The wall of cork cell is mostly impregnated with

Options

A. Cellulose
B. Suberin
C. Cutin
D. Lignin

Explanation

### Step-by-Step Solution:

1. **Understanding Cork Cells**: Cork cells are specialized plant cells that are primarily found in the outer bark of trees. They serve as protective layers for the plant.

2. **Composition of Cork Cell Walls**: The walls of cork cells are made up of various substances. The main components include cellulose, suberin, cutin, and lignin.

3. **Identifying the Key Component**: Among these components, suberin is the most significant for cork cells. It is a waxy substance that is deposited in the cell walls as the cells mature.

4. **Function of Suberin**: Suberin makes the cork cell walls impermeable to water, which is crucial for protecting the plant from water loss and pathogens.

5. **Conclusion**: Therefore, the wall of cork cells is mostly impregnated with suberin.

### Final Answer:
The wall of cork cell is mostly impregnated with **suberin**.
