Select the incorrect statement with respect to the plasma membrane.
(a) It is selective permeable.
(b) It is elastic in nature.
(c) It is not living
(d) It is quasi fluid nature.

Options

A. It is selective permeable.
B. It is elastic in nature.
C. It is not living
D. It is quasi fluid nature.

Answer

To solve the question, we need to evaluate each statement regarding the plasma membrane and identify which one is incorrect.

**Step 1: Analyze each statement.**

(a) **It is selectively permeable.**
- The plasma membrane is indeed selectively permeable, meaning it allows certain substances to pass while restricting others. This is a fundamental characteristic of the plasma membrane.

(b) **It is elastic in nature.**
- The plasma membrane has elastic properties, allowing it to change shape and accommodate various cellular processes. This statement is also true.

(c) **It is not living.**
- The plasma membrane is a crucial component of living cells. While it is not a living entity on its own, it is part of living cells and plays an essential role in their functions. This statement is misleading and can be considered incorrect.

(d) **It is quasi fluid in nature.**
- The plasma membrane exhibits a quasi-fluid nature, which means it has fluid-like properties but is not completely fluid. This characteristic is well-established in the fluid mosaic model of the membrane. This statement is true.

**Step 2: Identify the incorrect statement.**
After analyzing all the statements, we find that option (c) "It is not living" is the incorrect statement regarding the plasma membrane.

**Final Answer: (c) It is not living.**
