Questions And Correct Answers.
For prokaryotic cells, which statement is correct concerning how the structure of a particular cell
component correlates with its function?
- The cell wall represents infoldings of the plasma membrane that protect the cell and give it shape and
rigidity.
- The cell wall is a tough, fibrous layer that protects the cell and gives it shape and rigidity.
- Photosynthetic membranes contain magnetite that allows the cell to convert magnetic field energy into
chemical energy.
- Photosynthetic membranes are composed of crosslinked polymers like peptidoglycan that provide
extensive surface area for photosynthesis. - Answer The cell wall is a tough, fibrous layer that protects
the cell and gives it shape and rigidity.
