Which of the following conclusions about a flower can't be deduced just by observing the floral formula ?

Options

A. The flower has epipetalous stamens .
B. The flowers has epigenous insertion of floral whorls .
C. The flower has epigenous insertion of floral whorls.
D. The flower is actinomorphic.

Answer

To solve the question about which conclusion about a flower can't be deduced just by observing the floral formula, we will analyze each option based on the information provided in the video transcript.

### Step-by-Step Solution:

1. **Understanding Floral Formula**: The floral formula is a shorthand representation of the structure of a flower, indicating the number and arrangement of its parts (sepals, petals, stamens, and carpels).

2. **Analyzing Option A**:
- **Statement**: The flower has epipetalous stamens (stamens attached to petals).
- **Floral Formula Representation**: This can be indicated in the floral formula, typically represented as "SS" (stamens attached to petals).
- **Conclusion**: This can be deduced from the floral formula.

3. **Analyzing Option B**:
- **Statement**: The flower has epigenous insertion of the floral organs (ovary located below other floral parts).
- **Floral Formula Representation**: This is not explicitly shown in the floral formula.
- **Conclusion**: This cannot be deduced just by observing the floral formula.

4. **Analyzing Option C**:
- **Statement**: The flower has epigenous insertion of floral organs (this option is the same as option B).
- **Conclusion**: Similar to option B, this cannot be deduced just by observing the floral formula.

5. **Analyzing Option D**:
- **Statement**: The flower is echinomorphic (having radial symmetry).
- **Floral Formula Representation**: Echinomorphic flowers can be represented in the floral formula, indicating their symmetry.
- **Conclusion**: This can be deduced from the floral formula.

### Final Conclusion:
Based on the analysis, the option that cannot be deduced just by observing the floral formula is **Option B** (the flower has epigenous insertion of the floral organs).
