why is the cell wall a rigid structure
Answers
Answer:
In most cells, the cell wall is flexible, meaning that it will bend rather than holding a fixed shape, but has considerable tensile strength. The apparent rigidity of primary plant tissues is enabled by cell walls, but is not due to the walls' stiffness. Hydraulic turgor pressure creates this rigidity, along with the wall structure.
Explanation:
Answer:
Peptidoglycan is a polymer composed of double-sugars and amino acids (protein subunits). This molecule gives the cell wall rigidity and helps to give bacteria shape. Peptidoglycan molecules form sheets which enclose and protect the bacterial plasma membrane.
Plant do not have any exoskeleton or endoskeleton like animals, therefore for strength, structure shape and support plants need cell walls made of cellulose. For all these functions cell wall has a rigid structure.
