Plant cell differs from animals cell by

Options

A. Presence of vacuoles
B. Presence of cell wall and chloroplast
C. Absence of cell wall
D. Absence of chloroplast.

Answer

**Step-by-Step Solution:**

1. **Identify the Cell Types**: Understand that both plant and animal cells are eukaryotic cells, meaning they have a true nucleus and membrane-bound organelles.

2. **Examine Vacuoles**:
- Both plant and animal cells contain vacuoles.
- In plant cells, there is typically one large central vacuole that plays a significant role in storage and maintaining turgor pressure.
- In animal cells, vacuoles are smaller and more numerous, serving less prominent functions.
- Conclusion: Vacuoles are present in both cell types, so they do not differentiate plant cells from animal cells.

3. **Analyze Cell Wall and Chloroplast**:
- **Cell Wall**:
- Plant cells have a rigid cell wall made primarily of cellulose, which provides structural support.
- Animal cells do not have a cell wall; they only have a flexible cell membrane.
- Conclusion: The presence of a cell wall is a key difference between plant and animal cells.
- **Chloroplast**:
- Chloroplasts are present in plant cells and are essential for photosynthesis, allowing plants to produce their own food.
- Animal cells lack chloroplasts and cannot perform photosynthesis.
- Conclusion: The presence of chloroplasts is another significant difference.

4. **Summarize the Differences**:
- Plant cells differ from animal cells primarily due to the presence of a cell wall and chloroplasts.
- Animal cells lack both a cell wall and chloroplasts.

5. **Final Conclusion**: The correct answer to the question is that plant cells differ from animal cells by the presence of a cell wall and chloroplasts.
