Select incorrect statement regarding plasma membrane in prokaryotes.

Options

A. The plasma membrane interacts with the outside world.
B. It is dissimilar structurally to that of the eukaryotes.
C. Mesosome is formed by the extensions of plasma membrane
D. The plasma membrane is semi-permeable in nature.

Answer

To determine the incorrect statement regarding the plasma membrane in prokaryotes, we can analyze the provided information step by step:

### Step 1: Understanding the Structure of the Plasma Membrane
The plasma membrane in prokaryotes is a fundamental structure that separates the interior of the cell from the external environment. It is described as semi-permeable, which means it allows certain substances to pass through while restricting others.

**Hint:** Recall the definition of a semi-permeable membrane and its function in cellular processes.

### Step 2: Identifying the Components of the Plasma Membrane
The plasma membrane of prokaryotes is composed of phospholipids and proteins. This composition is similar to that of eukaryotic cells, which also have a plasma membrane made up of lipids and proteins.

**Hint:** Compare the composition of prokaryotic and eukaryotic membranes to see if they share similarities.

### Step 3: Evaluating the Statement about Mesosomes
Mesosomes are structures formed by the invagination of the plasma membrane in prokaryotes. They can take various forms, such as lamellae or vesicles, and are indeed extensions of the plasma membrane.

**Hint:** Consider the function and formation of mesosomes in prokaryotic cells.

### Step 4: Analyzing the Incorrect Statement
The statement in question claims that the plasma membrane of prokaryotes is dissimilarly structured to that of eukaryotes. This is incorrect because, as established, both prokaryotic and eukaryotic plasma membranes share a similar structure composed of lipids and proteins.

**Hint:** Look for statements that contradict the known similarities in membrane structure between prokaryotes and eukaryotes.

### Conclusion
The incorrect statement regarding the plasma membrane in prokaryotes is that it is dissimilarly structured to that of eukaryotes. In reality, they share a similar structural composition.

**Final Answer:** The incorrect statement is: "The plasma membrane is dissimilarly structured to that of eukaryotes."
