What are the epidermal cells producing movable bristles in cockroach known as ?

Options

A. Trichocysts
B. Interstitial cells
C. Trichogen cells
D. Oenocytes

Answer

To answer the question about the epidermal cells that produce movable bristles in cockroaches, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the specific type of epidermal cells in cockroaches that are responsible for producing movable bristles.

2. **Identifying the Options**: The options provided are:
- a) Trichocost
- b) Interstitial cells
- c) Trichogen cells
- d) Wino sites

3. **Analyzing the Options**:
- **Trichocost**: This term does not relate to the production of movable bristles in cockroaches.
- **Interstitial cells**: These cells are typically involved in other functions and are not specifically known for producing bristles.
- **Trichogen cells**: These are specialized epidermal cells that are known to produce movable bristles (setae) in insects, including cockroaches.
- **Wino sites**: This term does not correspond to any known cell type related to bristle production.

4. **Selecting the Correct Answer**: Based on the analysis, the correct answer is **c) Trichogen cells**. These cells are modified epidermal cells specifically responsible for the production of movable bristles in cockroaches.

5. **Conclusion**: Therefore, the epidermal cells producing movable bristles in cockroaches are known as **trichogen cells**.
