The presence of lignin in a cell is a characteristic of
(a) Phloem
(b) Woody tissue
(c) All soft tissues
(d) Cork

Options

A. Phloem
B. Woody tissue
C. All soft tissue
D. Cork

Answer

To solve the question regarding the presence of lignin in a cell, we need to analyze each option provided:

1. **Understanding Lignin**: Lignin is a complex organic polymer found in the cell walls of many plants, making them rigid and woody. It is primarily found in the secondary cell walls of certain plant cells.

2. **Evaluating the Options**:
- **(a) Phloem**: Phloem is responsible for the transport of nutrients and does not typically contain lignin. It is mainly composed of living cells that facilitate the movement of sugars and other organic compounds.
- **(b) Woody tissue**: Woody tissues, such as those found in trees and shrubs, are characterized by the presence of lignin in their cell walls, particularly in the xylem. This lignin provides structural support and rigidity.
- **(c) All soft tissues**: Soft tissues in plants, such as parenchyma, do not contain lignin. They are primarily involved in storage and metabolic functions and are not lignified.
- **(d) Cork**: Cork is a protective tissue that forms the outer layer of stems and roots. While it does have some structural components, it does not contain lignin.

3. **Conclusion**: Based on the analysis, the presence of lignin in a cell is characteristic of **(b) Woody tissue**.

### Final Answer:
The presence of lignin in a cell is a characteristic of **(b) Woody tissue**.
