Options:
A) It comprises dead elements with highly lignified walls

Show Answer
Answer:
Correct Answer: D
Solution:
- Heartwood is the central, non-living part of a tree trunk, which does not conduct water and minerals. It is composed of dead cells with highly lignified walls, and organic compounds are often deposited in it, making it highly durable. The conduction of water and minerals is primarily the function of the sapwood, not the heartwood.
