movement in and out of cells Flashcards
1
Q
what is diffusion
A
the net movement of molecules from high concentration region to low concentration region, down the concentration the gradient, until an equilibrium is reached
2
Q
how to speed up diffusion
A
the diffusion distance is short, bigger difference between in the concentration
3
Q
What is osmosis
A
the net movement of water molecules from high water potential region to low water potential region, down a water potential gradient, through partially permeable membrane
4
Q
plant cell is flaccid when there is _____ water potential in the cell.
A
low
5
Q
what is active transport
A
moving molecules from low concentration region to high concentration region, against the concentration gradient, using energy from respiration and protein carrier in the membrane
