Which among the following are fat secreting cells present in the haemocoel of cockroach

Options

A. Trophocytes
B. Urate cells
C. Mycetocytes
D. Oenocytes

Answer

To answer the question regarding the fat-secreting cells present in the hemocoel of the cockroach, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for fat-secreting cells found in the hemocoel of cockroaches. The hemocoel is the primary body cavity in insects, containing hemolymph (blood).

2. **Identifying the Options**: The options provided are:
- A) Trophocytes
- B) Urate cells
- C) Mycetocytes
- D) Enocytes

3. **Analyzing Each Option**:
- **A) Trophocytes**: These are indeed fat-secreting cells in insects, including cockroaches. They store food in the form of fats, glycogen, and proteins. They are found in the hemolymph of cockroaches, making this option a strong candidate.

- **B) Urate Cells**: These cells are involved in the elimination of nitrogenous waste. They do not secrete fat, which makes this option incorrect.

- **C) Mycetocytes**: These cells assist in the synthesis of amino acids and proteins with the help of symbiotic bacteria. They are not primarily involved in fat secretion, so this option is also incorrect.

- **D) Enocytes**: These cells are involved in various metabolic activities, including detoxification and lipid processing, but they are not specifically fat-secreting cells. Thus, this option is incorrect as well.

4. **Conclusion**: Based on the analysis, the correct answer is **A) Trophocytes**, as they are the fat-secreting cells present in the hemocoel of cockroaches.

### Final Answer:
**A) Trophocytes**
