Answer:
C. serve as a rigid barrier to prevent cell lysis
Explanation:
The cell wall of bacteria is mainly made up of peptidoglycan and of plant is made up of cellulose. It is present outside the cell membrane. The cell wall is a rigid layer that provides structural and mechanical support to the cell and helps in defining the shape of the cell.
It protects the cell from mechanical stress and prevents the cell from osmotic lysis or cell bursting. The cell wall of bacteria is common to target for many antibiotics because the animal cell does not contain a cell walls. Therefore the correct answer is C.
