Which of the following cell organelle is not present in plant cells but present in the animal cell?

Options

A. Cell wall
B. Plastids
C. Central vacuole
D. Centrioles

Answer

To solve the question of which cell organelle is not present in plant cells but is present in animal cells, we will analyze each of the given options step by step.

### Step 1: Analyze the options
The options provided are:
1. Cell wall
2. Plastids
3. Central vacuole
4. Centrioles

### Step 2: Evaluate each option
- **Option 1: Cell wall**
- The cell wall is a rigid outer layer found in plant cells. It provides structure and protection. Animal cells do not have a cell wall; they only have a cell membrane.
- **Conclusion**: This option is incorrect because the cell wall is present in plant cells.

- **Option 2: Plastids**
- Plastids, such as chloroplasts, are organelles involved in photosynthesis and are found only in plant cells. They are responsible for the green color of plants.
- **Conclusion**: This option is incorrect because plastids are present only in plant cells.

- **Option 3: Central vacuole**
- The central vacuole is a large vacuole found in plant cells that stores nutrients and waste products and helps maintain turgor pressure. While animal cells have vacuoles, they are typically smaller and not as prominent as the central vacuole in plant cells.
- **Conclusion**: This option is incorrect because the central vacuole is present in plant cells.

- **Option 4: Centrioles**
- Centrioles are cylindrical structures found in animal cells that play a crucial role in cell division. They are not found in plant cells.
- **Conclusion**: This option is correct because centrioles are present in animal cells but absent in plant cells.

### Final Answer
The cell organelle that is not present in plant cells but is present in animal cells is **centrioles**.
