All tissues except epidermis and vascular bundle constitute the __________

Options

A. Ground tissue system
B. Epidermal tissue system
C. Vascular tissue system
D. All

Answer

To solve the question "All tissues except epidermis and vascular bundle constitute the __________", we can follow these steps:

### Step 1: Understand the Types of Plant Tissues
Plant tissues are generally categorized into three main systems:
1. **Epidermal Tissue System** - This forms the outermost layer of the plant.
2. **Vascular Tissue System** - This includes xylem and phloem, which are responsible for the transport of water, nutrients, and food.
3. **Ground Tissue System** - This includes all other tissues that are not part of the epidermal or vascular systems.

### Step 2: Identify the Excluded Tissues
The question specifies that we are excluding:
- **Epidermis** (part of the epidermal tissue system)
- **Vascular Bundle** (which consists of xylem and phloem, part of the vascular tissue system)

### Step 3: Determine What Remains
Since we are excluding both the epidermis and the vascular bundle, we need to identify what remains. The remaining tissues in the plant are those that fall under the ground tissue system.

### Step 4: Conclusion
Therefore, the answer to the question is that all tissues except epidermis and vascular bundle constitute the **ground tissue system**.

### Final Answer:
All tissues except epidermis and vascular bundle constitute the **ground tissue system**.
