The correct Answer is:
To solve the question, we will analyze both statements provided and determine their correctness. ### Step 1: Analyze Statement 1 **Statement 1:** Almost all bacteria possess lipoproteinaceous plasma membrane. - **Explanation:** Bacteria, like all living cells, have a plasma membrane. The plasma membrane is primarily composed of lipids and proteins. The term "lipoproteinaceous" indicates that the membrane consists of both lipids and proteins. This is true for almost all bacteria, as they do have a plasma membrane made up of lipids (phospholipids) and proteins. Therefore, this statement is correct. ### Step 2: Analyze Statement 2 **Statement 2:** The plasma membrane of archaebacteria as well as eubacteria have the same type of lipids. - **Explanation:** Archaebacteria and eubacteria (true bacteria) have different types of lipids in their plasma membranes. Archaebacteria typically have a monolayer of branched-chain lipids, while eubacteria have a bilayer of straight-chain fatty acids. This fundamental difference in lipid structure is significant and indicates that this statement is incorrect. ### Conclusion - **Statement 1 is correct.** - **Statement 2 is incorrect.** Thus, the correct option is that Statement 1 is correct, but Statement 2 is incorrect. ### Final Answer The correct option is: **Statement 1 is correct, Statement 2 is incorrect.** ---
