Phagocytosis and pinocytosis are collectively termed as

Options

A. Endocytosis
B. Suspension feeding
C. Omnivores
D. Mucous trap

Answer

**Step-by-Step Solution:**

1. **Understanding the Terms**:
- Phagocytosis and pinocytosis are processes that involve the intake of substances by cells. Phagocytosis refers to the uptake of solid particles, while pinocytosis refers to the uptake of liquids.

2. **Identifying the Type of Transport**:
- Both phagocytosis and pinocytosis fall under a broader category of transport known as endocytosis. Endocytosis is the process by which cells engulf external substances, bringing them into the cell.

3. **Differentiating Between Types of Bulk Transport**:
- Bulk transport can be categorized into two main types:
- **Exocytosis**: The process of expelling substances from the cell.
- **Endocytosis**: The process of taking substances into the cell.

4. **Classifying Phagocytosis and Pinocytosis**:
- Since both phagocytosis (cell eating) and pinocytosis (cell drinking) involve the intake of substances into the cell, they are both classified under endocytosis.

5. **Conclusion**:
- Therefore, phagocytosis and pinocytosis are collectively termed as **endocytosis**.

**Final Answer**: Endocytosis
