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. A 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. Some angiosperms are imperfect, having either microsporangia or megasporangia but not both. 1  Monoecious plants have both types of imperfect flower on the same plant. 2  Dioecious plants have imperfect flowers on separate plants; that is, some plants are male, some female. 1 Dioecious plants have imperfect flowers on separate plants; that is, some plants are male, some female. 2  Examples include willows, poplars, and the date palm. 3  Most dioecious plants use an X-Y system of of sex determination like that in mammals [ Link ]. Spores are the reproductive cells for fungi and ferns. They are small and light weight so that they can easily be carried by the wind. In, a spore is a reproductive structure … that is adapted for dispersal and surviving for extended periods of time in unfavorable conditions. A chief difference between spores and seeds as is that spores have very little stored food resources compared with seeds. Angiosperms are  also called anthophytes or magnoliophytes.    The sporophyte is dominant and the gametophyte is the most reduced  of all plants. There are 300 000 so far named angiosperms.  Angiosperms evolved in the Cretaceous. Many have close-bound  mutualisms with pollinating insects. Gymnosperms (meaning naked seeds) are seed-bearing plants that don't produce flowers, instead they have male and female reproductive organs mostly in the form of cones. Thei … r microsporophylls release pollen into the air to make available to the ovule, in the megasporophylls causing fertilization. Alternation of generations is the term used to describe how spores  reproduce. This means, the spore is able to become a new plant or  organism from itself as a form of asex … ual reproduction. The spore  comes from the original plant or organism to become a new life  form. In angiosperms, meiosis in the sporophyte generation produces two kinds of spores. 1  microspores. 2  which develop in the microsporangium and. 3  which will germinate and develop into the male gametophyte generation and. 4  megaspores. 1 Dioecious plants have imperfect flowers on separate plants; that is, some plants are male, some female. 2  Examples include willows, poplars, and the date palm. 3  Most dioecious plants use an X-Y system of of sex determination like that in mammals [ Link ]. Ferns, mosses, liverworts and green algae are all plants that have spores. Spore plants have a different life cycle. A parent plant sends out tiny spores containing special sets of chromosomes. These spores do not contain an embryo or food stores.  They are seed plants. Bryophytes and ferns, on the other hand, reproduce by spores, and not by seeds. Seeds are different than spores in that the developing ovum, is encased in a protective seed along with a whole storage of nutrients should the seed have the opportunity to germinate.
