List three special processes which are involved in the bulk transport of materials in and out of the animal cells.

Explanation

**Step-by-Step Solution:**

1. **Understanding Bulk Transport**: Bulk transport refers to the movement of large quantities of materials in and out of cells. In animal cells, this process is primarily managed by the plasma membrane, which is semi-permeable.

2. **Identifying the Processes**: There are three main processes involved in the bulk transport of materials in and out of animal cells:
- **Endocytosis**: This is the process by which cells take in substances from the outside environment. It can be further divided into:
- **Phagocytosis**: Often referred to as "cellular eating," this process involves the engulfing of large particles or cells.
- **Pinocytosis**: Known as "cellular drinking," this process involves the intake of liquids and small particles.
