A fusion product arising out of a fusion between a protoplast containing nucleus and a protoplast without nucleus, is known as

Options

A. hybrid
B. cybrid
C. nucleoid
D. monohybrid

Answer

To solve the question regarding the fusion product arising from the fusion between a protoplast containing a nucleus and a protoplast without a nucleus, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Protoplasts**:
- A protoplast is a plant cell that has had its cell wall removed. It consists of the cell membrane, cytoplasm, and nucleus (if present).

2. **Identifying the Types of Protoplasts**:
- In this scenario, we have two types of protoplasts:
- One protoplast contains a nucleus.
- The other protoplast does not contain a nucleus.

3. **Fusion of Protoplasts**:
- When these two protoplasts are fused together, the resulting product is a combination of the cytoplasm and cellular components of both protoplasts.

4. **Naming the Fusion Product**:
- The fusion product formed from the protoplast with a nucleus and the protoplast without a nucleus is specifically termed a **cybrid**.
- A cybrid is a hybrid cell that contains cytoplasmic components from one cell and nuclear components from another.

5. **Conclusion**:
- Therefore, the answer to the question is that the fusion product is known as a **cybrid**.

### Final Answer:
The fusion product arising out of a fusion between a protoplast containing a nucleus and a protoplast without a nucleus is known as a **cybrid**.
