Answer: b) Cell walls prevent cells from dying in hypertonic conditions.
A cell wall is a layer located outside the cell membrane found in plants, fungi and bacteria. The cell wall of bacteria is made up peptidoglycan which gives bacteria a structural support. Peptidoglycan is responsible for the rigidity of the bacterial cell wall and for the determination of it's shape.
A hypertonic solution has a higher concentration of solute and lower concentration of water than the cell. This will cause a net movement of water out of the cell and into the solution by osmosis. Although cell wall is a semipermeable membrane but it will not be able to prevent the water loss. This will result in dehydration of bacterial cell, and cell may die.
Therefore, cell walls does not prevent bacterial cells from dying in hypertonic conditions.
The false statement about bacterial cell walls is the cell wall prevents cells from dying in hypertonic conditions. So, the correct option is B.
What do you mean by Hypertonic solution?
It is a type of solution in which the concentration of solute is higher as compared to the concentration of solvent (water).
The bacterial cell wall is made up of peptidoglycan that provides rigidity to the cell wall. The cell wall is present outside the cell membrane. A hypertonic solution possesses a higher concentration of solute and a lower concentration of water (solvent) in a cell. This results in a movement of water out of the cell through a process of osmosis. Due to semi-permeable in nature, the cell wall still not be able to prevent the amount of water loss from the cell. This leads to a scarcity of water inside the cell leads to dehydration. As a result of this, the cell dies.
Therefore, the false statement about bacterial cell walls is the cell wall prevents cells from dying in hypertonic conditions
