TREE ANATOMY
TREE CUT-AWAY
WARPS IN LUMBER
PHOTOSYNTHESIS
A reaction of organic compounds from carbon dioxide and water.
Light is absorbed by chlorophyll, the green pigment present in leaves.
This creates energy for the tree. The by-product off this reaction is
oxygen.
DIVISIONS OF TREES
Coniferous Trees
Softwood Bears needles Evergreens Bears cones to
reproduce
Deciduous Trees
Hardwood Bears leaves Lose their leaves
in winter Bears fruits and
nuts to reproduce

HARDWOOD PLYWOOD VS. SOLID HARDWOOD
PRO’S
Does not warp like solid lumber will.
Cut the size you want. No need to glue up panels.
Cheaper than solid woods.
Uses less trees to make hardwood plywood, than using solid lumber.
CON’S
Have to glue solid lumber on the end grain to hide the core of the plywood.
Exceptable to dents and scratches, exposing the core of the plywood.
Appearance not as nice as solid lumber.
