Number of leaves at each node in Calotropis

Options

A. 1
B. 2
C. 3
D. Many

Answer

To determine the number of leaves at each node in Calotropis, follow these steps:

1. **Understand the Plant's Characteristics**: Recognize that Calotropis is a genus of flowering plants commonly known as milkweeds. This is important as it provides context for the plant's morphology.

2. **Identify the Leaf Arrangement**: The key to answering the question lies in the arrangement of leaves on the stem. In Calotropis, the arrangement is described as "opposite phyllotaxy."

3. **Define Opposite Phyllotaxy**: In plants with opposite phyllotaxy, there are two leaves that arise from the same node, positioned directly across from each other.

4. **Conclude the Number of Leaves**: Since Calotropis exhibits opposite phyllotaxy, we conclude that there are 2 leaves at each node.

5. **Select the Correct Option**: Based on the analysis, the correct answer is option B, which states that there are 2 leaves at each node in Calotropis.

### Final Answer:
The number of leaves at each node in Calotropis is 2 (Option B).
