The term 'glycocalyx' is used for:
Correct answer: D. A layer surrounding the cell wall of bacteria.
- A. A layer present between cell wall and membrane of bacteria
- B. Cell wall of bacteria
- C. Bacterial cell glycoengineered to possess N-glycosylated proteins
- D. A layer surrounding the cell wall of bacteria.
Explanation
'Glycocalyx' is a sticky, gelatinous material that collects outside the cell wall of bacteria to form an additional surface layer. When this layer is firmly attached to the surface of the cell, it is called a 'capsule'. If it is loosely distributed around the cell, the glycocalyx is called a 'slime layer'.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
