Although Algae show both isomorphic and heteromorphic life cycle but pteridophytes are exclusively heteromorphic. Alternation of generation” term employed by Hofmeister in 1851. He observed that in mosses and ferns there are two types of morphologically distinct individuals present in the life cycle. Both alternate during a life cycle back to back.
