Question

Tara placed a grape in a solution, after sometime she noticed that the grape started to shrink.

a. Name the solution and explain.
b. Then Tara placed the raisin in a solution and noticed it started to swell up. Name the solution and explain

Answer 1

a. Hypertonic solution

b. Hypotonic solution

Step-by-step explanation:

There are basically 3 types of solutions in biology,

1) Isotonic-Same concentration of solute and solvent inside the grape and in the solution.

2)Hypotonic solution-More concentration of solvent in the solution than in the grape.

3)Hypertonic solution-More concentration of solvent in the grape than in the solution.

Now,

a. Tara had kept the grape in a hypertonic solution. The solvent will start draining from the grape to equalize the concentrations of solvent inside and outside. So, the grape shrank due to loss of water.

b. Tara kept it in a hypotonic solution. The solvent will start entering the grape to equalize the concentrations of solvent. So, the grape started swelling.
