Archaebacteria differ from other bacteria in having different……..

Options

A. Size
B. Shape
C. Cell wall
D. Ribosome

Answer

**Step-by-step Solution:**

1. **Understanding the Classification of Bacteria:**
- Bacteria are classified into two main groups: Archaebacteria and Eubacteria. Both groups fall under the Monera kingdom, which consists of prokaryotic organisms.

2. **Identifying the Unique Features of Archaebacteria:**
- Archaebacteria are known for their ability to thrive in extreme environments, such as highly saline, acidic, or hot conditions. This adaptability is a key characteristic that sets them apart from Eubacteria.

3. **Examining the Differences in Cell Wall Structure:**
- One of the primary differences between Archaebacteria and other bacteria lies in the structure of their cell walls.
- Archaebacteria have a unique cell wall composition that includes glycerol ester lipids, glycolipids, amino acids, and glycoproteins.
- In contrast, Eubacteria typically have cell walls made of peptidoglycan, which is absent in Archaebacteria.

4. **Conclusion:**
- The distinct cell wall structure of Archaebacteria is crucial for their survival in extreme conditions. Therefore, the statement that "Archaebacteria differ from other bacteria in having different cell wall structure" is accurate.

**Final Answer:**
Archaebacteria differ from other bacteria in having different cell wall structure.
