Identify the wrong statement in context of heartwood

Options

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

Answer

To identify the wrong statement in the context of heartwood, let's analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Heartwood**:
- Heartwood, also known as duramen, is the innermost part of a tree trunk. It is formed during the secondary growth of dicotyledonous plants.
- It consists mainly of dead cells that provide structural support to the tree.

2. **Analyzing the Options**:
- **Option 1**: "Organic compounds are deposited in it."
- This statement is **true**. Heartwood contains various organic compounds, including resins and tannins, which are deposited in the wood.

- **Option 2**: "It is highly durable."
- This statement is **true**. Heartwood is known for its durability and resistance to decay due to the presence of these organic compounds.

- **Option 3**: "It conducts water and mineral efficiently."
- This statement is **false**. Heartwood consists of dead cells and does not conduct water and minerals efficiently. The conduction of water and minerals primarily occurs in the living xylem (sapwood), not in heartwood.

- **Option 4**: "It comprises dead elements with highly lignified walls."
- This statement is **true**. Heartwood is made up of dead cells that have highly lignified walls, providing strength and support.

3. **Conclusion**:
- The wrong statement in the context of heartwood is **Option 3**, as heartwood does not conduct water and minerals efficiently due to the presence of dead elements.

### Final Answer:
The wrong statement in the context of heartwood is **Option 3: "It conducts water and mineral efficiently."**
