FAQs on Overview: Kingdom Monera Video Lecture - Biology Class 11 - NEET
| 1. What is Kingdom Monera? |  |
Ans. Kingdom Monera is a taxonomic group that includes all unicellular prokaryotic organisms. They are classified based on their cellular structure, mode of nutrition, and reproduction. Bacteria and cyanobacteria are the two main groups of Kingdom Monera.
| 2. What are the characteristics of Kingdom Monera? | |
Ans. The characteristics of Kingdom Monera include unicellular structure, prokaryotic cells, absence of membrane-bound organelles, reproduction through binary fission, and diverse modes of nutrition. They can be autotrophic, heterotrophic, or chemotrophic.
| 3. What are the different types of bacteria under Kingdom Monera? | |
Ans. The different types of bacteria under Kingdom Monera include Gram-positive bacteria, Gram-negative bacteria, cyanobacteria, spirochetes, chlamydia, and Rickettsia. Gram-positive bacteria have a thick peptidoglycan layer in their cell walls, while Gram-negative bacteria have a thin peptidoglycan layer and an outer membrane.
| 4. How does Kingdom Monera impact the environment? | |
Ans. Kingdom Monera plays a significant role in the environment. Bacteria are involved in the process of decomposition and nutrient cycling, and some bacteria can fix atmospheric nitrogen, converting it into a form that plants can use. Cyanobacteria, also known as blue-green algae, are photosynthetic bacteria that play a crucial role in aquatic ecosystems.
| 5. How are antibiotics used to control bacterial infections? | |
Ans. Antibiotics are medications that are used to control bacterial infections. They work by either killing the bacteria or stopping their growth. Antibiotics target specific components of the bacterial cell, such as cell wall synthesis, protein synthesis, or DNA replication. However, the misuse of antibiotics can lead to antibiotic resistance, making it difficult to treat bacterial infections.
