General Characteristics/Evolutionary Traits of Nonvascular

  • Reproductive cells?

  • What do reproductive cells exhibit?

  • Which generation dominant?

  • Certain morphology differences?

  • Alternation of Generations

  • Spores - haploid unicellular structures that substitute sperm

  • Homospory

  • Gametophyte Dominant

  • No vascular tissue, roots, stems, or true leaves (Have microphylls)

  • -phyte/gia(ium)

  • Antheridio-

  • Archegonia-

  • -phore

Hepatophyta

How do reproduce?

Liverworts

  • Thalloid (flat leaf) or Leafy

Asexual:

  • Gemmae in Gemmae cups detach with water to form new plant

Sexual:

  • Antheridiophore- multiple antheridia containing sperm

  • Archegoniophore- multiple archegonia containing 1 egg each

Bryophyta

What does sporophyte consist of?

True Mosses (Bryophytes)

  • Antheridia- house sperm

  • Archegonia- house single egg

  • Rhizoids (fake roots)

Sporophyte:

  • Operculum (cap) covered by calyptra (shell)

  • Setra (stalk)

General Characteristics/Evolutionary Traits of Seedless Vascular

  • Which generation dominant

  • Morphology?

  • What do reproductive cells exhibit

  • Alternation of Generations

  • Sporophyte Dominant

  • Vascular tissue with megaphylls

  • Some exhibit heterospory with microspores (sperm) and megaspores (egg) or homospory

Lycophyta

Difference between 2 species?

Club Mosses, Quillworts, and Spike Mosses

Lycopodium (club moss)

  • Homosporous

  • Strobilus holds spores (cone shaped)

Selaginella (spike moss)

  • Heterosporous

Sphenophyta

Horsetails

  • Homosporous

  • Microphylls near brown sections

  • Have Pith - hollow center

  • Strobili that produce sporangiophores

New cards

Pterophyta

Ferns

  • Homosporous

  • Rhizomes with fronds (megaphylls)

  • Immature frond grow into spiral fiddleheads

  • Frond has pinnae (leaf) and pitiol (stem)

  • spores made in sori (brown spots under fronds/fern leaves)

  • Annulus catapults spores 

  • Some have indusium flap to protect sori
