DIFFUSION VS BULK FLOW

Question 1

Transpiration

Answer 1

evaporation of water mainly through the stomata of leaves

Question 2

Surface tension (σ)

Answer 2

enhancement of intermolecular attractive forces at the surface

Question 3

Fick’s law

Answer 3

describes the movement of water by diffusion
Area, gradient and distance

Question 4

Diffusion is faster when

Answer 4

The concentration gradient dc/dx is steeper, the area A is larger, the distance x is smaller

Question 5

stomata

Answer 5

Stomata closed= water potential=0
Stomata open= water potential <0 air-water-interface is curved
