NEET Biology: Cell Structure and Function questions with solutions

Q1. Choose the correct answer from the alternatives given. If a cell is placed in an isotonic solution, what will occur?

1. Salts will move into the cell from the surrounding solution
2. Water will move into the cell from the surrounding solution
3. Salts will move out of the cell into the surrounding solution
4. None of the above will occur

Answer: None of the above will occur

An isotonic solution has the same solute concentration as the cell, so water moves in and out at equal rates. Because there is no concentration gradient, there is no net movement of water or salts, making the correct choice D.
