Pine Cones and Stems
Are pine cones part of the stem of a pine tree?
Pine cones are the flowering and fruiting structures on pine
trees, and they eventually fall off of the stems so technically
they are separate from the stems.
Anthony Brach Ph.D.
Pine cones are made of similar material as the stem, but pine cones are
different . The material and the pine cone shape protect the pine nuts
so they can germinate and grow into new trees.
