Question

Ovided before 4:30 PM. Late work will not be accepted. 1. A plant cell was placed into water that have Ys = 0 MPa. The plant cell's 's = -0.8 MPa and Up = +0.6 MPa. Discuss where water will move and how the cell's Ys and Yp will change with the movement of water. At equilibrium, what would happen if you add salt to the water? Explain.

Answer 1

water per water. water potential potential) distilled water =0. Water Potential - It is the potential energy of we unit volume relative to pure It is denoted 4. Y = 4cp + Ycs) (Pressure 'solute potential) The water potential for a pure Presuse potential potential _- It is the component of water potential which YP represents hydrostatic presure exerted exerted only water solute potential - It is the pressure which needs to be applied to e prevent inward flow of water across a semipermeable membrane! pressure). solution to 4s solute potential = osmotic potential = (- osmotic YSE tip Pressure potential. It occurs due to turgor pressure pressure exested by cytoplasm on Wall

co cell membrane since, water in eaker doesn't have any so turgor pressure (pressure potential) also water in beaker 4 16 = 0 (given) 4 = tepst 4 cst » Y=oto » wates potential o water potential In the cell 0.6 0.8 = -02 Ys=-0.8 tp = +0.6 4 = let yes, Caus The water mores from water potential Cy) Y cens <tewater) Water will move inside the cell till equilibrium is achieved (4=o) from high high water potential to low

lib on a) The solute potential is lowered as the concentration of solute stor rises in the cell. Here, since the water is moving inside the call cell. so, the solute potential will defreese. 6) The pressure potential is a function of turgor pressure cytoplasm so, as the water content increases due to inflow inflow of water inside the cell, the pressure potential will increase in the exerted water which is exell the cell wall by in till quilibrium is more equilibrium The water will achieved y =o. lini, As said in the question sult is added to the water D it will lower down the solutio solute perential solute potential 0 negative f = test PCP always for open water of fis) negative value Y = some As the & becomes negative negative so water will now more from cell to the beaker.

Hope you'll understand the concept. Please like. Thankyou
