1. **Identify the Structure**: In frogs, the urinary bladder is a specific organ that plays a crucial role in the excretion of waste products.

2. **Characteristics of the Urinary Bladder**: The urinary bladder in frogs is described as being transparent. This transparency is an important feature that can help in identifying the organ.

3. **Location**: The urinary bladder is located on the ventral side of the cloaca. Understanding its anatomical position is essential for recognizing its relationship with other organs.

4. **Function**: The primary function of the urinary bladder is to store waste products before excretion. It acts as a reservoir for urine, allowing the frog to manage its waste efficiently.

5. **Structure**: The urinary bladder has a bilobed structure, which means it is divided into two lobes. This bilobed nature increases the surface area, facilitating better storage and filtration of waste products.

6. **Conclusion**: Based on the characteristics and functions described, we can conclude that the urinary bladder in frogs is bilobed in structure.

### Final Answer:
