Options
(a) presence of rays and fibres
(b) absence of vessels and parenchyma
(c) having dead and non -conducting elements
(d) being susceptible to pests and pathogens
Correct Answer:
having dead and non -conducting elements
Explanation:
Heartwood differs from sapwood in having dead and non-conducting elements. In old trees, the inner region that comprises dead elements with highly lignified walls is called heartwood. Heartwood does not conduct water but gives mechanical support to the stem. On the other hand, the peripheral region, which is lighter in colour are called sapwood. It is involved in the conduction of water and minerals from root to leaf
