List I List II (A) Glycocalyx (I) Helps in DNA replication and secretion (B) Cell wall (II) Determines the shape of the cell (C) Plasma membrane (III) Selectively permeable nature (D) Mesosome (IV) May be a loose sheath called slime layer Choose the correct answer from the options given below:
Options
- A(A)-(II), (B)-(IV), (C)-(III), (D)-(I)
- B(A)-(IV), (B)-(II), (C)-(I), (D)-(III)
- C(A)-(IV), (B)-(II), (C)-(III), (D)-(I)
- D(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
Correct answer
C. (A)-(IV), (B)-(II), (C)-(III), (D)-(I)
Step-by-step solution
The prokaryotic cell envelope consists of a tightly bound three-layered structure. (A) Glycocalyx is the outermost layer and differs in thickness and composition among different bacteria. It could be a loose sheath called the slime layer, or thick and tough, called the capsule. Thus, (A) matches with (IV). (B) The cell wall determines the shape of the cell and provides a strong structural support to prevent the bacterium from bursting or collapsing. Thus, (B) matches with (II). (C) The plasma membrane is selectivel
