• secondary
  • By the end of the first week, the rich nutrients and ease of attachment into the biofilm allow secondary colonizers of spores of macroalgae (e.g. enteromorpha intestinalis, ulothrix) and protozoans (e.g. vorticella, Zoothamnium sp. (wikipedia.org)
  • resistant
  • The disposal of any wastewater containing animal waste upstream of a drinking water intake can pose serious health problems to those drinking the water because of the highly resistant spores present in many animals that are capable of causing disabling disease in humans. (wikipedia.org)
  • form
  • The spores of seed plants, however, 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. (wikipedia.org)
  • In common parlance, the difference between a "spore" and a "gamete" (both together called gonites) 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. (wikipedia.org)
  • plants
  • Such plants typically give rise each kind of spores from within a separate sporangium, either a megasporangium that produces megaspores or a microsporangium that produces microspores. (wikipedia.org)
