Question

Parth conducted an experiment with two de-
shelled eggs. He kept one egg in a hypotonic salt
solution and another in a hypertonic salt solution.
Which of the following statements are correct
about his observation?
1. The egg in hypotonic salt solution will swell.
II. The egg in hypertonic salt solution will swell
The egg in hypotonic salt solution will shrink.
IV. The egg in hypertonic salt solution will
shrink.​

Answer 1

Answer:2nd and 3rd

Explanation:Water is known as hypotonic, ie. very dilute and contains more water than the egg. ... There is a much higher water concentration in the egg than in the syrup so water will pass in the opposite direction. This means that the egg will shrink in size.

Answer 2

If one egg in a hypotonic salt solution and another in a hypertonic salt solution then observations I and IV are correct.

• The egg membrane is an example of a semi-permeable membrane and osmosis can occur through it.
• When an egg is placed in a hypotonic solution, the surrounding medium has a higher water concentration gradient. Water will thus enter into the egg causing it to swell.
• When an egg is placed in a hypertonic solution, the amount of water is higher in the egg than in the surrounding, so water will flow into the opposite direction. So, the egg will shrink.
