Solid particles are ingested by pinocytosis.

Answer

### Step-by-Step Solution:

1. **Understanding the Terms**:
- Pinocytosis and phagocytosis are both forms of endocytosis, which is the process by which cells internalize substances from their external environment.
- Pinocytosis is often referred to as "cell drinking," where the cell takes in liquid droplets.
- Phagocytosis is referred to as "cell eating," where the cell engulfs solid particles.

2. **Analyzing the Statement**:
- The statement claims that solid particles are ingested by pinocytosis.
- Since pinocytosis involves the ingestion of liquids, this statement is incorrect.

3. **Identifying the Correct Process**:
- The correct process for the ingestion of solid particles is phagocytosis.
- In phagocytosis, cells engulf large particles such as cell debris or microorganisms.

4. **Conclusion**:
- Therefore, the statement "Solid particles are ingested by pinocytosis" is false. The correct statement would be "Solid particles are ingested by phagocytosis."
