. |
|
|
Facilitated Diffusion |
The diffusion of a substance through transport proteins in a cell membrane. The proteins provide hyprophilic areas that allow the molecules or ions to pass through the membrane which would otherwise be less permeable to them. |
|
|
Osmosis |
The net movement of water molecules from a region of higher water potential to a region of lower water potential, through a partially permeable membrane, as a result of their random motion. |
|
|
Active Transport |
The movement of molecules or ions through transport proteins across a cell membrane, against their concentration gradient, using energy from ATP. |
|
|
Endocytosis |
The bulk movement of liquids (pinocytosis) or solids (phagocytosis) into a cell, by the infolding of the cell surface membrane to form vesicles containing the substance. |
Endocytosis |
|
Exocytosis |
The bulk movement of liquids or solids out of a cell, by the fusion of vesicles containing the substance with the cell surface membrane. |
