Which of the following is present in animal cell but absent in plant cell?

Options

A. Plastids
B. Large sap vacuole
C. Cell wall
D. Centriole

Answer

To solve the question "Which of the following is present in animal cell but absent in plant cell?", we can follow these steps:

### Step 1: Analyze the options
We need to look at the options provided and identify which structures are characteristic of animal cells and which are characteristic of plant cells.

### Step 2: Evaluate each option
1. **Plastids**: These are organelles found in plant cells, responsible for photosynthesis (like chloroplasts) and storage (like amyloplasts). They are absent in animal cells.
- **Conclusion**: This option can be eliminated.

2. **Large sap vacuole**: Plant cells typically have a large central vacuole that stores nutrients and waste products and helps maintain turgor pressure. In contrast, animal cells may have small vacuoles, but they do not have a large sap vacuole.
- **Conclusion**: This option can also be eliminated.

3. **Cell wall**: The cell wall is a rigid outer layer found in plant cells, providing structural support and protection. Animal cells do not have a cell wall; instead, they have a flexible plasma membrane.
- **Conclusion**: This option can be eliminated as well.

4. **Centriole**: Centrioles are cylindrical structures found in animal cells that play a crucial role in cell division by helping in the formation of spindle fibers. Plant cells do not have centrioles.
- **Conclusion**: This is the correct option as it is present in animal cells but absent in plant cells.

### Final Answer
The structure that is present in animal cells but absent in plant cells is **Centriole**.
