Transpiration Flashcards
(4 cards)
1
Q
Tranpiration
A
The loss of water vapour from the leaves via. evaporation
2
Q
Adhesion
A
Hydrogen bonding between polar water molecules and non-polar cellulose in xylem vessel walls pulls water upwards through the xylem
2
Q
Cohesion
A
Hydrogen bonding causes water molecules to stick together and move as one continuous column
3
Q
Transpiration pull
A
Evaporation of water at leaves creates the transpiration pull, and this tension is transmitted down the whole water column due to cohesion
