Diffusion, Osmosis, Active Transport Flashcards
1
Q
What is diffusion?
A
the movement of particles from a High concentration to a Low concentration
2
Q
How can the RATE of diffusion be increased?
A
increasing:
- difference in concentrations,
- surface area,
- temperature
3
Q
What is Osmosis?
A
the diffusion of water across a SEMI-PERMABLE MEMBRANE to balance concentrations inside and outside a cell.
4
Q
% change in mass equation
A
final mass - initial mass ÷ initial mass x 100
5
Q
What is Active Transport?
A
the movement of particles through a membrane via CARRIER PROTEINS.
