Heartwood and Sapwood Consist Of

Question

Heartwood and sapwood consist of
A) bark.
B) periderm.
C) secondary xylem.
D) secondary phloem.
E) cork.

Accepted Answer

Heartwood and sapwood are both types of secondary xylem, which is the tissue responsible for transporting water and minerals from roots to leaves in woody plants. The distinction between heartwood and sapwood is based on their age and function; heartwood is older and no longer functioning in water transport, while sapwood is still actively transporting water. Neither bark, periderm, secondary phloem, nor cork are directly related to heartwood and sapwood.
