Question

Identify the correct statement in context of sapwood:

• A. Durable in damp locations.
• B. Comprises dead elements with highly lignified walls.
• C. It contains valuable extractable materials like tannin and dyes.
• D. It is highly efficient in conducting water and minerals.

Answer 1

The correct option is D It is highly efficient in conducting water and minerals.

Heartwood is found in the central core of a tree trunk. Sapwood is different from heartwood in being the outer light-colored portion of a tree trunk formed recently through which the water passes from the roots to the leaves. Hence, sapwood is highly efficient in conducting water and minerals.
Heartwood is more durable than sapwood in damp locations. Sapwood gives rise to heartwood in due course of time by the formation of tyloses, hence heartwood contains dead elements with highly lignified walls. The heartwood is dark due to their cell cavities infiltrated with various substances, which are the valuable extractable materials like tannins, dyes, resins and gums.
