| | | | | | |
grasses, hardwoods, vascular, sporophyte dominant, seeds,
| | | | |
wind/animals(flowers) fertilization, wind animals (fruits) seeds dispersal
| | | | | | |

Marchantiophyta - ANSWER✔✔✔-liverworts | |
Bryophyta - ANSWER✔✔✔-mosses
| |
Equisetophyta - ANSWER✔✔✔-horsetails
| |
lycodiophyta - ANSWER✔✔✔-clubmosses
| |
Filicinophyta - ANSWER✔✔✔-ferns
| |
Coniferophyta - ANSWER✔✔✔-conifers
| |
Angiospermophyta - ANSWER✔✔✔-flowering plants | | |
spores and seeds - ANSWER✔✔✔-major reproductive strategies,
| | | | | | |
mosses and ferns (spore), gymnosperms and angiosperms (seed)
| | | | | | |
Flower Diversity - ANSWER✔✔✔-most amazing adaptations: flowering
| | | | | | |
plants
, Fruit Diversity - ANSWER✔✔✔-flowers evolved to attract pollinators for
| | | | | | | | |
pollination, fruits are part of the female part of the flower: ovary of the
| | | | | | | | | | | | | |
pistol. can be by wind, float in water, mechanical to disperse seeds
| | | | | | | | | | |
Bryophytes - ANSWER✔✔✔-liverworts, hornworts, mosses, simplest,
| | | | | |
nonvascular, found in moist environments, shady areas near house, near
| | | | | | | | |
water, no tissue will limit size, challenge to get nutrients if they are
| | | | | | | | | | | | | |
bigger, dominant gametophyte stage (haploid), photosynthetic stage is
| | | | | | | |
haploid, true mosses are different from Spanish moss,
| | | | | | |
Tortula - dry land moss - ANSWER✔✔✔-grows on dry plateaus in
| | | | | | | | | | |
Central Mexico |
Campylopus - ANSWER✔✔✔-moss found in extreme environments,
| | | | | | |
found in Antartica, volcanic vents warm the area up
| | | | | | | |
Taxonomy of Bryophytes - ANSWER✔✔✔-Phylum Marchantiophyta
| | | | | |
(liverworts), Phylum Anthocerotophyta (hornworts), Phylum Bryophyta
| | | | | |
