The cell wall in onion peel cell is made of

Options

A. starch
B. gelatin
C. cellulose
D. cell sap

Answer

### Step-by-Step Solution:

1. **Understanding Onion Peel Cells**:
- Onion peel cells are plant cells. Unlike animal cells, plant cells have a rigid structure called the cell wall.

2. **Identifying Components of the Cell Wall**:
- The question asks about the composition of the cell wall in onion peel cells. The options provided are gelatin, starch, and cellulose.

3. **Analyzing Each Option**:
- **Starch**:
- Starch is a carbohydrate that serves as food storage in plants. It is made up of glucose units. However, starch is not a structural component of the cell wall.
- **Gelatin**:
- Gelatin is a protein derived from animal collagen and is not found in plant cells. It is used in food and cosmetics but does not contribute to the cell wall structure.
- **Cellulose**:
- Cellulose is a complex carbohydrate that forms the primary structural component of the plant cell wall. It provides rigidity and strength to the cell wall.

4. **Conclusion**:
- After analyzing the options, it is clear that the cell wall in onion peel cells is made up of cellulose.

### Final Answer:
The cell wall in onion peel cells is made of **cellulose**.
