Chlorophyll containing fleshy cylindrical structure found in Euphrobia re modified

Options

A. Roots
B. Fruit
C. Leaves
D. Stem

Answer

To answer the question regarding the chlorophyll-containing fleshy cylindrical structure found in Euphorbia, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Plant Type**: Recognize that Euphorbia is a genus of flowering plants that often thrive in arid or dry conditions.

2. **Understand the Environmental Adaptation**: Note that plants in arid conditions need to adapt to conserve water. One common adaptation is the modification of certain plant structures.

3. **Determine the Structure in Question**: The fleshy cylindrical structures in Euphorbia are not roots or fruits but are actually modified stems. These structures are designed to store water and nutrients.

4. **Recognize the Role of Chlorophyll**: The presence of chlorophyll in these structures indicates that they can perform photosynthesis, which is the process by which plants convert light energy into chemical energy (food).

5. **Conclude the Modification Type**: Since the fleshy cylindrical structures are green, photosynthetic, and serve the purpose of water storage and food production, we conclude that they are modified stems.

### Final Answer:
The chlorophyll-containing fleshy cylindrical structures found in Euphorbia are modifications of the stem.
