Water rises in plants primarily by cohesion-tension. Which of the following is not true about the cohesion-tension model?
A) Water loss (transpiration) is the driving force for water movement.
B) The "tension" of this model represents the excitability of the xylem cells.
C) Cohesion represents the tendency for water molecules to stick together by hydrogen bonds.
D) The physical forces in the capillary-sized xylem cells make it easier to overcome gravity.
E) The water potential of the air is more negative than the xylem.
Terrestrial plants and animals can be characterized by analogous pathways for water gain and loss.
