Lignin is most abundant in

Options

A. Collenchyma
B. Xylem
C. Phloem
D. Chlorenchyma

Answer

**Step-by-Step Solution:**

1. **Understanding Lignin**: Lignin is a complex organic polymer found in the cell walls of many plants, providing rigidity and resistance to decay.

2. **Analyzing the Options**:
- **Colon Chimera**: This structure primarily contains hemicellulose, pectin, and cellulose but lacks lignin. Therefore, it is not the correct answer.
- **Phloem**: The primary function of phloem is to transport sugars (like sucrose, glucose, and fructose) and other nutrients. It does not have a significant amount of lignin. Hence, this option is also incorrect.
- **Chlorine Chimera**: Similar to colon chimera, this structure does not contain lignin and is not the correct answer.
- **Xylem**: Xylem is responsible for the transport of water and minerals from the roots to other parts of the plant. It consists of dead, hollow cells that have lignified walls, making it strong and able to withstand pressure changes during water transport.

3. **Conclusion**: Based on the analysis, lignin is most abundant in **xylem**.

**Final Answer**: Lignin is most abundant in **xylem**.
