When cavitation blocks passage of water, it is called an embolism. One mechanism by which plants can repair an embolism is by producing positive pressure from the root (pushing water up the xylem). When do you think it is the best time for this mechanism to take place?Group of answer choicesAt night, when there is low or no transpirationEarly in the day, when there is lig

Step 1
Transpiration is the process by which water is lost from a plant to the atmosphere as water vapor. It is primarily driven by sunlight and temperature, which cause the stomata (pores in the leaf) to open and release water vapor. Show more…

During what time of day is a plant at greatest risk for the formation of air bubbles in the xylem stream?
Cavitation can occur when what happens? Gas bubbles expand inside a tracheid or vessel member. Root pressure pushes water up the xylem. Stomata get stuck closed. Starch grains block the sieve tubes. Clouds block sunlight shining on the leaves.

"Root pressure theory" proposes that water from roots is pushed up a stem. Although root pressure sometimes occurs, it does not account for all xylem flow. What evidence would you look for to determine whether water in xylem moves under tension or pressure?
