What is the difference between frond and cone

  Cones are also called Strobili. In plant anatomy, it’s the mass of bracts and scales that usually have an oval outline. They contain the reproductive organs of those non-flowering plants. Cones are the usual feature of certain pines and conifers, club mosses, gymnosperms, and horsetails.   Fronds, on the other hand, are a big divided leaf. The leaves of ferns can also be referred to as fronds, but it’s particularly a term for big leaves.
