A special type of facilitated diffusion related to movement of solvents only through living systems is called

Options

A. Imbitition
B. Osmosis
C. Plasmolysis
D. Embolism

Answer

To solve the question, "A special type of facilitated diffusion related to movement of solvents only through living systems is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a specific type of facilitated diffusion that involves the movement of solvents in living systems.

2. **Identify Key Terms**: The key terms here are "facilitated diffusion," "movement of solvents," and "living systems."

3. **Review the Options**: The options given are:
- Imbibition
- Osmosis
- Plasmolysis
- Embolism

4. **Analyze Each Option**:
- **Imbibition**: This refers to the absorption of water by solids, particularly plant tissues, and is not a type of diffusion. Therefore, this option is incorrect.
- **Osmosis**: This is the movement of water (solvent) through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. This process is indeed a special type of facilitated diffusion and occurs in living systems. Therefore, this option is correct.
- **Plasmolysis**: This is the process where cells lose water in a hypertonic solution, leading to cell shrinkage. It is a consequence of osmosis, not a type of diffusion itself. Thus, this option is incorrect.
- **Embolism**: This term refers to a blockage in a blood vessel and is unrelated to the movement of solvents in living systems. Therefore, this option is incorrect.

5. **Conclusion**: After analyzing all the options, the correct answer to the question is **osmosis**.

### Final Answer:
The correct answer is **osmosis**.
