Which of the following statements regarding the bacterial cell envelope and its modifications is incorrect?
A. Most prokaryotic cells, particularly bacterial cells, have a chemically complex cell envelope.
B. The cell envelope consists of a tightly bound three-layered structure: glycocalyx, cell wall, and plasma membrane.
C. Extensions of the plasma membrane into the cell in the form of vesicles, tubules, and lamellae are called inclusion bodies.
D. Fimbriae are small bristle-like fibers sprouting out of the cell that help in attaching bacteria to rocks or host tissues.
E. The plasma membrane of prokaryotes is structurally different from that of eukaryotes.
Choose the correct answer from the options given below:
A, B, D only
C and E only
B, C, E only
A and D only
C (Incorrect): These extensions are called mesosomes, not inclusion bodies. Inclusion bodies are for storage and are not membranous extensions.
E (Incorrect): The plasma membrane of prokaryotes is structurally similar to that of eukaryotes (both are phospholipid bilayers).
A, B, D (Correct): These are standard NCERT facts about the bacterial cell envelope and surface structures.
