Similarities and Differences between Bryophytes and Vascular Plants and other things

The flashcards below were created by user DesLee26 on FreezingBlue Flashcards.

  1. Location


    mostly terrestrial

    all multicellular

    all develop from embryos within the female gametangium
  2. Vascular tissue

    Bryophytes: no vascular tissue, except for simple water-conducting cells or sugar-transporting cells in some mosses

    Vascular Plants: xylem and phloem present

    Bryophtes: no roots; have rhizoids (mostly parenchyma tissue) as anchoring and absorbing structures); no true stems and leaves

    Vascular Plants: true roots; stems and leaves
  3. Dominance of generation

    Spore Walls

    Gametangia and Sporangia
    Bryophytes: gametophyte dominant; sporophyte dependent on the gametophyte

    Vascular: sporophyte dominant; ultimately independent of the gametophyte

    Both spore walls contain sporollenin

    Both have gametangia and sporangia that are multicellular and protected by a jacket of sterile cells
  4. Explain the antheridium of a bryophyte.
    all cells to the inside of the sterile outer layer of cells are capable of producing sperm

    sterile cells cannot
  5. Explain the archegonium of the bryophytes.
    has a neck and a sterile layer of cells

    The venter is below the neck 

    the whole structure produces just one egg
  6. What does the sporangial head contain?


  7. Sphanum: Phylum __

    Portion of a "Leaf": What are the parts?

    • hyaline cell
    • vegetative cell
    • chloroplast
  8. Explain the life cycle (asexual) of Marchantia, a Liverwort
    gametophyte has gemmae cups which contain and produce gemmae which develop into the gametophyte
  9. Sexual Life cycle of Marchantia
    Gametophyte--> a and b

    a: female thallus with archegoniophores forms--> archegonium which produces one egg

    b: male thallus with antheridiophores forms--> antheridium--> produces sperm

    egg and sperm fuse--> fertilization (2n)--> zygote--> meiosis--> sporophyte--> spore release--> spores--> gametophyte
  10. Where is the antheridia located in Marchantia? archegonia?
    • antheridia: top part as scallops
    • archegonia are located downward up top
  11. What does an archegonium consist of?
    • neck
    • venter
    • egg
  12. What does a sporophyte consist of? in Liverwort
    • sporangium (2n jacket)
    • elaters (2n)
    • seta 2n 
    • foot 2n
