Which of the following organelles is common to plants and animals?

Options

A. Chloroplast
B. Centriole
C. Mitochondria
D. Cell wall

Answer

To determine which organelle is common to both plants and animals, we can analyze the options provided:

1. **Chloroplast**:
- Chloroplasts are organelles responsible for photosynthesis, a process that allows plants to convert sunlight into energy.
- They are found only in plant cells and some algae, not in animal cells.

2. **Centriole**:
- Centrioles are involved in cell division and are primarily found in animal cells.
- They are absent in plant cells, making them not common to both.

3. **Mitochondria**:
- Mitochondria are known as the "powerhouse of the cell" because they generate ATP through cellular respiration.
- They are present in both plant and animal cells, making them the common organelle.

4. **Cell Wall**:
- The cell wall provides structure and rigidity to plant cells and is not found in animal cells.
- Therefore, it is not common to both.

Based on this analysis, the organelle that is common to both plants and animals is **Mitochondria**.

### Final Answer:
**Mitochondria** (Option 3) is the organelle that is common to both plants and animals.
