An artificial cell consisting of an aqueous solution enclosed in a selectively permeable membrane (but with no cell wall) is immersed in a beaker containing an aqueous solution. The outside environment concentration consists of 0.01 M glucose and the inside of the cell has a concentration of 5.0 M glucose. The plasma membrane is permeable to water and monosaccharides, but impermeable to the disaccharides. Complete the following for the image below: Will the artificial cell become lyse, shrivel, or stay the same? lyse shrivel stay the same

As given the question, the artificial cell has a higher glucose concentration than the surrounding environment. A concentration gradient is produced by this difference in concentration, and it encourages water molecules to enter the cell through osmosis. Until the concentration of glucose is the same on both sides of the plasma membrane, water moves across the membrane from an area of lower solute concentration (outside the cell) to an area of higher concentration (inside the cell).
