Answer 2

The percentage of water absorbed = mass of water absorbed/ mass of raisin x100 = 5/20x100 = 25%

Explanation:

• This is due to osmosis. Osmosis is the movement of the solvent particle from the region of comparatively lower concentration to the region of comparatively higher concentration across a semipermeable membraneOsmosis is the movement of the solvent particle from the region of comparatively lower concentration to the region of comparatively higher concentration across a semipermeable membrane

• The balance in the cell is maintained by the process of osmosis.

• when the amount of solute inside the cell increases the cell becomes hypertonic. Then Water enters into the cell to maintain the osmolarity.

• Similarly when the amount of solute which is present inside the cell is less than that of the environment than water moves out from the body of the cell to the outside. In this process the molarity of the cell is maintained.
