A cell wall is a requirement for all living bacteria. Is this statement True or False? True False

**False** Not all living bacteria have a cell wall. While the majority of bacteria possess a cell wall that provides structure and protection, there are notable exceptions. For example, **Mycoplasma** species lack a cell wall entirely. These bacteria maintain their shape and structural integrity through other means, such as a flexible cell membrane. The absence of a cell wall in such bacteria makes them naturally resistant to antibiotics like penicillin, which target cell wall synthesis. **Key Points:** - **Most Bacteria:** Have a cell wall composed of peptidoglycan. - **Exceptions:** Some bacteria, such as *Mycoplasma*, do not have a cell wall. - **Implications:** Lack of a cell wall affects bacterial shape, growth, and antibiotic susceptibility. Therefore, the statement "A cell wall is a requirement for all living bacteria" is **False**.
