Types Of Transport Flashcards
1
Q
Diffusion
A
When materials move from an area of high concentrations to an area of low concentration down a concentration barrier with no energy.
E.g. Gases,liquids or dissolved substances
2
Q
Osmosis
A
Water molecules move from high concentration to an area of low concentration across a selectively permeable membrane
3
Q
Active transport
A
When the movement of molecules moves from a low concentration to an area of high concentration up a concentration barrier with energy
4
Q

A
Process of particles moving though a solution or gas with an area of higher number of particles to an area with a lower number of particles.
