Question

During phase of cell enlargement in plant growth, solute concentration favours ______________.

• A. endosmosis
• B. plasmolysis
• C. imbibition
• D. exosmosis

Hint:

Endosmosis increases turgidity, which is essential for cell expansion.

Answer 1

The Correct Option is A

Step 1: Understanding cell enlargement.
Cell enlargement in plants occurs mainly due to the uptake of water into the vacuole, which increases turgor pressure.
Step 2: Role of solute concentration.
Higher solute concentration inside the cell lowers the water potential of the cell sap.
Step 3: Movement of water.
Water enters the cell from the surrounding medium through a semi-permeable membrane, a process known as endosmosis.
Step 4: Conclusion.
Therefore, solute concentration during cell enlargement favours endosmosis.
