A cell lacking cell wall would also lack

Options

A. Chloroplast
B. ER
C. mitochondria
D. biomembrane

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks what a cell lacking a cell wall would also lack. This indicates that we need to identify what types of cells typically have a cell wall and what structures are associated with those cells.

2. **Identifying Cell Types**:
- **Plant Cells**: Have a cell wall made of cellulose.
- **Fungal Cells**: Have a cell wall made of chitin.
- **Animal Cells**: Do not have a cell wall.

3. **Analyzing the Options**:
- **Chloroplast**: Present in plant cells for photosynthesis.
- **Endoplasmic Reticulum**: Present in both animal and plant cells; involved in protein and lipid synthesis.
- **Mitochondria**: Present in both animal and plant cells; known as the powerhouse of the cell for energy production.
- **Biomembrane**: Also known as the cell membrane or plasma membrane; present in all cells, including animal cells.

4. **Conclusion**: Since we are discussing a cell that lacks a cell wall, we are referring to an animal cell. Animal cells do not have chloroplasts, which are specifically found in plant cells for photosynthesis. Therefore, a cell lacking a cell wall would also lack chloroplasts.

5. **Final Answer**: The correct answer is **Chloroplast**.
