Question

13. A plant cell with a water potential of - 700 kPa is imunersed in a sucrose solution whose water potential
S-350. In which direction-water moves and what is nos xovement of water:
From sucrose solution, - 175 kPa b. From cell. - 175 kPa
From surose solution, - 350 kPa
d. From cell, - 350 kPa

Answer 1

Answer:

ANSWER

Osmotic potential is the decrease in chemical potential of pure water due to the presence of solute particle in it. Osmotic potential is directly proportional to the solute concentration. The water potential is addition of osmotic potential and pressure potential. Pressure potential or turgor pressure of the flaccid cell is zero. Osmotic pressure is the pressure exerted by the solutes.

It is given that 0.5 M Sucrose solution develops a pressure of 15 bars in an osmometer. Hence, the osmotic pressure of the given solution is -15 bars. Its pressure potential is 0 bars. Its water potential is -15 bars. Its Osmotic pressure is +15 bars.

Thus, the correct answer is 'That its pressure potential is −15 bars.'
