Diploxylic vascular bundles are found in

Options

A. Pteris
B. Selaginella
C. Funaria
D. Cycas

Answer

To answer the question about where diploxylic vascular bundles are found, we can follow these steps:

### Step 1: Understand the term "diploxylic"
Diploxylic vascular bundles refer to a specific arrangement of xylem in vascular plants. In this arrangement, there are two distinct types of xylem tissues present: one that is centripetal (towards the center) and another that is centrifugal (away from the center).

**Hint:** Remember that "diploxylic" indicates a dual structure in the xylem.

### Step 2: Analyze the options provided
The options given are:
1. Teres
2. Selaginella
3. Fenaria
4. Cycus

We need to identify which of these options is known to have diploxylic vascular bundles.

**Hint:** Look for plants that are known for their unique vascular structures, particularly those that exhibit secondary growth.

### Step 3: Identify the plant with diploxylic vascular bundles
From the options:
- **Teres**: This plant does not exhibit diploxylic vascular bundles.
- **Selaginella**: This is a type of lycopod and also does not have diploxylic vascular bundles.
- **Fenaria**: This is not known for diploxylic vascular bundles.
- **Cycus**: This is a genus of cycads, which are known to have diploxylic vascular bundles due to their secondary growth and the arrangement of xylem.

**Hint:** Focus on cycads when considering plants that have complex vascular systems.

### Step 4: Conclusion
Based on the analysis, the correct answer is that diploxylic vascular bundles are found in **Cycus**.

**Final Answer:** Diploxylic vascular bundles are found in **Cycus**.
