Question

Which of the following statements are true about transpiration?

Select all that apply

For transpiration to occur, cohesion between water molecules must be overcome.

Several different processes work together to enable transpiration to take place.

Transpiration moves only small quantities of water through a plant.

Transpiration moves water from a plant’s roots to its stem and leaves.

Answer 1

True:
- Several different processes work together to enable transpiration to take place.
- Transpiration moves water from a plant’s roots to its stem and leaves.

False:
- For transpiration to occur, cohesion between water molecules must be overcome. (Cohesion is essential to the cohesion–tension mechanism that pulls water up the xylem; local evaporation breaks some bonds at the leaf surface, but overall cohesion is required.)
- Transpiration moves only small quantities of water through a plant. (Plants transpire large volumes of water daily.)
