Question

Turbidity represents a condition when the cell is fully stretched. Why does the cell not burst after attaining turbidity?

Answer 1

In osmosis solvent particles move from lower solute concentration to higher solute concentration until both the solution acquire the same concentration. So when a plant cell is kept in hypertonic solution (having more solute concentration)

Answer 2

t's simply law of osmosis.

In osmosis solvent particles move from lower solute concentration to higher solute concentration until both the solution acquire the same concentration. So when a plant cell is kept in hypertonic solution (having more solute concentration), the solvent particles move outside the cell causing it to shrink, which is also known as plasmolysis of cell.

When a plant cell is kept in hypotonic solution (having less solute concentration), the solvent particles move inside the cell causing it to swell up which is also known as deplasmolysis. But due to the presence of cell wall, plant cell can not burst. Cell wall is a very stratchable boundary made up of cellulose mainly which makes the plant cell non-collapsable (but animal cells can burst in hypotonic solution due to absence of cell wall)

Hope this answers your doubt. :)
