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 produce naked seeds - a seed not enclosed in an ovary. Angiosperms produce covered seeds - a seed enclosed in an ovary. Angiosperms produce flowers and fruit. Many gymnosperms produce cones. None bear flowers or fruit. Male (left) and female (right) conifer cones. Gymnosperms are pollinated solely by wind.
