All plants produce spores by meiosis; algae and fungi produce spores by meiosis or mitosis. This is called alternation of generation. In the lower plants, the gametophyte generation is the dominant stage; in higher plants, the sporophyte generation is the dominant stage. Four major groups of plants have evolved. The bryophytes are seedless and disperse via haploid spores. The ferns, gymnosperms, and flowering plants have vascular tissue.
In angiosperms, meiosis in the sporophyte generation produces two kinds of spores. 1  microspores. 2  which develop in the microsporangium and. 3  which will germinate and develop into the male gametophyte generation and.4  megaspores. Dioecious plants have imperfect flowers on separate plants; that is, some plants are male, some female. 2  Examples include willows, poplars, and the date palm. 3  Most dioecious plants use an X-Y system of of sex determination like that in mammals [ Link ].
