Question

Starting from interior to exterior, arrange the following in correct order:
A. Periplasmic space
B. Nucleus
C. Plasma membrane
D. Cell wall
E. Endoplasmic reticulum
Choose the correct answer from the options given below:

• A. B, E, A, C, D
• B. B, E, C, D, A
• C. B, E, C, A, D
• D. B, A, E, C, D

Hint:

Cell organization from inside out:
Nucleus $\rightarrow$ Endoplasmic reticulum $\rightarrow$ Plasma membrane $\rightarrow$ Periplasmic space $\rightarrow$ Cell wall.
This sequence applies to plant cells and bacteria.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
This question tests the structural organization of a typical cell from the interior to the exterior.

Step 2: Detailed Explanation:
The correct order from interior to exterior is:
1. Nucleus (B): The innermost part of the cell (in eukaryotic cells).
2. Endoplasmic reticulum (E): Surrounds the nucleus and extends through the cytoplasm.
3. Plasma membrane (C): The lipid bilayer that encloses the cell.
4. Periplasmic space (A): A region between the plasma membrane and the cell wall (found in Gram-negative bacteria).
5. Cell wall (D): The outermost layer (in plant cells and bacteria).
Thus, the correct sequence is B, E, C, A, D.

Step 3: Final Answer:
Thus, the correct order from interior to exterior is B, E, C, A, D, which corresponds to option (C).
