Potato slices were placed in sucrose solution . After half an hour, density of sucrose solution increased . Water potential of Pototo tuber is

A

Equal to solute potential of sucrose solution

B

Greater then sloute potential of sucrose solutioin

C

Less then solute potential of sucrose solution

D

Half the concentration of sucrose solution

Text Solution

Verified by Experts

The correct Answer is:
C

Water potential `Psi_(omega)` and solute potential `Psi_(s)` have nagative values (less then zero ). Hero less means more negative (higher D.P.D. and higher osmotic pressure) and more means less negative (lower D.P.D. and low osmotic pressure ).

Osmotic pressure of 0.1 M sucrose solution is -2.3 bars . What is the likely osmotic potential of 0.1 M NaCl ?

Select the correct ones. A-Apoplastic movement of water occurs exclusively through cell wall. B-Solution increase free energy of water or water potential. C-Symplasric movement occurs through plasmodesmata. D- Membrane permeability depends upon membrane composition as well as chemical nature of solute

Find out the correct pair of statements (i) In completely plasmolysed cell, pressure potential does not contribute to water potential (ii) If a cell is placed in hypotonic solution for longer time , the cell membrane shrinks away from its cell wall (iii) Apoplastic system comprises interconected protoplasts (iv) Polypeptides have more imbibing capacity then polysaccharides

The decomposition of N_(2)O_(5) " in CCl"_(4) at 318K has been studied by monitoring the concentration of N_(2)O_(5) in the solution . Initially , concentration of N_(2)O_(5) " is "2.33"mol.L"^(-1) & after 184 minutes , it is reduced to 2.08"mol.L"^(-1) . The reaction takes place according to the equation 2N_(2)O_(5)(g)rarr4NO_(2)(g)+O_(2)(g) . Calculate the average rate of this reaction in terms of hours, minutes & seconds . What is the rate of production of NO_(2) during this period ?
