Question

A de-shelled egg, when placed in glucose solution swells up. What can you
say about the concentration of the glucose solution relative to that of the
egg? Differentiate between different types of solutions on the basis of
their concentration.

Answer 1

Explanation:

The cell will shrink due to exosmosis. Deshelled eggs are prepared by placing the egg in dilute HCL acid for 10 hours. Now the egg is covered with only semipermeable membrane. When this is placed in a salt solution (hypertonic solution), exosmosis occurs and the egg shrinks due to loss of water to the surrounding.

Answer 2

Answer:

The concentration of in the glucose solution is higher than the concentration inside the cells of the egg. This means that glucose is a hypotonic solution.

There are three types of solutions on the basis of its concentration.

1. Hypotonic solution

Concentration of water inside the cell is less than concentration of water outside the cell.

Result in net water gain.( In a cell)

Cell swells.

2. Hypertonic solution

Concentration of water inside the cell is more than concentration of water outside the cell.

Results in net water loss.(in a cell)

Cell shrinks

3. Isotonic solution

Concentration of water inside the cell is equal to the concentration of water outside the cell.

There is neither loss or gain of water.

Cell size remains same.
