Vedclass · Answer

(D) The $Heartwood$ (duramen) is the central,darker part of the secondary xylem that is no longer involved in water conduction. It is characterized by the deposition of organic compounds like tannins,resins,oils,gums,aromatic substances,and essential oils in the vessels and tracheids. These substances make the $Heartwood$ hard,durable,and resistant to the attacks of microorganisms and insects. Because the vessels are blocked by these deposits (often forming $Tyloses$),the $Heartwood$ consists of dead and non-conducting elements,whereas the $Sapwood$ (alburnum) is the peripheral,lighter-colored region that remains active in water conduction.

The $Heartwood$ is different from $Sapwood$ due to the presence of:
