Trichogen cells of epidermis of Cockroach produce

Options

A. Exocuticle
B. Endocuticle
C. Bristles
D. Membrane around bristles

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks what the trichogen cells of the epidermis in cockroaches produce.

2. **Identifying the Location**: The trichogen cells are located in the epidermis, which is a layer of columnar epithelial cells situated beneath the cuticle of the cockroach.

3. **Function of Trichogen Cells**: Trichogen cells are specialized cells that have distinct structural and functional characteristics.

4. **Production by Trichogen Cells**: The primary function of trichogen cells is to produce bristles. These bristles serve as movable sensory appendages for the cockroach.

5. **Evaluating the Options**: The options provided are:
- Exocuticle
- Endocuticle
- Bristles
- Membrane around the bristles

Since we established that trichogen cells produce bristles, we can eliminate the other options (exocuticle, endocuticle, and membrane around the bristles) as they are not produced by trichogen cells.

6. **Conclusion**: The correct answer is that trichogen cells of the epidermis of cockroaches produce **bristles**.

### Final Answer:
**Bristles**
