A protoplast is a cell

Options

A. without plasma membrane
B. without nucleus
C. undergiong division
D. without cell wall

Answer

### Step-by-Step Solution:

1. **Understanding the Cell Structure**:
- A typical plant cell consists of various components, including a cell wall, plasma membrane, cytoplasm, and nucleus. The cell wall is a rigid outer layer that provides structure and protection.

2. **Identifying the Protoplast**:
- A protoplast is defined as a cell that has had its cell wall removed. This can be achieved through various methods, such as chemical treatments, enzymatic action, or mechanical means.

3. **Components of the Protoplast**:
- Once the cell wall is removed, what remains is the protoplast, which includes:
- The plasma membrane (or cell membrane)
- The cytoplasm (the gel-like substance within the cell)
- The nucleus, which contains the cell's genetic material (DNA).

4. **Types of Cells that Can Form Protoplasts**:
- Protoplasts can be derived from different types of cells that have a cell wall, including:
- Plant cells
- Fungal cells
- Bacterial cells

5. **Conclusion**:
- Therefore, a protoplast is essentially a cell (plant, fungal, or bacterial) that lacks its cell wall, retaining only the inner structures.
