osmosis & tonicity
The movement of any substance directly through the cell membrane with no energy
Diffusion
Osmosis does not need this to occur
ENERGY
In these solutions there is a higher concentration of water INSIDE the cell than OUTSIDE the cell
Hypertonic
In these solutions there is a higher concentration of water OUTSIDE the cell than INSIDE the cell
Hypotonic
The diffusion of water across the membrane using no energy and a specialized pore, aquaporin, is called
Osmosis
This describes the membranes ability to control what enters and exits the cell
Semi-permeability
In a hypertonic solution the cell
Shrinks
In a hypotonic solution the cell
Swells
A solution with a higher SOLUTE concentration that the inside of a cell is_______.
hypertonic because there is less water in the solution
A solution with a lower SOLUTE concentration than the inside of a cell is _________.
hypotonic because there is more water in the solution
The shrinking of a plant cell exposed to a hypertonic solution is called
plasmolysis
When an animal cell is placed in a hypotonic solution and absorbs too much water _________happens.
plasmolysis
