Flowers are the organs of reproduction only in higher plants. The key difference between Cryptogams and Phanerogams is that cryptogams are non-seed bearing primitive lower plants while phanerogams are seed bearing higher plants. They are unicellular. For instance, male cones have male gametophytes (pollen), and they are smaller than cones with female gametophytes.
