Identify in order, the plants showing alternate, opposite and whorled phyllotaxy

Options

A. China rose, Calotropis and Nerium
B. China rose, Nerium and Calotropis
C. Nerium, China rose, Calotropis
D. Nerium, Calotropis, China rose

Answer

To solve the question of identifying plants that exhibit alternate, opposite, and whorled phyllotaxy, we can follow these steps:

### Step 1: Understand Phyllotaxy
Phyllotaxy refers to the arrangement of leaves on a plant stem. There are three main types:
- **Alternate Phyllotaxy**: One leaf per node, arranged alternately along the stem.
- **Opposite Phyllotaxy**: Two leaves per node, positioned directly opposite each other.
- **Whorled Phyllotaxy**: Three or more leaves per node, arranged in a circle around the stem.

### Step 2: Identify Plants for Each Type
1. **Alternate Phyllotaxy**:
- **China Rose (Hibiscus rosa-sinensis)** is known for having an alternate arrangement of leaves.

2. **Opposite Phyllotaxy**:
- **Calotropis** (often referred to as Calopteris in some contexts) exhibits opposite leaf arrangement, where two leaves arise at each node.

3. **Whorled Phyllotaxy**:
- **Nerium (Oleander)** is characterized by whorled phyllotaxy, where multiple leaves emerge from a single node.

### Step 3: Compile the Information
Now we can compile the information about the plants and their respective phyllotaxy:
- **China Rose**: Alternate
- **Calotropis**: Opposite
- **Nerium**: Whorled

### Step 4: Determine the Correct Order
Based on the identified phyllotaxy:
- The order of plants showing alternate, opposite, and whorled phyllotaxy is:
- **China Rose (Alternate)**
- **Calotropis (Opposite)**
- **Nerium (Whorled)**

### Final Answer
The correct order of plants showing alternate, opposite, and whorled phyllotaxy is:
**A. China Rose, Calotropis, and Nerium.**
