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.
Gymnosperms. Gymnosperms are one of the two groups of seed plants. The flowering plants (angiosperms), are the other. In going from mosses and ferns to the seed plants, we see a very significant difference in plant life cycles. In mosses and ferns the propagating units for new individuals are spores.In the seed plants, gymnosperms and angiosperms, the propagating units for new individuals are seeds.Spores are single, haploid cells, and develop into gametophytes. major distinction we can make between seed plants (gymnosperms and angiosperms) and the non-seed plants (mosses and ferns) is that seed plants are heterosporous and non-seed plants are homosporous.
