Identify the wrong statement in context of heartwood

Options

A. Organic compounds are deposited it
B. It is highly durable
C. It conducts water and minerals efficiently
D. It comprises dead elements with highly lignified walls

Answer

### Step-by-Step Solution:

1. **Understanding Heartwood**: Heartwood, also known as duramen, is the central part of a tree trunk. It is formed from the older xylem and is typically darker and denser than the surrounding sapwood.

2. **Analyzing the Statements**:
- **Statement 1**: "Organic compounds are deposited in it."
- This statement is correct. Heartwood contains various organic compounds such as tannins, resins, and gums.

- **Statement 2**: "It is highly durable."
- This statement is also correct. The presence of organic compounds contributes to the durability of heartwood, making it resistant to decay and pests.

- **Statement 3**: "It conducts water and minerals efficiently."
- This statement is incorrect. Heartwood is composed of dead cells and does not conduct water and minerals efficiently. This function is primarily carried out by the living sapwood.

- **Statement 4**: "It comprises dead elements with highly lignified walls."
- This statement is correct. Heartwood consists of dead xylem cells that have highly lignified walls, providing structural support.

3. **Identifying the Wrong Statement**: Based on the analysis, the third statement is the only incorrect one, as heartwood does not efficiently conduct water and minerals.

4. **Conclusion**: The wrong statement in the context of heartwood is that it conducts water and minerals efficiently.
