The entry of water from salty soil into roots of halophytes takes place because the root of halophytes develops:
Correct answer: C. Low water potential
- A. High water potential
- B. Low osmotic pressure
- C. Low water potential
- D. All of these
Explanation
Water potential is a measure of the free energy of water in a system and determines the direction of water movement. It is influenced by factors such as pressure, solute concentration, and gravity. Water tends to move from areas of higher water potential to lower water potential, following the path of least resistance.

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.
