Question

Explain what happens to animal cells placed in isotonic, hypotonic and hypertonic solutions. Which is best suited for most animal cells?

Answer 1

• HYPOTONIC SOLUTION

When the external solution is more dilute, or we can say hypotonic, in such case water will move into the cell until amd unless it balances the internal and external concentration. As a result of which the cell enlarge. Such changes can be minor or, if the change is severe, it can damage or destroy the cell.

• Isotonic Solutions

In an Isotonic solution there is no concentration gradient. Hence,there would be no net flow of water between the cells and the solution. Here the rate of exiting and entering the cell are equal. There is no net change in the cell's appearance.

• HYPERTONIC SOLUTION

In hypertonic environments, water rushes out of the cell, which causes the cell to shrink which results the cells to be dehydrated and lose most or all physiological functions while in the shrivelled state.

Best Suited is Isotonic Solution
