Understanding Bacteria and Their Characteristics
Bacteria are fascinating microorganisms that play diverse roles in ecosystems and human health. Among the statements provided, option 'C' is correct. Here's an explanation of why this is true and why the other statements are false.
True Statement: Bacteria Can Reproduce Through Binary Fission
- Bacteria primarily reproduce asexually through a process called binary fission.
- In binary fission, a single bacterial cell divides into two identical daughter cells.
- This method allows for rapid population growth under favorable conditions.
False Statements: Analyzing the Other Options
- a) Bacteria are eukaryotic organisms.
- Bacteria are prokaryotic organisms, meaning they lack a nucleus and other membrane-bound organelles.
- This distinguishes them from eukaryotes, which include plants, animals, and fungi.
- b) Bacteria lack a cell membrane.
- Bacteria do possess a cell membrane, which is essential for maintaining the integrity of the cell and regulating what enters and exits.
- The cell membrane is crucial for their survival and function.
- d) Bacteria are always harmful to humans.
- While some bacteria can cause diseases, many are beneficial and essential for human health.
- For instance, gut bacteria aid in digestion and play a role in the immune system.
Conclusion
In summary, option 'C' is correct because bacteria can reproduce through binary fission, a fundamental characteristic of these organisms. The other statements are inaccurate, highlighting the complexity and diversity of bacteria in nature. Understanding bacteria's roles can help us appreciate their importance, both harmful and beneficial.
