Ingestion of solid food by plasma membranes is called

Options

A. Endosmosis
B. Pinocytosis
C. Cytokinesis
D. Phagocytosis

Answer

To solve the question "Ingestion of solid food by plasma membranes is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for the specific term that describes the process by which plasma membranes ingest solid food.

2. **Evaluate the Options**:
- **Option 1: Endoosmosis**: This term refers to the movement of water into cells, particularly when they are in a hypotonic solution. This is not related to the ingestion of solid food.
- **Option 2: Pinocytosis**: This process is known as "cell drinking," where cells ingest liquid substances. Since the question specifies solid food, this option is incorrect.
- **Option 3: Cytokinesis**: This term refers to the division of the cytoplasm during cell division. It does not pertain to the ingestion of food, so this option is also incorrect.
- **Option 4: Phagocytosis**: This is the correct term. Phagocytosis is the process by which cells ingest solid particles, including food.

3. **Select the Correct Answer**: Based on the evaluations, the correct answer is **Phagocytosis**.

### Final Answer:
Ingestion of solid food by plasma membranes is called **Phagocytosis**.
