This section describes major tree parts and their variations. Leaves Shade Tolerance Some tree species are more efficient at making food (through photosynthesis) under low-light conditions. These are called shade tolerant. Examples include firs, lindens, hackberries, and redbuds. Shade intolerant species include cottonwoods, willows, aspens, birches, and pines. Shade tolerant trees may do well in full sun, but shade intolerant species always need plenty of light to do well. Shade intolerant species generally appear early in the life of a forest and grow quickly in height, while tolerant species appear later under the shade of the intolerant species.
Altered and becomes heartwood. Heartwood often is filled with dark colored substances that help it resist decay, though wood may also be darkened by mineral stains and injury. The wood on the outside of the stem, one to many rings wide, is called the sapwood. It is usually lighter in color than the heartwood and is responsible for water and mineral movement through the stem and for defense against injury. Rays Rays are ribbon-like groups of tracheids and parenchyma that move water and other substances in the xylem from the outer rings in or from the inner rings out.
