Plants having flowers with free petals are placed under

Options

A. Polypetalae
B. Gamopetalae
C. Monocotyledons
D. Monochlamydae

Answer

To answer the question "Plants having flowers with free petals are placed under," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Flower Structure**:
- Flowers can have petals that are either free (not fused) or fused together. This is an important distinction in plant morphology.

2. **Identifying Terms**:
- **Polypetalous**: This term refers to flowers with free petals. In these flowers, each petal is separate from the others.
- **Gamopetalous**: This term refers to flowers with fused petals, where the petals are joined together.
- **Monocotyledon**: This refers to plants that have one cotyledon (seed leaf) and does not specifically relate to petal structure.
- **Dicotyledon**: This refers to plants with two cotyledons and also does not relate to petal structure.
- **Monochlamydeous**: This refers to flowers that lack petals altogether, having only sepals.

3. **Analyzing the Options**:
- The first option, **Polypetalous**, is the correct choice as it describes flowers with free petals.
- The second option, **Gamopetalous**, is incorrect because it describes flowers with fused petals.
- The third option, **Monocotyledon**, is not relevant to the question about petals.
- The fourth option, **Monochlamydeous**, is also incorrect as it indicates the absence of petals.

4. **Conclusion**:
- Based on the definitions and analysis, the correct answer is **Polypetalous**, as it specifically refers to plants that have flowers with free petals.

### Final Answer:
Plants having flowers with free petals are placed under **Polypetalous**.
