Question

Choose the correct answers from the alternatives given.
The free energy per mole of any substance in a chemical system is known as

• A. Osmotic potential
• B. Water potential
• C. Chemical potential
• D. Turgor pressure

Answer 1

The correct option is C Chemical potential

The free energy per mole of any substance in a chemical system is known as chemical potential. The concentration of dissolved solutes in a solution and pressure gradient determine the chemical potential water, which is the driving force for water movement in plants. Water moves from a region of high chemical potential of water to a region of low chemical potential of water until equilibrium is reached.

Hence, the correct answer is 'Chemical potential'.
