In which plant cell or tissue would the pressure component of water potential most often be negative?

Question

Quizplus · Accepted Answer

The pressure component of water potential is often negative in the stem xylem due to tension created by transpiration. This negative pressure, also known as tension or suction, helps to pull water up from the roots and through the plant. In contrast, the pressure component of water potential is typically positive in cells where turgor pressure is present, such as in the leaf mesophyll cells or root cortex cells.
