Turgor pressure air pressure with water
Same as air pressure to a tire
Osmosis water goes into sell (low salt to high salt areas)
Gives plants its rigidity
Driving force of growth
Wilting Lose turgor and plant becomes droopy due to plasmolysis of individual cells
Translocation movement of water up stems, up through the xylem
Woody stem goes up sap wood of xylem
Recognize sap wood by whiter color. Dark wood hard wood.
Transpiration sweating
2 ways to move water
Push and pull (suck or push it)
Positive water pull it
