The imаge belоw represents а cоntаiner оf water with a cell in it. The cell has a selectively permeable membrane. The membrane is permeable to water and glucose but not to sucrose. The concentration of glucose and sucrose inside and outside the cell is represented by M. The higher the number, the higher the concentration. Use the image below the answer the following questions. Place your answer after the question. a. Will glucose diffuse across the membrane? If so, which way? b. Will sucrose diffuse across the membrane? If so, which way? c. Is the cell in an hypotonic, isotonic, or hypertonic solution? d. Will the cell shrink, shrivel, or stay the same shape?
