Term
Hypertonic
Definition
Solution has more particles and less water causing water to flow out of cell and cell to shrink.
Term
Hypotonic
Definition
Solution has less particles and more water causing water to flow into cell.
Term
Isotonic
Definition
There is a balance in particles and water molecules within solution and cell.
Term
Crenation
Definition
A process resulting from osmosis in which cells, in a hypertonic solution, shrink and acquire a scalloped surface.
Term
Lysis
Definition
A process resulting from osmosis in which cells in a hypotonic solution, swell and can burst.
Term
Solute
Definition
A particle or substance that is dissolved within another substance.
Term
Diffusion
Definition
PARTICLES moving from an area of HIGHER concentration TO LESSER concentration.
Term
Osmosis
Definition
WATER moving from an area of HIGHER concentration of water TO LOWER concentration of water
Term
Active Transport
Definition
When proteins cross cell membrane going AGAINST GRADIENT (going from low to high); requires energy to complete this transport - uses ATP.
Term
Selective Permeability
Definition
When a membrane allows some molecules to pass through but not others; depends on charge, size and lipid soluability.
