A deposition material of secondary origin found in sclerenchyma cell is :

Options

A. Suberin
B. Pectin
C. Lignin
D. Hemicellulose

Answer

To answer the question regarding the deposition material of secondary origin found in sclerenchyma cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Sclerenchyma Cells**:
- Sclerenchyma is a type of permanent tissue in plants.
- It is characterized by its cells being dead at maturity and having thickened cell walls.

2. **Identify the Composition of Sclerenchyma**:
- The primary materials that can be deposited in the cell walls of sclerenchyma include substances like suberin, pectin, lignin, and hemicellulose.

3. **Focus on Secondary Deposits**:
- The question specifically asks for a deposition material of secondary origin. This refers to materials that are deposited after the cell has matured.

4. **Determine the Key Material**:
- Among the listed materials, lignin is known to be a major component of the secondary cell wall in sclerenchyma cells. It is responsible for the rigidity and strength of the cell walls.

5. **Conclude the Answer**:
- Therefore, the deposition material of secondary origin found in sclerenchyma cells is **Lignin**.

### Final Answer:
The deposition material of secondary origin found in sclerenchyma cells is **Lignin**.
