According to which phylogenetic system , dicots are advance with sympetalae conditions ?

Options

A. Bentham & Hooker's
B. Engler & Prantl
C. Hutchinson
D. Takhtajan

Answer

To answer the question, "According to which phylogenetic system are dicots considered advanced with sympetalae conditions?", we can follow these steps:

### Step 1: Understand the Terms
- **Dicots**: These are plants that have two cotyledons (seed leaves) in their seeds.
- **Sympetalae**: This refers to a condition where the petals of flowers are fused together.

### Step 2: Review Phylogenetic Systems
- There are various phylogenetic classification systems proposed by different scientists, including:
1. Bentham and Hooker
2. Engler and Prantl
3. Hutchinson
4. Takhtajan

### Step 3: Analyze Bentham and Hooker's Classification
- Bentham and Hooker proposed a classification system that categorized seed plants into three classes:
- Dicotyledony (dicots)
- Gymnospermae (gymnosperms)
- Monocotyledony (monocots)
- They suggested that dicots were more advanced due to the presence of sympetalae conditions.

### Step 4: Compare with Other Classifications
- Hutchinson later revised the understanding of phylogeny, suggesting that gymnosperms evolved first, followed by monocots, and then dicots.
- However, Hutchinson did not specifically categorize dicots as advanced with sympetalae conditions.

### Step 5: Conclusion
- Based on the information, the classification system that considers dicots as advanced with sympetalae conditions is **Bentham and Hooker's classification**.

### Final Answer
The answer to the question is **Bentham and Hooker's classification**.
