Bryophytes
Group of non-vascular, seedless land plants that lack true roots, stems, and leaves; produce eggs in archegonia, and produces flagellated sperm in antheridia
Reproduction
Eggs in archegonia, sperm in antheridia, and sperm swim to egg in film of water
Common Shared Traits
Each form monophyletic phylum, share common structural/reproductive/ecological features, models of early terrestrial plants, and gametophyte is dom gen
Hornworts
Have small sporophytes that carry on photosynthesis and resemble tiny green broomhandles (closest to vascular plants)
Liverworts
First to evolve and have either a flattened thallus or leafy appearance
Antheridia
Haploid, sac-like organs that produce and release flagellated sperm for fertilization
Mosses
Leafy shoot, can produce asexually (fragmentation), dependent sporophyte consists of foot/stalk/sporangium, and store water
Climate Effect
Store CO2 - cold - grow slow and absorbing less CO2→ Atmospheric CO2 rises→ Climate is warmed
