FAQs on Kingdom Monera: Archaebacteria & Eubacteria Video Lecture - Biology Class 11 - NEET

1. What are Archaebacteria and Eubacteria?
Ans. Archaebacteria and Eubacteria both belong to the Kingdom Monera. Archaebacteria are considered "ancient bacteria" and are known for their ability to survive in extreme environments, such as hot springs and deep-sea vents. Eubacteria are commonly found in soil, water, and the human body, and are known for their diverse metabolic capabilities.
2. What are some examples of Archaebacteria and Eubacteria?
Ans. Some examples of Archaebacteria include methanogens, halophiles, and thermoacidophiles. Methanogens are found in anaerobic environments, such as swamps and the digestive tracts of animals, and produce methane gas. Halophiles are found in extremely salty environments, such as the Dead Sea. Thermoacidophiles are found in hot, acidic environments, such as hot springs. Eubacteria include a wide variety of bacteria, such as Escherichia coli, Streptococcus, and Staphylococcus.
3. What is the difference between Archaebacteria and Eubacteria?
Ans. The main difference between Archaebacteria and Eubacteria lies in their genetic makeup and cell wall composition. Archaebacteria have a different type of cell wall than Eubacteria, and their DNA replication and transcription processes are more similar to those of eukaryotes than to other bacteria. Additionally, Archaebacteria are known for their ability to survive in extreme environments, while Eubacteria are more commonly found in everyday environments.
4. How do Archaebacteria and Eubacteria benefit humans?
Ans. Archaebacteria and Eubacteria both have important roles in human health and industry. Eubacteria are used in the production of food, such as cheese and yogurt, and in the production of antibiotics and other pharmaceuticals. Archaebacteria are used in the production of enzymes that are used in industrial processes, such as paper production and wastewater treatment. Additionally, some Archaebacteria have potential medical applications, such as in the treatment of cancer.
5. How do Archaebacteria and Eubacteria impact the environment?
Ans. Archaebacteria and Eubacteria play important roles in the environment. Eubacteria are involved in the nitrogen cycle, which is important for plant growth, and some Eubacteria are able to break down pollutants in the environment. Archaebacteria also play roles in biogeochemical cycles, such as the sulfur cycle, and some Archaebacteria are able to produce methane gas, which is an important greenhouse gas. However, some bacteria can also be harmful to the environment, such as those that cause diseases in plants and animals.
