Streaming of cytoplasm within a living cell is

Options

A. Homeostasis
B. Cyclosis
C. Diffusion
D. Osmoregulation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the term that describes the streaming of cytoplasm within a living cell. We need to identify the correct term from the provided options: homeostasis, cyclosis, diffusion, and osmoregulation.

2. **Defining Cytoplasmic Streaming**: Cytoplasmic streaming, also known as protoplasmic streaming, refers to the movement of the fluid substance (cytoplasm) within a cell. This movement is crucial for distributing nutrients, proteins, and organelles throughout the cell.

3. **Analyzing the Options**:
- **Homeostasis**: This term refers to the maintenance of stable internal conditions in an organism. It does not specifically relate to the movement of cytoplasm.
- **Cyclosis**: This is the correct term for the streaming of cytoplasm within a living cell. It describes the movement of cytoplasmic fluid that facilitates the distribution of materials within the cell.
- **Diffusion**: This process involves the movement of substances from an area of higher concentration to an area of lower concentration. While it relates to movement, it does not specifically refer to cytoplasmic streaming.
- **Osmoregulation**: This term refers to the regulation of water and solute concentrations in cells and organisms. It is not related to cytoplasmic streaming.

4. **Conclusion**: After analyzing the definitions and relevance of each option, we conclude that the correct answer is **cyclosis**. Therefore, the streaming of cytoplasm within a living cell is known as cyclosis.

**Final Answer**: The streaming of cytoplasm within a living cell is called **cyclosis**.
