Explanation:

The life cycle of a gymnosperm involves alternation of generations, with a dominant sporophyte in which the female gametophyte resides, and reduced gametophytes. All gymnosperms are heterosporous. The male and female reproductive organs can form in cones or strobili.

Answer:

The life cycle of a gymnosperm involves alternation of generations, with a dominant sporophyte in which the female gametophyte resides, and reduced gametophytes. All gymnosperms are heterosporous. The male and female reproductive organs can form in cones or strobili.

It produces both male and female strobili. The cells of the strobili undergo meiosis, or cell division that reduces the number of chromosomes by half. This forms the gametophyte, the haploid stage. The male sex cells (pollen) then form, and fertilize the female sex cells (ovules).
