Question

Assume a living cell with 0.9% (\(w/w\)) of glucose solution (aqueous). This cell is immersed in another solution having equal mole fraction of glucose and water. (Consider the data up to first decimal place only) The cell will:

• A. Shrink since solution is 0.5% (\(w/w\))
• B. Shrink since solution is 0.45% (\(w/w\)) as a result of association of glucose molecules (due to hydrogen bonding)
• C. Show no change in volume since solution is 0.9% (\(w/w\))
• D. Swell up since solution is 1% (\(w/w\))

Hint:

In osmosis, water moves from areas of low solute concentration to high solute concentration. If the concentrations are equal, there is no net movement of water.

Answer 1

The Correct Option is C

The question involves osmosis, where water will move in or out of the cell based on the concentration of solute in the surrounding solution. The solution with the same concentration of glucose (0.9% \(w/w\)) inside and outside the cell will have the same osmotic potential, meaning there will be no net movement of water into or out of the cell. 
Hence, the cell will show no change in volume, as the concentration of glucose inside and outside is equal.
