2 ClassificationClassify: scientists organize, or classify, things by putting them in groups based on similar properties or behaviors.Classification helps scientists think about concepts or efficiently.
3 How Leaves Are Classified Classified by the basic pattern on veinsThere are 3 patterns to help classify leaves:PalmatePinnateParallel
4 Palmate LeafSeveral veins extending from the place where the leaf stem attaches to the leaf.
5 Pinnate LeafPinnate Leaf: One large vein extending the length of the leaf with smaller veins branching off.Pinna means feather, so pinnate leaf resembles a feather.
6 Parallel LeafParallel: Many small veins running the length of the leaf.Long, narrow leaves, like blades of grass, tend to have parallel veins.
7 Other Ways to Classify Leaves Leaf shape (blade)Kind of edge (margin) on the leafKind of attachment to the stem (petiole)Venation: Palmate, pinnate, and parallel
