Two semi-permeable bags containing 2% sucrose placed in two beakers, 'P' containing water and 'Q' containing 10% sucrose. Which one of the following outcomes is true?

Osmosis is the net movement of solvent molecules into a region of higher solute concentration through a semi-permeable membrane. In the given question, one of the 2% sucrose containing bags (semi-permeable) is placed in a water-containing beaker. Clearly, the concentration in the bag is more than the beaker and as a result, water will move through the semi-permeable membrane (endosmosis) and make the bag turgid. On the other hand, the second beaker contains 10% sucrose solution which is more concentrated than the semi-permeable bag's sucrose concentration. Hence water will move out of the bag to the beaker and make the bag flaccid (exosmosis). Thus, the answer B is correct.
