7、ited Savannah for a weekend and fell in love with_.15.TreesTo many, the word trees evokes images of such ancient, powerful, and majestic structures as the redwood and the giant sequoia (红杉), among the most massive and longest living organisms in the world. Although the majority of the Earths biomass
8、 is represented by trees, the fundamental importance of these seemingly ubiquitous plants for the very existence and diversity of life on Earth is perhaps not fully appreciated. Our very biosphere is dependent on the metabolism, death, and recycling of plants, especially trees. Their vast trunks and
9、 root systems store carbon dioxide and water and respire oxygen into the atmosphere. The organic matter of the soil develops primarily from plant residues (that is, from decayed leaves, twigs, branches, roots, and fallen trees), which release important nutrients, such as nitrogen, carbon, and oxygen
10、.The tree is not an immutable biological category but rather a human concept based on visual criteria. Perhaps a general definition would describe a tree as a perennial(多年生的) woody plant that develops along a single main trunk to a height of at least 4.5 metres at maturity. This may be contrasted wi
11、th a shrub, which might be loosely defined as a woody plant with multiple stems; in most cases, a shrub is less than 3 metres tall. However, a species fitting the description of either in one area of the world might not necessarily do so in other regions, since a variety of stresses shape the habit
12、of the mature plant. Thus, a given woody species may be a tree in one set of habitats within its range and a shrub elsewhere. 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 mountain-top, the variation due principally to stress
13、es exerted by such environmental conditions as altitude, temperature, and oxygen tension.In the early stages of the development of terrestrial life, land plants were rootless and leafless, since they had their origins in aqueous environments, they did not require the specialized conducting and suppo
14、rting 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. Habitats farther from the water as well as aerial habitats represented available uninhabited enviro
15、nments.One key to exploiting these habitats is large size. This, however, requires physiological and morphological (形态的) complexity. If all the tissues of massive tree trucks were alive, for example, the physiological cost of maintaining these structures in the living state would be enormous, and probably unattainable. The elegant solution came in the form. of tremendous structural adaptations, new tissues and organs permitted localization of the functions of the plant body.The evolution of vascular tissues and localized regions of cell division p
