Which of the following is incorrectly paired with its funtction ?

Options

A. Seminiferous tubules - add fluid containing mucus fructose , and prostaglandins to semen
B. Scrotum - encases testes and suspends them below abdominal cavity
C. Epididymis - stores sperm
D. Prostate gland -adds alkaline secretion to semen

Answer

To determine which of the following options is incorrectly paired with its function, we will analyze each option step by step.

### Step 1: Analyze Option 1 - Seminiferous Tubule
- **Function Given**: Adds fluid containing mucus, fructose, and prostaglandin.
- **Actual Function**: The seminiferous tubules are responsible for the production and maturation of sperm. They do not add fluids to semen; that function is performed by accessory glands such as the seminal vesicles and prostate gland.
- **Conclusion**: This option is incorrectly paired.

### Step 2: Analyze Option 2 - Scrotum
- **Function Given**: Encases the testis and suspends it below the abdominal cavity.
- **Actual Function**: The scrotum does indeed encase the testes and helps maintain a cooler temperature necessary for sperm production.
- **Conclusion**: This option is correctly paired.

### Step 3: Analyze Option 3 - Epididymis
- **Function Given**: Connects the testicles with vas deferens and transports and stores sperm cells.
- **Actual Function**: The epididymis is responsible for storing and maturing sperm before they are transported through the vas deferens.
- **Conclusion**: This option is correctly paired.

### Step 4: Analyze Option 4 - Prostate Gland
- **Function Given**: Adds alkaline secretion in semen.
- **Actual Function**: The prostate gland does secrete an alkaline fluid that helps protect and nourish sperm in the semen.
- **Conclusion**: This option is correctly paired.

### Final Conclusion
- The incorrect pairing is **Option 1: Seminiferous Tubule**.
