  30. STEPS IN STOMATE OPENING Sun comes up. Photosynthesis depletes CO2, stimulating proton pump enzymes. Proton pump enzyme turns on. H+ moved out of guard cells by active transport (ATP is used). K+ diffuses into cells via K+ channel enzymes. Water diffuses in to balance its concentration relative to K+ Guard cells swell and change shape.

  36. Maple sap is collected from the xylem in wood before leaves appear. Link to treemet

  37. The osmotic theory of sap flow invokes the involvement of living cells and sucrose to generate an osmotic pressure difference between fibers and vessels, which are proposed to be separated by an osmotic barrier. The secondary cell wall is an effective osmotic barrier for large molecules
