In which kingdom would you classify the archaea and nitrogen-fixing organism, if the five-kingdom system of classification is used:
- Plantae
- Fungi
- Protista
- Monera
The Correct Option is D
Solution and Explanation
In the five-kingdom system of classification, archaea would be classified under the kingdom Monera. Nitrogen-fixing organisms, which can include certain bacteria, are also typically classified in the kingdom Monera due to their prokaryotic nature.
So, the correct option is (D): Monera

Questions Asked in NEET exam
- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]

Characteristics of Monera Kingdom
The organisms in this kingdom have the following characteristics: -
- Monerans are single-celled creatures.
- The cell wall is made up of peptidoglycan and is stiff.
- Binary fission is asexual reproduction.
- They have 70S ribosomes in them.
- The locomotory organ is the flagella.
- Organelles such as mitochondria, lys
- osomes, plastids, Golgi bodies, endoplasmic reticulum, centrosome, and others are not present.
- These are decomposers and mineralizers for the environment
