The outermost primary meristem gives rise to

Options

A. Epidermis
B. Procambium
C. Ground meristem
D. All of the above

Answer

To answer the question "The outermost primary meristem gives rise to," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Primary Meristems**:
- Primary meristems are responsible for the growth of plants. They are found at the tips of roots and shoots and are involved in the primary growth of the plant.

2. **Identifying the Outermost Primary Meristem**:
- The primary meristem is divided into three parts: protoderm, ground meristem, and procambium. Among these, the outermost one is the protoderm.

3. **Function of the Protoderm**:
- The protoderm is specifically responsible for forming the outer layer of the plant.

4. **Tissue Derived from Protoderm**:
- The protoderm gives rise to the epidermal tissue system, which is the outer protective layer of the plant.

5. **Conclusion**:
- Therefore, the outermost primary meristem, which is the protoderm, gives rise to the epidermis.

### Final Answer:
The outermost primary meristem gives rise to the epidermal tissue system (epidermis).
