Diffusion
What is the movement of molecules from an area high concentration to an area of low concentration?
Isotonic
The cell in the picture is sitting in what type of tonic solution?
hypotonic
The cell in the picture is sitting in what type of tonic solution?
Hypertonic
The cell in the picture is sitting in what type of tonic solution?
Selective Permeability
Cell membrane allows certain molecules to cross it depending on size
Passive Transport (Diffusion)
Requires no energy to move molecules from high to low concentration
Active Transport
Requires energy and carrier proteins to move molecules from low to high concentrations
Osmosis
Diffusion of water
Isotonic Solution
Concentration of the solutes on both sides of the membrane are equal
