Q: Is wood a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants? ¶
Q: Are woods not necessarily hard? ¶
A: Yes, and softwoods are not necessarily soft.
Q: Is wood called "fat lighter"? ¶
A: Yes, Structures built of fat lighter are almost impervious to rot and termites; however they are very flammable.
Q: Is wood often called "second-growth"? ¶
A: Yes, because the growth of the young timber in open stands after the old trees have been removed is more rapid than in trees in a closed forest, and in the manufacture of articles where strength is an important consideration such "second-growth" hardwood material is preferred.
Q: Is wood reduced so that very slow growth produces comparatively light? ¶
A: Yes, and porous wood composed of thin-walled vessels and wood parenchyma.
Q: Is wood often visually distinct from the living sapwood? ¶
A: Yes, and can be distinguished in a cross-section where the boundary will tend to follow the growth rings.
Q: Is wood very uniform in texture and is easy to work? ¶
Q: Is wood gradual? ¶
A: Yes, while in the narrow rings the spring wood passes into summer wood abruptly.
Q: Is wood no indication of strength? ¶
Q: Was wood consumed for this purpose in 1991? ¶
Q: Is wood harvested? ¶
Q: Is wood reflected in the composition of the constituent lignin? ¶
Q: Is wood alder? ¶
A: Yes, and basswood, birch, buckeye, maple, willow, and the Populus species such as aspen, cottonwood and poplar.
Q: Is wood somewhat more fragile? ¶
Q: Is wood a heterogeneous? ¶
A: Yes, and hygroscopic, cellular and anisotropic material.
Q: Is wood painted? ¶
A: Yes, such as skirting boards, fascia boards, door frames and furniture, resins present in the timber may continue to 'bleed' through to the surface of a knot for months or even years after manufacture and show as a yellow or brownish stain.
Q: Is wood much reduced both in quantity and quality? ¶
Q: Are woods black ironwood? ¶
Q: Are woods mostly the result of injury by birds? ¶
Q: Is wood relatively thicker in the upper portion of the trunk of a tree than near the base? ¶
A: Yes, because the age and the diameter of the upper sections are less.
Q: Is wood very roughly proportional to the size of the crown of the tree? ¶
Q: Is wood preferred over softwood because it creates less smoke and burns longer? ¶
Q: Is wood hydroscopic this potential instability effectively limits the length and width of the boards? ¶
Q: Is wood also commonly used as shuttering material to form the mold into which concrete is poured during reinforced concrete construction? ¶
Q: Is wood sometimes defined as only the secondary xylem in the stems of trees? ¶
A: Yes, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs.
Q: Are woods used: solid wood doors are often made from poplar? ¶
A: Yes, and small-knotted pine, and Douglas fir.
Q: Is wood seen to be very thick-walled and with very small cell cavities? ¶
A: Yes, while those formed first in the season have thin walls and large cell cavities.
Q: Is wood very dense and is deep-colored? ¶
A: Yes, and presenting a very decided contrast to the soft, straw-colored earlywood.
Q: Is wood the palms? ¶
Q: Are woods more complex? ¶
Q: Is wood characteristic of such species as chestnut? ¶
A: Yes, and black locust, mulberry, osage-orange, and sassafras, while in maple, ash, hickory, hackberry, beech, and pine, thick sapwood is the rule.
Q: Is wood usually darker than that of the sapwood, and very frequently the contrast is conspicuous? ¶
A: Yes, This is produced by deposits in the heartwood of chemical substances, so that a dramatic color variation does not imply a significant difference in the mechanical properties of heartwood and sapwood, although there may be a marked biochemical difference between the two.
