Lab 7- Membrane Permeability and Transport

Selective Permeability

a property that regulates

Diffusion

movement of molecules from a higher concentration to a lower concentration

Osmosis

movement of water across a selectively permeable membrane

Isotonic

solution with the same osmotic pressure as the solution to which it is compared to

Hypertonic

solution with a greater osmotic pressure than the solution it’s compared to

Hypotonic

solution with a lower osmotic pressure than the solution it’s compared to

Lysis

breakdown

Crenation

shrinking, and becomes spiky

Osmotic Pressure

pressure needed to stop osmosis

Filtration

Movement of material through a membrane as a result of hydrostatic pressure

Solute

Solvent

Active Transport

Passive Transport
