An animal cell differs from plant cells in not having

Options

A. Plastids
B. Cell wall
C. Glyoxysome
D. All of these

Answer

To answer the question "An animal cell differs from a plant cell in not having," we will compare the structures and organelles present in animal cells and plant cells.

### Step-by-Step Solution:

1. **Identify Key Organelles**: We need to identify specific organelles that are present in plant cells but absent in animal cells. The common organelles to consider are plastids, cell wall, and glyoxisomes.

2. **Plastids**:
- **Definition**: Plastids are double-membrane organelles found in plant cells.
- **Function**: They are involved in the manufacture and storage of food, such as chloroplasts which are responsible for photosynthesis.
- **Conclusion**: Animal cells do not have plastids.

3. **Cell Wall**:
- **Definition**: The cell wall is a rigid outer layer found in plant cells.
- **Composition**: It is primarily composed of cellulose, providing structural support and protection.
- **Conclusion**: Animal cells lack a cell wall and only have a flexible cell membrane.

4. **Glyoxisomes**:
- **Definition**: Glyoxisomes are specialized peroxisomes found in plant cells.
- **Function**: They are involved in the storage of fats and are particularly important during the germination of seeds.
- **Conclusion**: Glyoxisomes are absent in animal cells.

5. **Final Comparison**:
- Based on the above analysis, we can conclude that animal cells differ from plant cells in not having:
- Plastids
- Cell wall
- Glyoxisomes

### Final Answer:
An animal cell differs from a plant cell in not having plastids, a cell wall, and glyoxisomes.
