Which of the following describes the characters of the family Fabaceae?

Options

A. pinnately compound leaf, zygomorphic flower, racemose
B. reticulate venation, zygomorphic, cymose
C. estipulate, actinomorphic, synandrous
D. alternate leaves, bisexual, bicarpellary

Answer

To determine the characters of the family Fabaceae, we need to analyze the given options and identify which one accurately describes the characteristics of this plant family.

### Step-by-Step Solution:

1. **Understanding the Family Fabaceae**:
- Fabaceae, also known as the legume, pea, or bean family, is characterized by specific morphological features.

2. **Analyzing Option 1**:
- **Pinnately Compound Leaf**:
- This type of leaf is characterized by leaflets arranged on either side of a central stalk (rachis). This is a common feature in many members of the Fabaceae family.
- **Zygomorphic Flower**:
- Zygomorphic flowers can be divided into two equal halves along one plane. This is also a typical characteristic of many Fabaceae flowers.
- **Racemose Inflorescence**:
- Racemose inflorescence refers to a type of flower arrangement where the main axis continues to grow and flowers are borne laterally. This is seen in many plants of the Fabaceae family.
- **Conclusion for Option 1**: All three features (pinnately compound leaves, zygomorphic flowers, and racemose inflorescence) are characteristic of the Fabaceae family.

3. **Analyzing Option 2**:
- **Reticulate Venation**:
- While some plants in Fabaceae may exhibit reticulate venation, it is not a defining characteristic of the entire family.
- **Zygomorphic**:
- This is correct, but the other features do not align with Fabaceae.
- **Enzyme Moss**:
- This term is not relevant to the characteristics of Fabaceae.
- **Conclusion for Option 2**: This option is incorrect as it includes terms that do not describe Fabaceae.

4. **Analyzing Option 3**:
- **Estipulate**:
- Many Fabaceae plants have stipules, making this option incorrect.
- **Echinomorphic**:
- This term does not apply to the characteristics of Fabaceae.
- **Sandrus**:
- This is not a recognized term in relation to Fabaceae.
- **Conclusion for Option 3**: This option is incorrect.

5. **Analyzing Option 4**:
- **Alternate Leaves**:
- This can be true for some Fabaceae, but it is not a defining characteristic.
- **Bisexual**:
- Many flowers in Fabaceae are bisexual, but the other terms do not fit.
- **Bicapillary**:
- This term is not relevant to Fabaceae.
- **Conclusion for Option 4**: This option is incorrect.

### Final Answer:
The correct answer is **Option 1**: Pinnately Compound Leaf, Zygomorphic Flower, and Racemose Inflorescence.
