Which one of the following will happen if the medium surrounding the cell has a higher concentration than the cell?

The cell will gain water
The cell will die
There will be no change
The cell will lose water

The correct answer is (d). The cell will lose water.

When the medium surrounding the cell has a higher concentration than the cell, it is said to be hypertonic. In this case, water will move from the cell to the medium, causing the cell to shrink. This can lead to cell death if the cell loses too much water.

Option (a) is incorrect because the cell will lose water, not gain water.

Option (b) is incorrect because the cell will not necessarily die. It will only die if it loses too much water.

Option (c) is incorrect because there will be a change in the cell. The cell will shrink.

I hope this helps!
