Why sapwood is wetter softer then heartwood?

a.) SapwoodThe sapwood is the younger, softer outer portion of a tree that lies between the heartwood and the cambium (formative layer just under the bark) As comparatively new wood, sapwood is less durable and more permeable than heartwood.While a floor purely of sapwood may be beautiful and smoother than heartwood, the softness and permeability of the sapwood makes it expand and contract easily, which can cause it to warp in certain conditions. This weakness also manifests differently in various tree species; some have sapwood that is strong and durable, others have weak, soft sapwood that is not appropriate for wood floors. Many times, sapwood is graded higher than heartwood because it is smoother and less prone to knots and blemishes; the highest-grade sapwood is virtually free of any imperfections. Coloration of sapwood ranges from white to light and yellow blonde tones. HeartwoodHeartwood is the older, harder central portion of a tree. It usually contains deposits of various materials that frequently give it a darker color than sapwood. Denser and more durable than sapwood, heartwood is found primarily in aged trees.Heartwood is generally darker than sapwood, and doesn't have the same expansion and contraction problems that beset some sapwood. It makes a great wood floor because of its hardness and strength, and its resistance to many weather conditions. The hardness of heartwood, like sapwood, depends on the tree species and age of the tree.
