In Whittaker's five kingdom system of classification, eukaryotes are distributed among

Options

A. two kingdoms
B. three kingdoms
C. four kingdoms
D. all the five kingdoms.

Explanation

To answer the question regarding Whittaker's five kingdom system of classification and the distribution of eukaryotes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Whittaker's Five Kingdom System**:
- Whittaker proposed a classification system that divides living organisms into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.

2. **Identify Eukaryotes**:
- Eukaryotes are organisms whose cells have a nucleus enclosed within membranes. This group includes a wide variety of organisms.

3. **Determine the Kingdoms for Eukaryotes**:
- In Whittaker's classification, the kingdoms that contain eukaryotic organisms are:
- **Protista**: This kingdom includes unicellular and simple multicellular organisms.
- **Plantae**: This kingdom includes all plants, which are multicellular and primarily photosynthetic.
- **Fungi**: This kingdom includes fungi, which are primarily decomposers and can be unicellular (like yeast) or multicellular (like mushrooms).
- **Animalia**: This kingdom includes all animals, which are multicellular and heterotrophic.

4. **Conclusion**:
- Therefore, eukaryotes are distributed among four kingdoms: **Protista, Plantae, Fungi, and Animalia**. The fifth kingdom, **Monera**, consists of prokaryotic organisms.

### Final Answer:
Eukaryotes are distributed among the kingdoms: **Protista, Plantae, Fungi, and Animalia**.
