Biology Lesson 5.3

  1. 1. Lesson 5.3Ferns
  2. 2. Characteristics of FernsVascularNon floweringSpore producing, no seedsSpores found in sori on the back of the leaf
  3. 3. Characteristics of FernsVascularNon floweringSpore producing, no seedsSpores found in sori on the back of the leafSpores are produced by sporangialocated in the sori
  4. 4. Characteristics of FernsVascularNon floweringSpore producing, no seedsSpores found in sori on the back of the leafSpores are produced by sporangi located in the soriSpore - A small, single-celledreproductive body that is highlyresistant to dry and heat and iscapable of growing into a neworganism.
  5. 5. Characteristics of FernsVascularNon floweringSpore producing, no seedsSpores found in sori on the back of the leafSpores are produced by sporangi located in the soriHave rhizomes orstems that growhorizontallyUnderground petioleAsexual reprod.
  6. 6. Characteristics of FernsVascularNon floweringSpore producing, no seedsSpores found in sori on the back of the leafSpores are produced by sporangi located in the soriHave rhizomes or stems that grow horizontally undergroundFronds = mature leaves of afernFiddle heads = rolled upimmature leaves of a fern
  7. 7. FiddleheadFrond
  8. 8. Life Cycle of a FernHas alternating generationsor two generations. A. Sporophyte generation • What normally think of as a fern • Produces spores • Last 3 – 7 years
  9. 9. Life Cycle of a Fern
  10. 10. Life Cycle of a FernHas alternating generations or two generations.A. Sporophyte generationB. Gametophyte generation Spore develops into prothallum (heart shaped structure)
  11. 11. Life Cycle of a FernHas alternating generations or two generations.A. Sporophyte generationB. Gametophyte generationProthallum makes the female gamete(egg) in the archegonium and the malegamete (sperm) in the antheridiumGametes are released andfertilization occurs forms sporophytes Last 3 – 7 weeks
  12. 12. sporophyteGametophyte
  13. 13. Other spore producing plants include:Club mosses and horsetails
