Options

A. Rough Endoplasmic Reticulum
B. Golgi complex
C. Smooth Endoplasmic Reticulum
D. Lysosomes

Answer

To solve the question regarding Leydig cells in a mammalian testis, we will analyze the characteristics and functions of these cells compared to other cells in the testis.

### Step-by-Step Solution:

1. **Understanding Leydig Cells**: Leydig cells, also known as interstitial cells, are located in the testis and are primarily responsible for the production of testosterone, a key male hormone.

2. **Identifying Key Functions**: The primary function of Leydig cells is the synthesis of steroid hormones, particularly testosterone. This process requires a significant amount of lipid synthesis, as steroids are derived from lipids.

3. **Cellular Organelles Involved**: To produce steroids, cells typically require certain organelles:
- **Smooth Endoplasmic Reticulum (Smooth ER)**: This organelle is crucial for lipid synthesis and metabolism. It is well-developed in steroid-producing cells like Leydig cells.
- **Rough Endoplasmic Reticulum (Rough ER)**: This organelle is involved in protein synthesis and is not as prominent in steroid-producing cells.
- **Golgi Complex**: This organelle is involved in the modification and packaging of proteins and lipids but is not the primary organelle for steroid synthesis.
- **Lysosomes**: These are involved in the breakdown of waste materials and cellular debris, not directly related to steroid hormone production.

4. **Comparative Analysis**: Given that Leydig cells are specialized for steroid hormone production, they will have a higher amount of smooth endoplasmic reticulum compared to other cell types in the testis, which are not primarily involved in hormone synthesis.

5. **Conclusion**: Therefore, the answer to the question is that Leydig cells will have more amount of **Smooth Endoplasmic Reticulum (option C)** compared to other cells in the mammalian testis.

### Final Answer:
C. Smooth ER
