Question

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

Answer 1

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.  

Answer 2

Answer:

The correct option is A.

Which is cell A will swell more than cell B.

Explanation:

1. As the cells have same concentrations.
2. So when they put in different solutions, Cells A in 2% glucose will lose less water due to osmosis than cells B which are in 5% glucose solution.
3. Hence cells A will be more swell than cells B.
