Ferns. Gymnosperms. Angiosperms. Gnetum. Description: (some apply to other Gnetales) Monoecious or dioecious
Ferns. Sarah Burns Kellen Kristoffersen Matt Berard Graham Helfer. Important Information. There are 12,000 species of ferns They are the largest most diverse group of seedless vascular plants They are native to the tropics but are found in homes and gardens
Ferns. Kaiti Xouris, Preston Hickson,Taylor Contini, Nelly Kruglyak. Origins. Phylum: Pterophyta – consists of about 11,000 species Lower Devonian Tropical Biome All but dry land. Evolution of the Fern.
Ferns. Phylum Pterophyta. How did we get here?. Evolution is the derivation of progressively more complex forms of life from simple ancestors; Charles Darwin proposed that natural selection is the principle mechanism by which evolution takes place. Natural Selection.
autotrophic vascular plants. Ferns. Ferns have xylem and phloem . But they are without flowers or seeds. Ferns reproduce using spores. These spores are held underneath the leaves of adult plants. Ferns can live in a variety of habitats from Mountains-Deserts.
Ferns. Alternation of generations. Zygote created from egg & sperm. Alternation of generations. Zygote divides by mitosis to create adult sporophyte. Alternation of generations. Haploid spores created by meiosis. Alternation of generations. Haploid spores released into air.
