 Needle-Leaf Conifers  Scale-Leaf Conifers  Untoothed Simple leaves  Toothed Simple Leaves  Lobed Simple Leaves  Compound leaves

 Conifer- grow cones  Deciduous- drop leaves during winter  Evergreen- stay green all year Which of these two are opposites???

Hardwood that it grows flowers, like the cherry blossom tree. Hardwood trees have broad leaves and are usually deciduous. Its seeds have some kind of covering - an apple tree hides its seeds in an apple, and an oak tree hides its seeds in an acorn.

 Softwood means it is coniferous.  Instead of growing flowers, it grows cones, like the pine tree!  And instead of broad leaves, it usually grows needles on its branches. Its seeds have no covering, and just fall to the ground to grow a new tree.

 The terms "softwood" and "hardwood" aren't complete nonsense though – softwoods tend have softer wood than hardwoods, but it just isn't always true.

 Needlelike  Scalelike

 Unique in that the leaves are narrow in width and quite long in length.  Needle length differs among tree species  Helps with Tree Identification

Single- 1 needle per node Group- 2-5 needles per node Cluster- 5 or more needles per node

 Flat  Four-Angled  Three Angled Fir Spruce

 Cedar  Cypresses  Junipers  The shape consists of overlapping leaves which look like scales
