Floral formula of mustard is

Answer

To derive the floral formula of mustard, we need to break down the components of the flower and represent them in a systematic way. Here’s a step-by-step solution:

### Step 1: Identify the Parts of the Flower
The floral formula includes the following parts:
- **Calyx (sepals)**
- **Corolla (petals)**
- **Androecium (stamens)**
- **Gynoecium (carpels)**

### Step 2: Determine the Number of Each Part
For mustard (Brassica species):
- **Calyx**: Mustard has 4 sepals, which are usually fused. This is represented as **2 + 2** (indicating two pairs of sepals).
- **Corolla**: Mustard has 4 petals, which are distinct. This is represented as **4**.
- **Androecium**: Mustard has 6 stamens, typically arranged in two whorls of 4 and 2. This is represented as **2** (the outer whorl) + **4** (the inner whorl).
- **Gynoecium**: Mustard has 2 fused carpels, which is represented as **(2)** indicating that they are fused together.

### Step 3: Write the Floral Formula
Combining all these components, the floral formula for mustard can be written as:
- **Floral Formula of Mustard**:
- **K(2 + 2) C4 A(2 + 4) G(2)**

### Step 4: Interpretation of the Floral Formula
- **K**: Represents the calyx (sepals).
- **C**: Represents the corolla (petals).
- **A**: Represents the androecium (stamens).
- **G**: Represents the gynoecium (carpels).
- The numbers indicate the quantity of each part, and the parentheses indicate fusion.

### Final Floral Formula
Thus, the complete floral formula for mustard is:
- **K(2 + 2) C4 A(2 + 4) G(2)**
