|
Active Transport |
Uses energy (ATP) to move substances across membrane |
|
|
Passive Transport |
Does not require energy to cross cell membrane Uses diffusion and filtration |
|
|
Hypertonic |
Solute is more concentrated outside the cell than inside it |
|
|
Diffusion |
Particles move in random manner, spreading evenly throughout an available space and moving from regions of high concentration to those of low concentration |
|
|
Osmosis |
Diffusion of water Molecules moving from an area of high water concentration to low water concentration |
|
|
Filtration |
Movement of water and solutes through the membrane by fluid or hydrostatic pressure |
|
|
Isotonic |
The solute concentration of the water is the same as that inside the cell |
|
|
Hypotonic |
Solute concentration outside the cell is lower than that inside the cell |
