Roots: anchor the tree in the ground; absorb water and minerals from the soil
Trunk: strongest part of the tree providing the support for the rest of the tree; consists of 4 parts.
Outer Bark (cork): outer part of the trunk; is dead tissue, protects the living parts underneath.
Xylem: hollow cells that transport water and minerals from the roots throughout the tree, make up the wood of the tree.
Phloem: tissue that moves sap up and down a tree, makes up the inner bark or layer next to the outer bark; transports nutrients made in the trees leaves down to the roots. The tree will die if this layer is damaged.
Cambium: thin yellowish white layer found between the sapwood and inner bark which produces new xylem (wood) cells every year, allowing the tree to grow.
Heartwood: non-living core of the tree stem, giving the stem strength. Heartwood makes up most of the stem.
