In Whittaker's five kingdom classification, eukaryotes were assigned to

Options

A. all the five kingdoms
B. two of the five kingdoms
C. four of the five kingdoms
D. Only one of the five kingdoms

Answer

**Step-by-Step Solution:**

1. **Understanding Whittaker's Classification**: R.H. Whittaker proposed a five-kingdom classification system in 1969. This system categorizes living organisms into five distinct kingdoms based on certain characteristics.

2. **Identifying the Kingdoms**: The five kingdoms in Whittaker's classification are:
- Kingdom Monera: Comprises unicellular prokaryotic organisms (e.g., bacteria).
- Kingdom Protista: Comprises mostly unicellular eukaryotic organisms (e.g., protozoa, algae).
- Kingdom Fungi: Comprises multicellular and unicellular eukaryotic organisms (e.g., molds, yeasts).
- Kingdom Plantae: Comprises multicellular eukaryotic organisms that are primarily photosynthetic (e.g., plants).
- Kingdom Animalia: Comprises multicellular eukaryotic organisms that are heterotrophic (e.g., animals).

3. **Determining Eukaryotic Kingdoms**: In Whittaker's classification, the kingdoms that contain eukaryotic organisms are:
- Protista
- Fungi
- Plantae
- Animalia

4. **Conclusion**: Therefore, eukaryotes were assigned to four of the five kingdoms in Whittaker's classification. The correct answer to the question is that eukaryotes were assigned to **4 of the 5 kingdoms**.

**Final Answer**: Eukaryotes were assigned to 4 of the 5 kingdoms in Whittaker's classification.
