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.
Spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes.y contrast, gametes are units of sexual reproduction. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle but are resistant structures used for survival under unfavourable conditions.
