Isotonic solution is

A cell is placed in 0.4 M solution of sugar and no change in volume of cell is found. What is the concentration of the cell sap?

1. 40 M

2. 4 M

3. 0.4 M

4. 0.20 M

To initiate cell plasmolysis, the salt concentration must be :

1. isotonic

2. hypertonic

3. hypotonic

4. atonic

The cell gets swell up, when placed in

1. Hypertonic solution

2. Hypotonic solution

3. Ultratonic solution

4. Isotonic solution

When the cell is flaccid

1. Inflow and outflow of water is in equilibrium

2. Turgor pressure of the cell is 0

3. placed in isotonic solution

4. All of the above.

What occupies the space between the cell wall and the shrunken protoplast in the plasmolysed cell?

Plasmolysis

Which one is incorrect.

ln above diagram A is having :-

(1) Hypotonic solution 

(2) Hypertonic solution 

(3) Low $\psi$w

(4) Both B & C correct
