In sclerenchyma, wall is

Options

A. lignified
B. suberised
C. pectinised
D. cutinised

Answer

### Step-by-Step Solution:

1. **Understanding Sclerenchyma**:
- Sclerenchyma is a type of simple permanent tissue in plants. It is primarily composed of one type of cell.

2. **Composition of Sclerenchyma**:
- The cell wall of sclerenchyma is characterized by the presence of lignin, which is a complex organic polymer.

3. **Properties of the Cell Wall**:
- The walls of sclerenchyma cells are thick due to the high lignin content. This thickness contributes to the mechanical strength of the plant.

4. **Function of Lignin**:
- Lignin makes the cell wall waterproof, preventing water loss and helping to maintain moisture within the plant. It also aids in the transport of water.

5. **Mechanical Support**:
- The thick and lignified walls provide mechanical support to the plant, allowing it to withstand various stresses.

6. **Conclusion**:
- Therefore, in sclerenchyma, the wall is primarily lignified, making it thick and providing both waterproofing and mechanical support.

### Final Answer:
In sclerenchyma, the wall is lignified.
