Sharing or posting any content from this assignment, or using such shared or posted assignment content to answer assignment questions, is a violation of the Virginia Tech Honor Code.Lesson Objectives:1.Calculate the water potential of a cell and predict the direction of water movement based on water potential.3.Explain the cohesion-tension theory of water transport in the xylem.4.Describe the mechanism of stomatal opening and closing5.Explain the pressure-flow hypothesis of fluid transport in the phloem.S1. Apply scientific reasoning to biological problemsS3. Interpret and draw conclusions from scientific dataS4. Apply basic quantitative methods to biological problemsPart I: Water Potential(3.5 pts; 0.5 pts per cell) Fill in the missing data in the table and predict the direction of water movementbased on water potentials.Solutepotential ofcellPressurepotential ofcellWaterpotential ofcellSolutepotential ofsolution intowhich thecell is placed(in an opencontainer)Direction ofwater movement(into or out ofcell, or no netmovement?)-0.7 MPa0 MPa1. -.07 *(-.7)-0.9 MPa2. out -0.7 MPa0 MPa-0.7 MPa0 MPa3. in-0.35 MPa0.2 MPa4. -.15-0.15 MPa5. no net movement-0.1 MPa6. 0.05-0.05 MPa
