Articulated latex vessels occur in

Options

A. Hevea
B. Colotropis
C. Euphorbia
D. Tamarindus

Answer

To solve the question "Articulated latex vessels occur in," we will analyze the provided options one by one:

### Step-by-Step Solution:

1. **Understanding the Question**: We need to identify which of the given plants contains articulated latex vessels.

2. **Analyzing the Options**:
- **Option 1: Hevea**:
- Hevea, commonly known for rubber production, contains articulated latex vessels. These vessels are formed by the fusion of several cells and are arranged in parallel, creating a network known as a choanocytic network.
- Therefore, Hevea is a strong candidate for containing articulated latex vessels.

- **Option 2: Calotropis**:
- In Calotropis, the latex vessels do not form articulated structures. Instead, the cells originate as minute structures that undergo quick elongation and branching, resulting in non-articulated latex vessels.

- **Option 3: Euphorbia**:
- Similar to Calotropis, Euphorbia also has non-articulated latex vessels. The cells here also originate as minute structures and do not form articulated vessels.

- **Option 4: Tamarindus**:
- Tamarindus, like the previous two options, does not have articulated latex vessels. The latex cells in Tamarindus are also non-articulated.

3. **Conclusion**: After analyzing all the options, we find that articulated latex vessels are present only in Hevea. Therefore, the correct answer is **Hevea**.

### Final Answer:
**Articulated latex vessels occur in Hevea.**
