a.) Sapwood
The 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. Heartwood
Heartwood 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.

∙ 9y agoHardwood trees are trees with seeds with some sort of covering, like fruit or hard shell. Softwoods, on the other hand, like pine trees, are gymnosperms, dropping seeds with no extra coverings at all. The term has almost nothing to do with the density of the wood in the tree.

As sapwood ages it dies and becomes?
as sapwood dies it becomes all mossy and sticky
Name a type of cell or tissue found in a tree bark.?
It is Heartwood. (The Older xylem cells of heartwood no longer carry water).
Is heartwood made of dead xylem tissue?
Yes
Where are xylem cells that no longer conduct water found?
Heartwood
Can the heartwood of a plant be removed without the plant dying?
It is almost impossible
What is heartwood surrounded by?
sapwood
In a woody dicot stem the xylem is divided into?
Sapwood and Heartwood.
How to tell the difference between a white and pink dogwood if there are no blooms?
You can determine the color through its sapwood and heartwood. Narrow heartwood is a reddish one. Wide sapwood is cream to pale in color.Ê
What is heartwood features?
lighter colour and lot wetter
What trees produce both hardwoods and softwoods?
This one requires a bit of explanation. A hardwood tree has broad leaves--oaks, maples, birches. A softwood tree has needle leaves--pines and firs. Since no tree has both kinds of leaves, no tree can produce both hardwood and softwood. Now...every tree contains heartwood and sapwood. The sapwood is to the outside and carries the sap from the roots to the leaves. Heartwood is inside the sapwood, and it's more dense because it gives the tree its strength. So, heartwood is harder than sapwood, but it's relative; maple sapwood is very hard compared to poplar heartwood.
Is the core of a tree dead or alive?
The center of a tree trunk is dead. It's called the heartwood. It's made up of nonliving cells that were called sapwood when they were living and younger. So heartwood is the older, dead version of the younger, living sapwood of a tree trunk.
What does heartwood do?
Heartwood is the most inner part of a tree. It is the most inner part because it keeps the tree alive. It is surrounded by 4 more layers of the trunk- the outer bark, inner bark, cambium, and sapwood.
What covering of tree?
From outside to inside, the botanical basics of a tree are Outer Bark, Inner Bark, Cambium, Sapwood, and Heartwood.
What is the term for the soft part that finally becomes the core of a tree?
Sapwood is the term for the soft part that finally becomes the core of a tree.Specifically, sapwood can be found between the cambium cell layer and the heartwood. It functions to transport water into the tree's foliage. It is made up of layers of newer and older wood. The older wood will harden into heartwood as newer layers are added. It therefore will turn into the core of a tree over time and with age.
The growing part of a tree which builds a new layer of bark on the outside and wood on the inside?
My science book describes as sapwood being the living outer portion of the tree, while heartwood is the inner.
What is timber defects like shake checking wane and split?
Checking is a natural occurrence in lumber and poles that happens when the sapwood of a tree dries around the heartwood. Usually, it does not have an affect in the structural value.
What is function of the heartwood?
That it aromatizes and darkens wood, remains mechanically strong and resists decay and wood-preservative chemicals describes the function of heartwood in a woody plant. Heartwood also goes by the name duramen, from the same-spelled Latin word for "hardness." It represents the dead central wood, as opposed to the outer living layers, known as alburnum and sapwood, for mineral and water transport.
