Higher turgor pressure in a plant cell is maintained by _.
Correct answer: D. Both a and b
- A. Higher ionic concentration inside vacuoles
- B. Higher osmotic pressure of the cell vacuole
- C. Large number of vacuoles in a plant cell
- D. Both a and b
Explanation
Option D is correct.Higher ionic concentration means water does not leave the vacuole, and the higher osmotic pressure of the vacuole means the vacuole will push the cell membrane, producing pressure and a higher turgor of the plant cells that helps keep the plant steady.

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.
