One of these is not a function of the non-living layer of the cell

Options

A. gives shape to the cell
B. protects the cell from damage
C. synthesizes hormones
D. helps in cell to cell interaction

Answer

To solve the question regarding the functions of the non-living layer of the cell, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Non-Living Layer of the Cell**:
- The non-living layer of the cell is known as the **cell wall**. It is a rigid structure that surrounds the plasma membrane in plant cells and fungal cells.

2. **List the Functions of the Cell Wall**:
- The cell wall has several key functions:
- **Gives Shape to the Cell**: It provides structural support and maintains the shape of the cell.
- **Protects the Cell from Damage**: It acts as a protective barrier against mechanical damage and pathogens.
- **Helps in Cell-to-Cell Interaction**: It facilitates communication and interaction between adjacent cells.
- **Prevents Entry of Undesirable Macromolecules**: It acts as a barrier to prevent harmful substances from entering the cell.

3. **Evaluate the Given Options**:
- The question presents four options:
1. Gives shape to the cell
2. Protects the cell from damage
3. Synthesizes hormones
4. Helps in cell-to-cell interaction
- From the functions listed, options 1, 2, and 4 are indeed functions of the cell wall.

4. **Identify the Incorrect Function**:
- The function that is **not** associated with the non-living layer (cell wall) is option 3: **Synthesizes hormones**. Hormone synthesis occurs within living cellular structures, not in the cell wall.

5. **Conclusion**:
- Therefore, the correct answer to the question is **option 3: Synthesizes hormones**.
