Vascular bundles are conjoint, bicollateral and open in :

Options

A. Wheat stem
B. Pea root
C. Wheat root
D. Cucurbita stem

Answer

To solve the question "Vascular bundles are conjoint, bicollateral and open in:", we need to analyze the characteristics of vascular bundles in different types of plants. Here’s a step-by-step solution:

### Step 1: Understand Vascular Bundles
Vascular bundles are structures in plants that contain xylem and phloem, which are responsible for the transport of water, nutrients, and food. They can be classified based on their arrangement and the presence of cambium.

**Hint:** Remember that vascular bundles are essential for the transport system in plants.

### Step 2: Identify Types of Vascular Bundles
- **Conjoint:** Xylem and phloem are found together in the same bundle.
- **Bicollateral:** Phloem is present on both sides of the xylem.
- **Open:** Cambium is present, allowing for secondary growth.

**Hint:** Focus on the definitions of conjoint, bicollateral, and open vascular bundles.

### Step 3: Analyze the Options
1. **Wheat Stem:** Wheat is a monocot, and its vascular bundles are conjoint, collateral, and closed (no cambium).
2. **Pea Root:** Roots generally do not have the same vascular bundle arrangement as stems.
3. **Wheat Root:** Similar to the pea root, roots do not exhibit the same vascular bundle characteristics as stems.
4. **Cucurbita Stem:** Cucurbita is a dicot plant, and its vascular bundles are conjoint, bicollateral, and open.

**Hint:** Compare the characteristics of each option with the definitions of vascular bundles.

### Step 4: Conclusion
Based on the analysis, the only option that fits the description of having vascular bundles that are conjoint, bicollateral, and open is **Cucurbita Stem**.

**Final Answer:** The correct option is **Cucurbita Stem**.
