Answer

To solve the question "Phagosomes and pinosomes are collectively called," we can follow these steps:

### Step-by-Step Solution:

1. **Define Phagosomes**:
- Phagosomes are vesicles that form around particles that are engulfed by phagocytes. This process is known as phagocytosis.

2. **Define Pinosomes**:
- Pinosomes are also vesicles, but they are formed by the process of pinocytosis, which involves the engulfing of fluid and dissolved substances.

3. **Identify the Collective Term**:
- Both phagosomes and pinosomes are types of vesicles that result from different forms of endocytosis (phagocytosis and pinocytosis, respectively).

4. **Conclusion**:
- The collective term for phagosomes and pinosomes is **endosomes**. Endosomes refer to the vesicles formed during these processes.

### Final Answer:
Phagosomes and pinosomes are collectively called **endosomes**.
