FoundationWhich cells directly regulate the opening of a stomatal pore?
Need a small nudge?

The pore and the cells surrounding it have different names.

UnderstandingWhat is transpiration?
Need a small nudge?

Think of liquid water ultimately leaving a leaf as vapor.

ApplicationOn a hot, dry afternoon, a plant closes many stomata. What paired effect is most directly expected?
Need a small nudge?

The same pore is a pathway for water vapor out and carbon dioxide in.

InterpretationWhich sequence best represents the cohesion–tension pathway in a transpiring plant?
Need a small nudge?

Begin where water evaporates and trace the pull through xylem.

ConnectionA plant has intact roots and xylem but keeps its stomata nearly closed for several days. Which summary best predicts the combined outcome?
Need a small nudge?

Combine the two consequences of stomatal closure with the role of transpiration.
