Question

Egg membranes from three eggs were carefully taken out and labeled as A, B and C. Each of these membranes were filled with 1% solution of sugar. Membrane A was immersed in 0.5% sugar solution, Membrane B was immersed in 1% sugar solution and Membrane C was immersed in 2% sugar solution. Predict the behaviour of the three membranes.

Answer 1

This problem is related to the tonicity of the solutions. If there is more solute outside the egg than inside, the egg is in a hypertonic solution. Water will leave the egg causing the egg to shrink. If there is more solute inside the egg than inside, it is in a hypotonic solution. Water will enter the egg causing it to swell. If the solute concentration is equal on both sides, it's in an isotonic solution. There is no net movement of water so the egg will mostly remain the same. 

Answer 2

Answer:

For membrane A: Water will flow inside the cell.

Membrane A is in a Hypotonic soluion.

For membrane B: There will be no movement of water.

Membrane B is in an Isotonic solution.

For membrane C: Water will flow out of the cell.

Membrane C is in a Hypertonic solution.
