Tranport Flashcards
1
Q
Diffusion
A
Movement of Particles from an area of higher concentration to am area of lower concentration
2
Q
Osmosis
A
Movement of water from a more dilute solution to a more concentrated solution (partially permeable membrane)
3
Q
Active Transport
A
Movement of particles
From an area of low concertation to a area of higher concentration
Using energy from respiration
4
Q
Passive transport
A
Transport that doesn’t take energy
5
Q
Concentration gradient
A
A concentration gradient occurs when the concentration of particles is higher in one area than another
