In ferns, if the rhizome is radially symmetrical, compact and short then it is referred to as rootstock. It is a diploid cell. Spores are produced from sporangia by meiosis so they are also haploid. The sporophyte is diploid and the gametophyte is haploid. Sporangia form on the underside of the gametophyte.
