Epidermis and epiblema are produced from
(a) Phellogen
(b) Calyptrogen
(c) Procambium
(d) Protoderm

Options

A. Phellogen
B. Calytrogen
C. Procambium
D. Protoderm

Answer

To solve the question of which tissue produces the epidermis and epiblema, we can follow these steps:

### Step 1: Understand the Definitions
- **Epidermis**: This is the outermost layer of cells found in stems, roots, and leaves. It serves as a protective barrier.
- **Epiblema**: This is a specific type of epidermis, usually a single layer of cells found primarily in roots.

### Step 2: Identify the Options
The options given are:
(a) Phellogen
(b) Calyptrogen
(c) Procambium
(d) Protoderm

### Step 3: Analyze Each Option
- **Phellogen**: This is the cork cambium that produces cork cells, not epidermis or epiblema.
- **Calyptrogen**: This is a tissue that contributes to the root cap, not directly involved in forming the epidermis or epiblema.
- **Procambium**: This tissue gives rise to vascular tissues (xylem and phloem), not epidermis or epiblema.
- **Protoderm**: This is the primary meristem that differentiates into the epidermis and epiblema.

### Step 4: Conclusion
From the analysis, we can conclude that both the epidermis and epiblema are produced from the **protoderm**. Therefore, the correct answer is:

**(d) Protoderm**
