Mustard contains

Options

A. Alternate phyllotaxy and actinomorphic flower
B. Opposite phyllotaxy and zygomorphic flower
C. Whorled phyllotaxy and actinomorphic flower
D. Opposite phyllotaxy and actinomorphic flower

Answer

To solve the question about what mustard contains, we will break it down into two main components: phyllotaxy (the arrangement of leaves) and the symmetry of the flower.

### Step-by-Step Solution:

1. **Understanding Phyllotaxy**:
- Phyllotaxy refers to the arrangement of leaves on the stem of a plant.
- There are three main types of phyllotaxy:
- **Alternate Phyllotaxy**: Leaves are arranged alternately at each node.
- **Opposite Phyllotaxy**: A pair of leaves arises at each node, positioned opposite to each other.
- **Whorled Phyllotaxy**: More than two leaves arise at each node.

2. **Identifying the Type of Phyllotaxy in Mustard**:
- Mustard exhibits **alternate phyllotaxy**, where leaves are arranged alternately along the stem. This is a characteristic feature of mustard plants.

3. **Understanding Flower Symmetry**:
- Flower symmetry refers to how the flower can be divided into equal halves.
- There are two main types of flower symmetry:
- **Actinomorphic Flower**: The flower can be divided into two equal halves in multiple ways (radial symmetry).
- **Zygomorphic Flower**: The flower can only be divided into two equal halves in one specific way (bilateral symmetry).

4. **Identifying the Type of Flower Symmetry in Mustard**:
- Mustard flowers are **actinomorphic**, meaning they can be divided into two equal halves in multiple ways.

5. **Conclusion**:
- Based on the above analysis, mustard contains **alternate phyllotaxy** and **actinomorphic flowers**. Therefore, the correct option is the first one.

### Final Answer:
Mustard contains alternate phyllotaxy and actinomorphic flowers.
