Question

For prokaryotic cells, which statement is correct concerning how the structure of a particular cell component correlates withits function?

a. The cell wall is a tough, fibrous layer that protects the cell and gives it shape and rigidity.
b. The cell wall represents infoldings of the plasma membrane that protect the cell and give it shape and rigidity.
c. Photosynthetic membranes contain magnetite that allows the cell to convert magnetic field energy into chemicalenergy.
d. Photosynthetic membranes are composed of crosslinked polymers like peptidoglycan that provide extensivesurface area for photosynthesis.

Answer 1

Answer:

a. The cell wall is a tough, fibrous layer that protects the cell and gives it shape and rigidity.

Explanation:

Bacteria and archaea comes under prokaryotes and they both have cell wall outside their cell membrane. The cell wall in bacteria is made up of peptidoglycan and in archaea, it is made up of pseudo-peptidoglycan.  

The cell wall in prokaryotes are tough structures that protect the cell from any damage. The cell wall is responsible for providing shape and rigidity to prokaryotic cell because the cell wall acts as a framework for cell and prevent the exploding and over expansion of cell.  

Cell wall in prokaryotes surrounds the cytoplasmic membrane of prokaryotes and prevent osmotic lysis of cell. So the right answer is a.
