Options

A. Explant
B. Somaclones
C. Callus
D. Somatic hybrid

Answer

To solve the question, "If the protoplast of tomato is fused with potato protoplast and grown as a new plant, it will be known as," we will analyze the options provided and understand the concept of protoplast fusion.

### Step-by-Step Solution:

1. **Understanding Protoplast Fusion**:
- Protoplast fusion involves the merging of the protoplasts (the living part of the cell without the cell wall) of two different plant species. In this case, we are fusing the protoplasts of tomato and potato.

2. **Identifying the Process**:
- The process of fusing protoplasts from different species is known as **somatic hybridization**. This allows for the combination of genetic material from both plants, potentially resulting in a new plant with traits from both parent plants.

3. **Analyzing the Options**:
- **Explant**: This refers to any plant part used for propagation, not specifically related to protoplast fusion.
- **Somaclone**: These are plants derived from tissue culture techniques, not specifically from protoplast fusion.
- **Callus**: This is an unorganized mass of cells that can form in tissue culture but does not refer to the outcome of protoplast fusion.
- **Somatic Hybrid**: This term specifically refers to the new plant formed from the fusion of protoplasts of two different species.

4. **Conclusion**:
- Since the question asks for the term that describes the new plant formed from the fusion of tomato and potato protoplasts, the correct answer is **somatic hybrid**.

### Final Answer:
The new plant formed from the fusion of tomato and potato protoplasts will be known as a **somatic hybrid**.
