The phyllotaxy in which two leaves arise from a bud at each node is

Options

A. whorled
B. alternate
C. opposite
D. none of these

Answer

To solve the question regarding the type of phyllotaxy in which two leaves arise from a bud at each node, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Phyllotaxy**: Phyllotaxy refers to the arrangement of leaves on a plant stem. It is important to know the different types of phyllotaxy to answer the question correctly.

2. **Identify the Types of Phyllotaxy**: The main types of phyllotaxy are:
- **Alternate Phyllotaxy**: In this arrangement, leaves arise from different nodes, and they are positioned alternately around the stem.
- **Opposite Phyllotaxy**: In this arrangement, two leaves arise from the same node and are positioned directly opposite each other.

3. **Analyze the Question**: The question specifies that two leaves arise from a bud at each node. This indicates that both leaves are coming from the same node.

4. **Determine the Correct Type**: Since the leaves are arising from the same node, this matches the definition of **Opposite Phyllotaxy**. In contrast, alternate phyllotaxy would involve leaves coming from different nodes.

5. **Conclude the Answer**: Therefore, the phyllotaxy in which two leaves arise from a bud at each node is called **Opposite Phyllotaxy**.

### Final Answer:
The phyllotaxy in which two leaves arise from a bud at each node is **Opposite Phyllotaxy**.
