Question

The bacterial envelope consists of three layered structure.
Which layers(s) is/are structurally similar to that of the
eukaryotes?

Answer 1

Answer:

Primary layer secondary layer

Answer 2

Most of the prokaryotic cells(bacteria) have a chemically complex cell envelope.

Explanation:

The bacterial envelope is a tightly bounded three-layer structure. Following are the 3 layers

1. Glycocalyx: It is the outermost layer comprising a coating of mucous or polysaccharide macromolecules. It differs according to bacteria. Some have loose sheath called a slime layer while others have a thick and tough covering called the capsule. This is absent in eukaryotes.
2. Cell wall: Both eukaryotes and bacterial cell have a cell wall but they differ in chemical composition. The bacterial cell wall is rigid due to the presence of peptidoglycan.
3. Plasma membrane: It is semi-permeable. It is structurally similar to that of eukaryotes.

So, the answer is the plasma membrane.
