The Non- nucleated unicellular organisms of whittaker's (1969) Classification are included in the kingdom

Options

A. Plantae
B. Monera
C. Protista
D. Animalia.

Answer

**Step-by-Step Solution:**

1. **Understanding Whitaker's Classification**: In 1969, Robert Whittaker proposed a five-kingdom classification system. The five kingdoms are Monera, Protista, Fungi, Plantae, and Animalia.

2. **Identifying Non-Nucleated Organisms**: The question specifically asks about non-nucleated unicellular organisms. Non-nucleated organisms are those that lack a true nucleus.

3. **Classifying Prokaryotes**: In Whittaker's classification, the kingdom Monera is where all prokaryotic organisms are placed. Prokaryotes are characterized by the absence of a true nucleus and membrane-bound organelles.

4. **Characteristics of Monera**: The organisms in the kingdom Monera include bacteria, cyanobacteria, and archaebacteria. All these organisms are unicellular and do not possess a true nucleus, making them non-nucleated.

5. **Excluding Other Kingdoms**: The other kingdoms mentioned (Plantae, Protista, and Animalia) consist of eukaryotic organisms, which have a true nucleus and membrane-bound organelles. Therefore, they cannot be classified as non-nucleated.

6. **Conclusion**: Based on the classification and characteristics discussed, the correct answer to the question is that the non-nucleated unicellular organisms are included in the kingdom Monera.

**Final Answer**: The non-nucleated unicellular organisms of Whittaker's (1969) classification are included in the kingdom Monera.
