DIFFUSION VS BULK FLOW Flashcards
1
Q
Transpiration
A
evaporation of water mainly through the stomata of leaves
2
Q
Surface tension (σ)
A
enhancement of intermolecular attractive forces at the surface
3
Q
Fick’s law
A
describes the movement of water by diffusion
Area, gradient and distance
4
Q
Diffusion is faster when
A
The concentration gradient dc/dx is steeper, the area A is larger, the distance x is smaller
5
Q
stomata
A
Stomata closed= water potential=0
Stomata open= water potential <0 air-water-interface is curved
