A cell with fully elastic wall is placed in hypertonic solution. What will occur?
Correct answer: C. Cytoplasm shrinks from the cell wall and undergoes plasmolysis
- A. Change in cell size and shape
- B. The whole cell will shrink
- C. Cytoplasm shrinks from the cell wall and undergoes plasmolysis
- D. Increase in cell size
Explanation
In a hypertonic solution, the concentration of solutes outside the cell is greater than that inside. Therefore, water moves out of the cell to balance the solute concentrations. This process leads to the cytoplasm shrinking away from the cell wall, a phenomenon known as plasmolysis. Consequently, the correct option is the one that describes this specific process. The other options are incorrect because they either generalize the effects of hypertonic solutions or state the opposite of what occurs (increase in size).

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
