Apply concept of water potential and osmosis
The pressure applied in this experiment is
(1) Hydrostatic Pressure
(2) Colloidal pressure
(3) Osmotic pressure
(4) Pressure potential
Osmotic pressure is a function of
(1) Osmotic potential
(2) Solute concentration
(3) Solvent amount
(4) Water potential
Osmotic pressure is the
(1) Pressure required to stop the water diffusing in
(2) Function of solute concentration
(3) More the solute, more is the pressure needed to stop endosmosis
(4) All of these
Numerically osmotic pressure is equal to the
(1) Osmotic potential
(2) Solute potential
(3) Both A and B but sign is opposite
(4) Pressure potential
Isotonic solution is
(1) A solution which is more concentrated than the cytoplasm
(2) A solution which is more dilute than the cytoplasm
(3) A solution which balances the osmotic pressure of the cytoplasm
(4) A solution which is less dilute than the cytoplasm
Hypotonic solution is
(1) solution which is more concentrated than the cytoplasm
(2) A solution which is more dilute than the cytoplasm
(3) A solution which balances the osmotic pressure of the cytoplasm
(4) A solution which is less dilute than the cytoplasm
Hypertonic solution is
(1) solution which is more concentrated than the cytoplasm
(2) A solution which is more dilute than the cytoplasm
(3) A solution which balances the osmotic pressure of the cytoplasm
(4) A solution which is equal to that of cytoplasm in terms of concentration
Plasmolysis
Which one is incorrect.
(1) External solution is hypertonic
(2) Water moves out of the cell
(3) Cell membrane shrinks away from it's cell wall
(4) Firstly cell sap comes out then cytoplasmic water.
What occupies the space between the cell wall and the shrunken protoplast in the plasmolysed cell?
(1) Hypertonic solution
(2) Hypotonic solution
(3) Water
(4) Cytoplasmic content
Plasmolysis is
(1) Usually reversible
(2) Occurs when cell is placed in hypotonic external solution
(3) Shrinkage of cytoplast
(4) All of these
