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.
The male and female sex organs may be formed in compact structures on short stem axes called cones or strobili or on specialized leaves or in flowers. In gymnosperms, the sexes are separate, so both male and female sporangia are produced either on the same plant (monoecism) or on separate plants (dioecism).ymnosperms include all seed plants other than the angiosperms, or flowering plants. The absence of an enclosing structure is believed to be primitive, thus the first seed plants were gymnosperms.. The seeds of gymnosperms are borne exposed in open structures, such as cones or leaves.
