Question

The statement given below is incorrect. Rewrite the statement by changing the underlined words.

Free movement of solutes in and out of the cell takes place across the cell membrane.

Answer 1

Cell wall:

1. The cell wall is the cell's outermost layer, which covers the cell membrane.
2. Cell wall is fully permeable and all the molecules can pass through it.
3. It allows all molecules to freely move in and out of the cell.

Cell membrane:

1. Cell membrane is a lipoprotein structure that is present beneath the cell wall.
2. Only specific molecules can pass through the cell membrane, which is selectively permeable or semi-permeable.
3. Hence, the correct statement is: Free movement of solutes in and out of the cell takes place across the cell wall.
