Three Major Domains of life was proposed by carl Woese which includes

Options

A. Eubacteria, Archaea and Eucarya
B. Monera, Plantea and Animalia
C. Bacteria,Plantea, Eukarya
D. Cynobacteria, Plantea,Animalia

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the three major domains of life proposed by Carl Woese.

2. **Identifying the Domains**: Carl Woese proposed a classification system that divides all living organisms into three domains:
- **Eubacteria** (also known as Bacteria)
- **Archaea**
- **Eukarya**

3. **Explaining Each Domain**:
- **Eubacteria**: This domain includes all true bacteria, characterized by their prokaryotic cell structure, which means they lack a nucleus.
- **Archaea**: Similar to Eubacteria in being prokaryotic, but they have distinct biochemical and genetic properties. They often inhabit extreme environments and include organisms such as methanogens, halophiles, and thermophiles.
- **Eukarya**: This domain includes all eukaryotic organisms, which have a nucleus and include kingdoms such as fungi, plants, and animals.

4. **Reviewing the Options**: The options provided in the question are:
- A) Eubacteria, Archaea, and Eukarya
- B) Monera, Plantae, and Animalia
- C) Bacteria, Plantae, and Eukarya
- D) Cyanobacteria, Plantae, and Animalia

5. **Analyzing the Options**:
- Option A correctly lists the three domains proposed by Woese.
- Options B, C, and D do not accurately reflect Woese's classification and include outdated or incorrect terms.

6. **Conclusion**: The correct answer to the question is **A) Eubacteria, Archaea, and Eukarya**.
