The statements given below are incorrect. Rewrite the correct statement changing the underlined words of the statements.
Free movement of solutes in and out of the cell takes place across the cell membrance.

Answer 1

The cell wall is the outermost covering of the cell which covers the cell membrane. The cell wall is completely permeable to ordinary macromolecules. It allows free movemnt of all substances in and out of the cell. The cell membrane is selectively permeable or semi-permeable allowing only certain molecules to pass through.

Hence, the correct statement is: Free movement of solutes in and out of the cell takes place across the cell wall.
