When a cell is placed in a solution whose osmotic concentration is equal to cell sap then:

1. Water moves inside the cell.

2. Water moves outside the cell.

3. No net movement of water occurs.

4. Cell will be plasmolysed.

What will be the direction of flow of water when a plant cell is placed in a Hypotonic solution?

1. Water will flow in both directions.

2. Water will flow out of the cell.

3. Water will flow into the cell.

4. No flow of water in any direction.

During plasmolysis:

1. Water is lost from the cytoplasm but not from the vacuole

2. Water is first lost from the cytoplasm and then from the vacuole

3. Water is first lost from the vacuole and then from the cytoplasm 

4. Water is lost from the vacuole but not from the cytoplasm 

What happens, when a cell is placed in a isotonic solution?
(a) There is not net flow of water towards the inside or outside.

(b) Cells are said to be flaccid.

(c) ${\psi }_P$ becomes positive.

(d) Enlargement and extension growth of cells occur.

The correct statement(s) is/are

1. a only

2. a and b only

3. a, b and c only

4. all are correct
