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 sporophyte. Once conditions are favorable, the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which will eventually go on to produce gametes. Two gametes fuse to create a new sporophyte.t is useful to contrast spores with gametes: spores are the units of asexual reproduction as a single spore develops into a new organism; gametes are the units of sexual reproduction as two gametes need to fuse to create a new organism.
