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 that make up the woody part of a tree. The heartwood is the inner, non-living part of the tree that no longer conducts water and nutrients, while the sapwood is the outer, living part of the tree that still conducts water and nutrients. Bark, periderm, secondary phloem, and cork are all different components of the outer protective layer of a tree, but they are not a part of heartwood or sapwood.
