Document Summary
Crown: food production (photosynthesis, water & temperature regulation, extends from the main bole and stems, consists of branches, twigs, leaves, and (transpiration) reproductive structure, it is where the tree increases each year in. Shoots (trunks, branches, stems) height and spread of branches. Foliage: refers to the collective leaves of the crown, produces the food for the tree. Bole (trunk: supports the crown, consists largely of dead biomass (older trees) They are arranged as a support structure: structure considered for lumber, food & water transport, structural support. Roots: nutrient & water uptake, anchorage & stability. Structural & environmental functions: anchorage, soil stability, contribution to soil carbon, structural support, habitat & food for ora & fauna, light interception, air quality. Water enters through the roots: travels through the system and exits the leaves. Sugars enter through the leaves (photosynthesis: it is interchangeable through roots, trunk, branches, stems, and leaves. Coarse roots: largely structural and for storage.
