Passive Transport Flashcards
Solute
A solid substance that dissolves in a liquid substance
Solvent
The liquid that the solute dissolves in
Solute concentration
The amount of solute dissolves in a solvent
-Goes from an area of high concentration to areas of low solute concentration
Passive Transport
Methods of transporting materials into and out of the cell that DO NOT require energy
Diffusion
The movement of molecules from a hypertonic area to a hypotonic area
(Moves along the concentration gradient)
Osmosis
Specialized type of diffusion involving the movement of water in or out of the cell
Moves from a high to low area of concentration.
Facilitated diffusion
The movement of larger molecules across the cell membrane with the help of an embedded transport protein
High to low area of concentration
