2ClassificationClassify: scientists organize, or classify, things by putting them in groups based on similar properties or behaviors.Classification helps scientists think about concepts or efficiently.
3How Leaves Are Classified Classified by the basic pattern on veinsThere are 3 patterns to help classify leaves:PalmatePinnateParallel
4Palmate LeafSeveral veins extending from the place where the leaf stem attaches to the leaf.
5Pinnate 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.
6Parallel LeafParallel: Many small veins running the length of the leaf.Long, narrow leaves, like blades of grass, tend to have parallel veins.
7Other 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
