In Periplaneta, the cuticular lipid is secreted by

Options

A. Hypodermal cells
B. Oenocyte cell
C. Dermal gland cells
D. Basal cell

Answer

To answer the question regarding which cells in Periplaneta (the cockroach) secrete cuticular lipids, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Function of Cuticular Lipids**:
- Cuticular lipids play a crucial role in preventing water loss in cockroaches. This adaptation is vital for their survival, especially in terrestrial environments.

2. **Identify the Types of Cells**:
- In Periplaneta, several types of cells are involved in secretion processes, including hypodermal cells, oenocyte cells, dermal gland cells, and basal cells.

3. **Focus on Oenocyte Cells**:
- Oenocyte cells are specialized cells in cockroaches that are known for their role in lipid secretion. They are primarily responsible for producing and secreting the cuticular lipids.

4. **Confirm the Role of Oenocyte Cells**:
- In addition to secreting cuticular lipids, oenocyte cells also participate in detoxification processes, indicating their multifunctional role in the physiology of cockroaches.

5. **Conclude the Answer**:
- Based on the information gathered, we can conclude that the cuticular lipid in Periplaneta is secreted by oenocyte cells.

### Final Answer:
The cuticular lipid in Periplaneta (cockroach) is secreted by **oenocyte cells**.
