|
water potential
|
Dilute solution (where there is a lot of water) has a high water potential and a concentrated (where there is less water) has a low water potential
|
|
|
water potential gradient
|
water flows down the gradient from high water potential to low water potential
|
|
|
turgid
|
when a plant cell is blown up like a tire
|
|
|
flaccid
|
when the cell becomes floppy, and it begins to wilt
|
|
|
plasmolysed
|
if a solution is very then a lot of water will diffuse out of the cell the cytoplasm and vacuole go on shrinking. As the cytoplasm shrinks further into the cell the cell wall gets left behind. the cell membrane, surrounding the cytoplasm tears away from the cell wall
|
|
|
Active transport
|
An energy consuming process by which substances are transported against the concentration gradient
|
|
|
Carrier proteins
|
pick up nitrate ions from the outside of the cell and then change shape in such a way that they push the nitrate ions through the cell membrane and into the cytoplasm of the cell
