NEET · Biology · STD 11 - 8. Cell the unit of life

The term "glycocalyx" is used for

A a layer present between cell wall and membrane of bacteria
B cell wall of bacteria
C bacterial cell glyco engineered to possess N-glycosylated proteins
D a layer surrounding the cell wall of bacteria.

Verified Solution

Answer & Solution

Correct Answer

(D) a layer surrounding the cell wall of bacteria.

Step-by-step Solution

Detailed explanation

(d) : 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.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
