Question

Which of the following wood is involved in the conduction of water and minerals from root to leaf?​

Answer 1

Answer:

Question is not clear but I will try my best to answer it.

Explanation:

conduction of water and minerals occurs through xylem in plants.

Answer 2

The greater part of secondary xylem in old trees is dark brown due to deposition of organic compounds in the central or innermost layers of the stem. This region comprises dead elements with highly lignified walls and is called heartwood. It does not conduct water but gives mechanical support to the stem.

The peripheral part of the secondary xylem is lighter in colour and is known as the sapwood. The walls are not lignified and there is no deposition of organic compounds. It is involved in the conduction of water and minerals from root to leaf.
