Life cycle of fern

  1. 1. Life Cycle of Fern<br />By: Alyssa Denise R.Vicera<br />
  2. 2. Word Box<br />Give the definition of the following words:<br />Fertilization<br />Zygote<br />Meiosis<br />Embryo<br />Mitosis<br />
  3. 3. Alternation of Generations<br />It is also known as alternation of phases or metagenesis. This is the cycle of reproduction in which a haploid gametophyte alternates with a diploid sporophyte.<br />
  4. 4. Words To Remember<br />
  5. 5. Sorus<br />It is the cluster of sporangia.<br />
  6. 6. Sporangium/Sporangia<br /> It is an enclosure in <br />which spores are formed.<br />
  7. 7. Gametophyte (Prothallus)<br />It is the haploid, multicellular phase of plants and algae that undergo<br />alternation of generations, with each of its cells containing <br />only a single set of <br />chromosomes.<br />
  8. 8. Sporophyte<br />It is the diploid form of plants that have alternation of generations. It develops from a zygote and produces asexual spores.<br />
  9. 9. Rhizoids<br />These are thread-like growths from the base or bottom of a plant, <br />found mainly in lower <br />groups such as algae, <br />fungi, bryophytes and <br />pteridophytes, that <br />functions like roots <br />of higher plants.<br />
  10. 10. Antheridium<br />It is a haploid structure or organ producing and containing male gametes called sperm.<br />
  11. 11. Archegonium<br />It is a multicellular structure or organ of the gametophyte phase of certain plants, producing and containing the ovum or female gamete.<br />
  12. 12. The Life Cycle<br />
