Vedclass · Answer

(A) In older trees,the secondary xylem is differentiated into two regions: $Heartwood$ and $Sapwood$. $Heartwood$ is the central or inner part of the secondary xylem. It is dark in color due to the deposition of organic compounds like tannins,resins,oils,gums,aromatic substances,and essential oils in the central or innermost layers of the stem. These substances make it hard,durable,and resistant to the attacks of microorganisms and insects. It does not conduct water but provides mechanical support to the stem.
