Most accepted nature of protoplasm is

Options

A. Particulate nature
B. Sol - Gel nature
C. Alveolar nature
D. Fibrillar nature

Answer

To determine the most accepted nature of protoplasm, we will analyze the given options based on the characteristics of protoplasm.

### Step-by-Step Solution:

1. **Understanding Protoplasm**:
- Protoplasm is often referred to as the "physical basis of life" because it contains all the living components of a cell, including the cytoplasm and the nucleus, but excluding the cell wall.

2. **Physical Nature of Protoplasm**:
- Protoplasm is described as a translucent, semi-viscous fluid. This means it is not completely transparent, but allows some light to pass through.

3. **Forms of Protoplasm**:
- Due to its semi-viscous nature, protoplasm can exist in a colloidal state, which can be described as a "sol" (liquid) or "gel" (solid-like) form. This indicates that protoplasm does not exist purely as a solid or a liquid.

4. **Evaluating the Options**:
- **Particulate Nature**: This suggests a solid structure, which does not accurately describe protoplasm. Therefore, this option is incorrect.
- **Soil Gel Nature**: This accurately reflects the semi-viscous and colloidal nature of protoplasm, making this option correct.
- **Arbolar Nature**: This implies a branched or tree-like structure, which is not characteristic of protoplasm. Thus, this option is incorrect.
- **Fibrillar Nature**: This suggests a fibrous structure, which does not represent protoplasm. Hence, this option is also incorrect.

5. **Conclusion**:
- The most accepted nature of protoplasm is **"soil gel nature"**.

### Final Answer:
The most accepted nature of protoplasm is **soil gel nature**.
