Quizplus · Accepted Answer

The correct order starting from the interior of some prokaryotes is the cell membrane, followed by the peptidoglycan cell wall (characteristic of bacteria), then a polysaccharide-rich phospholipid membrane if present (as in Gram-negative bacteria), and finally, an outer capsule if one exists. This structure is typical for bacteria that have complex cell envelopes, including both Gram-positive and Gram-negative bacteria, though the outer polysaccharide-rich phospholipid membrane is specific to Gram-negative bacteria.
