Scarcity of this substance may cause embolisms to form due to cavitation through pit membranes. Scholander's pressure bomb can be used to measure a "potential" named for this substance which is denoted with the letter psi. Oxygen evolution in photosystem II proceeds through (*) oxidation of this compound. Loss of this substance from a plant cell may cause turgor loss. The cohesion-tension theory explains this substance's motion through the xylem, and it is lost from leaves through transpiration. For 10 points, name this compound that plants combine with carbon dioxide to make glucose in photosynthesis, which splits it in the first step.
