Question

give technical term for a medium which has same concentration as the cell . why does the size of the cell remain the same when placed in such a solution

Answer 1

The medium which has exactly the same concentration as the cell is known as isotonic solution. The size of the cell remains the same,when it is placed in isotonic solution because the amount of water going in the cell is equal to the amount of water going out of the cell,hence there is no overall movement of the cell.
