Formation of phagosomes in the cell is the result of :-

Options

A. Egestion of solid materials
B. Ingestion of liquid materials
C. Ingestion of solid materials
D. Egestion of liquid materials

Answer

**Step-by-Step Solution:**

1. **Understanding Phagosomes**: Phagosomes are specialized structures within cells that form when a cell engulfs solid food particles. They are essentially food vacuoles that arise during the process of phagocytosis.

2. **Phagocytosis Process**: The process of phagocytosis involves the extension of the cell membrane around a solid particle, which is often facilitated by structures called pseudopodia. This is commonly observed in organisms such as amoeba.

3. **Formation of Phagosomes**: When an amoeba encounters a food particle, it extends its pseudopodia around the particle. This action leads to the engulfment of the particle, resulting in the formation of a phagosome (food vacuole).

4. **Role of Lysosomes**: Once the phagosome is formed, it can fuse with lysosomes, which contain digestive enzymes. This fusion allows the enzymes to break down the food particles within the phagosome.

5. **Waste Elimination**: After digestion, the waste materials are expelled from the cell through a process known as exocytosis.

6. **Conclusion**: The formation of phagosomes is a result of the ingestion of solid food particles, which is a characteristic of holozoic nutrition commonly seen in protists.

**Final Answer**: The formation of phagosomes in the cell is the result of the ingestion of solid food particles, a process known as phagocytosis.
