Class 11 Biology Ch-11 page no. 180 figure 11.3 answer.
a) Solution of which chamber has a lower water potential?
b) Solution of which chamber has a lower solute potential?
c) In which direction will osmosis occur?
d) Which solution has a higher solute potential?
e) At equilibrium which chamber will have lower water potential?
f) If one chamber has a of -2000kPa. and the other -1000kPa which is the chamber that has the higher ?
Answers are - (a) solution B because it has more solute content. (b) solution B because chamber B has more osmotic pressure and as solute potential is negative of osmotic pressure hence chamber B has a lower solute potential! (c) as solvent moves from a region of greater water potential to a region of lower water potential hence osmosis occurs from A to B (d) A has higher solute potential again the resion for it is mentioned in sol (b) (e) at equilibrium there will be no net flow of solvent molecule as the osmotic potential becomes same in both the chambers , hence both the chambers will have equal water potential (f) maximum water potential is 0(zero) hence -1000 is bigger than -2000 so, solution with water potential of -1000 has higher water potential
