Question

Which of the following is not the layer of chemically complex cell envelope of prokaryotic cells?

• A. Glycocalyx
• B. Chromatophore
• C. Cell wall
• D. Cell membrane

Answer 1

Answer: (B)

Chromatophore

Chromatophores are the pigment-containing and light-reflecting cell. They have no contribution to the protection and structure of the cells. Thus, they are not present in the chemically complex cell envelop of prokaryotic organisms.

Glycocalyx surrounds the cell membrane of bacteria. It is a glycoprotein and glycolipid layer.

Cell wall is the outer most layer of the plant cell. It is composed of cellulose.

Cell membrane is made up of lipids and proteins.

So, the correct answer is 'Chromatophore'.
