Plants and Fungi

             Plants experience a multicellular haploid stage and a multicellular diploid stage, which makes them a haplodiplontic species. The.
             progression from haploid to diploid is called alteration of generations. Zygomycetes (Fungi phyla Zygomycota) are entirely haploid, excepting .
             only the diploid zygote. The diploid stage of plants is the sporophyte. In the sporangia, the sporophyte produces four haploid spores by .
             meiosis. These spores divide by mitosis, producing a mulitcellular haploid gametophyte. The gametophyte is the source of gametes, which will.
             fuse to produce a zygote. Zygomycetes experience a fusion of gametangia where + and - strains must be present in order for nuclei to grow .
             together and produce diploid zygote nuclei. Mitosis does not occur in the zygomycete reproductive cycle. Distinct to the phylum zygomycota, is .
             the formation of a temporary reproductive structure called the zygosporangium. In plants, meiosis occurs inside sporangia that are permanent .
             structures, and then continue on to divide by mitosis. Both kingdoms produce diploid zygotes, but plants' zygotes produce a diploid sporophyte,.
             and zygomycetes produce haploid hyphae.
             2. Fungi have traditionally been included in the plant kingdom, but there are enough significant differences between the two, to distinguish fungi.
             as a separate kingdom. One of the main differences is the fact that fungi are heterotrophs. They obtain their food by external digestion. Fungi.
             contain no chlorophyll, and therefore cannot photosynthesize. Plants are autotrophs, and can carry out photosynthesis to produce their own .
             food. Body structure is another chief difference between fungi and plants. Plants are multicellular with specialized cells that form tissues and .
             organs. Fungi have filamentous body structures with long slender filaments called hyphae. The hyphae are joined together by cross walls called.
             septa. A third difference is their reproductive modes.
