The evolution of discrete plant body parts with separate functions allowed plants to move onto the land and undergo an incredible adaptive radiation. These graceful trees, which are natives of humid montane forests in the tropics and subtropics and of warm temperate regions of the Southern Hemisphere, have huge lacy leaves; they are the remnants of a vastly more numerous flora that populated much of the Earth during the Carboniferous Period (about 360 to 300 million years ago).

Parent − Any node except the root node has one edge upward to a node called parent. Elements of trees are called their nodes. Popular classifications, however, remain useful tools for studying the common stresses that the environment exerts on all plants and the general patterns of adaptation that are shown no matter how distantly plants are related. On an ecological basis, however, the tree can be recognized as a natural construct, as it represents an adaptive strategy by many different taxa to exploit and dominate the habitat above the ground. This article discusses the historical, popular, and botanical classifications of trees, their evolution, their importance to humans, and their general structure and patterns of growth. Dendrochronology or tree-ring dating has been available as a recognized scientific technique since the early 1900s.

One circumstance where a wound dressing may help is in regions where oak wilt is a serious problem. Roots provided anchorage and absorption of sufficient water and nutrients to support the remainder of the plant. For example, the spruce and fir may thrive in the tree form at the base of a mountain but assume a shrub form near the mountaintop, the variation due principally to stresses exerted by such environmental conditions as altitude, temperature, and oxygen tension. Getting your new tree off to a healthy start will help the tree mature to its full size and ensures it will provide environmental, economic, and social benefits throughout its lifetime.

Since they had their origins in aqueous environments, they did not require the specialized conducting and supporting tissues afforded by roots and stems, nor did they require localized regions of carbohydrate synthesis, since each cell was involved in metabolism, water and nutrient absorption, and respiration. The finished diagram bears a resemblance to a tree, with a trunk and multiple branches. A decision tree is a flowchart-like diagram that shows the various outcomes from a series of decisions. Modern classifications of plants attempt to assign a plant to a particular taxon and establish relationships with other plants based on genetics, cytology, ecology, behaviour, and probable evolutionary lineages, in addition to gross morphology.
