Longitudinal section through a strobilus of a spike moss. The strobilus has 2 types of sporangia and is heterosporous. After meiosis in the microsporangia (haploid) microspores are formed that develop to male gametophytes, while the macrosporangia containing the (haploid) macrospores develop to the female gametophytes
