• The asexual, non-motile haploid spores of a fungus, which are named after the Greek word for dust (conia), are hence also known as conidiospores. (wikipedia.org)
  • In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte . (oxygenboules824.sbs)
  • Spores germinate to give rise to haploid gametophytes, while seeds germinate to give rise to diploid sporophytes. (oxygenboules824.sbs)
  • Vascular plant spores are always haploid . (oxygenboules824.sbs)
  • Spores are usually haploid and grow into mature haploid individuals through mitotic division of cells ( Urediniospores and Teliospores among rusts are dikaryotic). (oxygenboules824.sbs)
  • The haploid spores after release, germinate to produce amoeboid cells which develop into flagellate male and female gametes. (biologydiscussion.com)
  • Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. (oxygenboules824.sbs)
  • Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomycetes are now identified and classified based on morphological or physiological similarities to ascus-bearing taxa, and by phylogenetic analyses of DNA sequences. (wikipedia.org)
  • Asexual reproduction may occur through vegetative reproductive spores, the conidia. (wikipedia.org)
  • These fungi have evolved more complex asexual sporing structures, probably influenced by the cultural conditions of plant tissue as a substrate. (wikipedia.org)
  • In biology , a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. (oxygenboules824.sbs)
  • Fungi commonly produce spores during sexual and asexual reproduction. (oxygenboules824.sbs)
  • The diploid nuclei of the Plasmodium undergo reduction division before spore formation in the fruit-body. (biologydiscussion.com)
  • The portion of the Plasmodium which is not consumed for spore formation is converted into a net-like structure, known as capillitum. (biologydiscussion.com)
  • Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. (oxygenboules824.sbs)
  • The spores of seed plants are produced internally, and the megaspores (formed within the ovules) and the microspores are involved in the formation of more complex structures that form the dispersal units, the seeds and pollen grains. (oxygenboules824.sbs)
  • Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte , which eventually goes on to produce gametes. (oxygenboules824.sbs)
  • Plants that are homosporous produce spores of the same size and type. (oxygenboules824.sbs)
  • Such plants typically give rise to the two kind of spores from within separate sporangia, either a megasporangium that produces megaspores or a microsporangium that produces microspores. (oxygenboules824.sbs)
  • On liberation, a spore germinates through a pore in the wall and produces an amoeba which starts a vegetative phase and multiplies by binary fission. (biologydiscussion.com)
  • In common parlance, the difference between a "spore" and a " gamete " is that a spore will germinate and develop into a sporeling , while a gamete needs to combine with another gamete to form a zygote before developing further. (oxygenboules824.sbs)
  • The main difference between spores and seeds as dispersal units is that spores are unicellular, the first cell of a gametophyte, while seeds contain within them a developing embryo (the multicellular sporophyte of the next generation), produced by the fusion of the male gamete of the pollen tube with the female gamete formed by the megagametophyte within the ovule.
