What is the effect of the following on an animal cell:(i) Hypotonic solution (ii) Isotonic solution (iii) Hypertonic solution?

1. When the animal cell is placed in a hypotonic solution (A solution that contains less solute compared to the animal cell), endo-osmosis takes place. The water moves inside the animal cell, thus the cell swells and bursts.

2. When the animal cell is placed in an isotonic solution (Solution having the same concentration of solute as in the cell), no water movement occurs, thus the cell shape will remain unchanged.

3. When the animal cell is placed in a hypertonic solution (A solution having a higher concentration of solute compared to the animal cell), ex-osmosis occurs. The water comes out of the animal cell, the cell shrinks and dies.
