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
- Consider the diameter of a spherical object being measured with the help of a Vernier Callipers. Suppose its 10 Vernier Scale Divisions (V.S.D.) are equal to its 9 Main Scale Divisions (M.S.D.). The least count in the M.S. is 0.1 cm and the zero of V.S. is at -0.1 cm when the jaws of Vernier callipers are closed. If the main scale reading for the diameter is \(M = 5\) cm and the number of coinciding vernier division is 8, the measured diameter after zero error correction, is:

Kingdom Monera
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
