Tree structure
structure of a treeThe tree is composed of an underground part, the roots, and two aboveground parts, the trunk and the crown.
bole: Part of the tree trunk extending between the stump and the first lower limbs; it has no offshoots.
limb: Offshoot growing directly out of a tree trunk, subsequently dividing into branches and twigs.
twig The most slender offshoot of a tree branch.
crown: Part of the tree above the trunk, including the branches and the foliage.
radicle: The most slender offshoot of a tree root.
shallow root: Root, often having many offshoots, growing somewhat horizontally into the rich moist topsoil.
taproot: First root growing out of the seed that grows vertically into the soil; it usually has few offshoots, its main function being to anchor the tree in the ground.
branch: Offshoot of one of the tree’s limbs.
top: Apex of the tree’s crown.
branches: The aggregate of larger and smaller branches that provide support for the tree’s leaves, flowers and fruit.
foliage: The aggregate of the leaves on a tree; it is especially adapted to capture light and perform photosynthesis.
root-hair zone:Part of the radicle covered in small absorbent hairs that ensure the tree is supplied with mineral salts and water.

Trunk
cross section of a trunk Moving from the center to the periphery there are six parts: the pith, the heartwood, the sapwood, the cambium, the phloem and the bark.
