Which of the following describes a phenomenon that occurs when we observe plants that wilt? a. the plant begins absorbing oxygen and releasing carbon dioxide into the atmosphere. b. the roots begin to rot, causing them to no longer uptake water. c. the xylem releases all its water. d. the stomata close, cutting off transpiration and gas exchange.

The xylem releases all its water when we observe plants that wilt.

Option C

Explanation:

Wilting is a process where the plant loses its rigidity and droops down. To understand it better the water is absorbed through the roots and aids in the functioning of the plant. The excessive water is stored inside the vacuole when during water scarcity releases water.

But during the drought conditions the water is lost completely causing the leaves to shrink. The xylem starts releasing all its water leaving a less surface area. Hence the leaf shrinks and wilting occurs.
