Animal and plant cells differ from each other in a number of ways.
Which cell organelle is absent in animal cells?

Options

A. Mitochondria
B. Chloroplast
C. Vacuole
D. Nucleus

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks which cell organelle is absent in animal cells but present in plant cells.

2. **Identify Key Differences**: Recognize that animal and plant cells have several differences in their structures and organelles.

3. **List the Organelles**: Consider the organelles that are commonly found in both types of cells, such as mitochondria, nucleus, and vacuoles, and identify those that are unique to plant cells.

4. **Evaluate the Options**:
- **Mitochondria**: Present in both animal and plant cells; responsible for energy production.
- **Chloroplast**: This organelle is primarily found in plant cells and is responsible for photosynthesis. It is absent in animal cells.
- **Vacuole**: While plant cells have large central vacuoles, animal cells can have smaller vacuoles, so this is not a definitive answer.
- **Nucleus**: Present in both animal and plant cells; contains genetic material.

5. **Conclusion**: The organelle that is absent in animal cells and present in plant cells is the **chloroplast**.

**Final Answer**: Chloroplast
