Hardwoods: Woods come from broad-leaved trees in the botanical group angiosperms. Hardwoods are defined anatomically by the presence of vessels. Since hardwoods have vessels, they are also called porous woods. Vessels are the largest cells in hardwoods. Pores are the transverse openings of vessel elements. In the picture, several pores are circled.
Softwoods: Woods come from coniferous trees in the botanical group gymnosperms. Softwoods are defined anatomically by the absence of vessels. Since softwoods lack vessels, they are also called non-porous woods. In the picture, there are no vessels, but several resin canals are cicled. Resin canals can look much like vessels in hardwoods, but there are two easy ways to differentiate them. First, resin canals (if present) are usually found in the latewood, or in the area between the earlywood and the latewood. Vessels in hardwoods will be found in all portions of the growth ring. Second, there are far fewer resin canals in softwoods compared to the number of vessels in hardwoods.
