Plant cells do not burst when placed in hypertonic solution because of:
Correct answer: C. Cell wall
- A. Vacuole
- B. Cell membrane
- C. Cell wall
- D. All of these
Explanation
The correct answer is Cell wall. Plant cells are surrounded by a rigid cell wall that provides structural support and prevents the cell from bursting when exposed to different osmotic conditions. In a hypertonic solution, water moves out of the cell, but the cell wall maintains the cell's integrity and shape. The vacuole helps with turgor pressure but does not prevent bursting. The cell membrane is semi-permeable and regulates substance passage but does not provide the structural support needed to prevent bursting. Therefore, only the cell wall is responsible for this specific function.

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.
