Two cells of the same kind have close to the same concetration of substances in their cytoplasm. cell a is placed in a 2% glucose solution and cell b is placed ina 5% glucose solution. which of the following is correct? a. cell a will swell more than cell b b. cell b will swell more than cell a c. both cells will increase in size at the same rate d. both cells will decrease at the same rate

In the given case, cell A is placed in 2 % solution of glucose and cell B is placed in 5 % glucose solution. Both the solutions are hypotonic, and when a cell is placed in a hypotonic solution, then the greatest concentration of water will be outside of the cell. Therefore, water will enter the cell and occupies the central vacuole.  

However, cell B is placed in a more concentrated solution, so it will swell less in comparison to cell A, which is placed in a less concentrated solution. Hence, the correct answer is option A, that is, Cell A will swell more than Cell B.
