All seed plants have heterosporous spore production. Heterospory is the condition of species where they have two types of sporophylls: megasporophylls and microsporophylls. Megasporophylls produce megaspores that develop into female gametophytes while microsporophylls produce microspores that develop into male gametophytes.
