A plant cell without cell wall is called

Options

A. proplast
B. protoplast
C. nucleoplasm
D. explant.

Explanation

To answer the question "A plant cell without cell wall is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Plant Cell Structure**:
- A plant cell consists of several components, including a cell wall, cell membrane (plasma membrane), cytoplasm, and organelles such as the nucleus.

2. **Identifying the Components**:
- The outermost layer of a plant cell is the cell wall, which provides structure and protection. Beneath the cell wall is the cell membrane, which controls the movement of substances in and out of the cell.

3. **Defining Protoplast**:
- When we refer to a plant cell without its cell wall, we are left with the cell membrane, cytoplasm, and the nucleus along with other organelles. Collectively, these components are known as the **protoplast**.

4. **Evaluating the Options**:
- The options given are:
- Protoplast
- Proplast
- Nucleoplast
- Explant
- Based on our understanding, the term that correctly describes a plant cell without a cell wall is **protoplast**.

5. **Conclusion**:
- Therefore, the correct answer to the question is **protoplast**.

### Final Answer:
A plant cell without a cell wall is called **protoplast**.
