The correct answer is option 'D' - Monera. Let's understand why Monera is the correct kingdom for blue-green algae, nitrogen-fixing bacteria, and methanogenic archaebacteria in the 5-kingdom classification system.
The Five Kingdom Classification System:
The Five Kingdom Classification System was proposed by Robert Whittaker in 1969. It categorizes all living organisms into five major groups or kingdoms based on their characteristics and evolutionary relationships. The five kingdoms are:
1. Kingdom Animalia: includes all multicellular animals.
2. Kingdom Plantae: includes all multicellular plants.
3. Kingdom Fungi: includes all multicellular fungi and some unicellular organisms.
4. Kingdom Protista: includes all unicellular eukaryotes.
5. Kingdom Monera: includes all prokaryotes (unicellular organisms lacking a nucleus).
Explanation:
Now, let's look at the given organisms - blue-green algae, nitrogen-fixing bacteria, and methanogenic archaebacteria - and determine which kingdom they belong to.
1. Blue-green algae (Cyanobacteria): Blue-green algae are photosynthetic bacteria that can produce their food through photosynthesis. They are prokaryotic organisms and lack a true nucleus. They belong to the kingdom Monera.
2. Nitrogen-fixing bacteria: Nitrogen-fixing bacteria are a group of bacteria that can convert atmospheric nitrogen into a usable form for plants. They are also prokaryotic organisms and belong to the kingdom Monera.
3. Methanogenic archaebacteria: Methanogenic archaebacteria, also known as methanogens, are a group of microorganisms that produce methane gas as a byproduct of their metabolism. They are also prokaryotes and belong to the kingdom Monera.
Conclusion:
Based on the characteristics of these organisms, it is evident that they all belong to the kingdom Monera. This kingdom includes prokaryotic organisms such as bacteria and archaea. Blue-green algae, nitrogen-fixing bacteria, and methanogenic archaebacteria are all examples of prokaryotic organisms, and hence, they fall under the kingdom Monera in the 5-kingdom classification system.
