  1. may reach more than a meter in height • contain vascular tissues • tracheids in xylem • phloem • lignin-reinforced cell walls • with true roots, stems, and leaves http://yahyaaydin.edublogs.org/files/2012/06/vascular-system-1oiqdco.gif

  3. Early vascular plants • seedless • leaves with waxy cuticles • sporophyllswith spores arranged in sori(sing. sorus) • depend on water for reproduction and nourishment • dominant diploid sporophyte stage http://3.bp.blogspot.com/_ardEXc55Vv4/S8JwWU7xbQI/AAAAAAAAAH4/FtPJLKeifBo/s1600/Fern_labeled_MC_%5B1%5D.jpg

  5. Taxonomy • whiskferns have rhizoids with mycorrhizae, stems, and leaflike structures • Psilotum http://www.redorbit.com/media/uploads/2004/10/45_0d6f53866162cdab6d2a37a3a3101ea9.jpg

  6. Taxonomy • abundant on early earth • first forests • grew to 35m tall • fossilized remains  coal • extant species are club mosses in moist places (Lycopodium) http://www.twofrog.com/images/lycopodium98.jpg, http://upload.wikimedia.org/wikipedia/commons/3/33/Lycopodium_saururus.JPG

  7. Taxonomy • Equisetum (horsetail/scouring rush) only living genus • can grow to a meter in length • leaves arranged in whorls around stems • contain abrasive silica http://www.friendsschoolplantsale.com/wp-content/uploads/2008/03/equisetum.jpg, http://www.irishwildflowers.ie/images/fern-allies/fa-07a1.jpg, http://www.missouriplants.com/Ferns/Equisetum_hymenale_stems.jpg

  8. Taxonomy • since 350 mya • true vascular tissues, strong roots, underground stems called rhizomes, large leaves called fronds • shade plants found in wet habitats • sporangia in clusters of soriproducing haploid spores • released spores carried by wind/water http://www.friendsschoolplantsale.com/wp-content/uploads/2008/03/equisetum.jpg, http://www.irishwildflowers.ie/images/fern-allies/fa-07a1.jpg, http://www.missouriplants.com/Ferns/Equisetum_hymenale_stems.jpg

  10. water NOT required for gamete fertilization! • gametes in sporophyte structures called flowers or cones • undergo pollination to transfer sperm from male gametophyte (in pollen grain) to female gametes • embryos contained within seeds with stored food supplies http://biology.clc.uc.edu/graphics/taxonomy/plants/spermatophyta/gymnosperms/other%20pines/JSC%209805&06%20male%20&%20female%20pine%20cones%203.JPG, http://growit.umd.edu/vegetableprofiles/VegetableProfileImages/squash.mf.petals.jpg

  12. with vessel elements similar to angiosperms Taxonomy Welwitschia wikipedia.org , http://ephedraclaims.com/wp-content/themes/thesis_17/custom/rotator/ephedra1.jpg Gnetum

  13. grow very slowly and are long-lived (~1000 years) palmlike plants with large cones plants are dioecious (plants have separate sexes) Taxonomy Cycasrevoluta http://www.hear.org/starr/images/images/plants/full/starr-080716-9529.jpg

  14. “living fossil” with only one extant member Taxonomy Ginkgo biloba http://www.arborday.org/trees/graphics/trees/162/162_md.jpg,, http://i.ebayimg.com/t/Spring-Valley-Herbal-Supplement-Ginkgo-Biloba-90-ct-/00/s/MzAwWDMwMA==/$(KGrHqR,!jQE68o5+uJ1BO+Z!wKzwQ~~60_35.JPG

  15. Taxonomy • pine, spruce, fir, cedar, sequoia, redwood, yew, larch, cypress • long and thin leaves with waxy cuticles and sunken stomates

  17. Characteristics • Appeared on land during the Cretaceous period 135 mya • Dominant and most diverse form of plants • Reproductive organs called flowers with ovaries that surround and protects seeds • Ovaries  fruits (tissue surrounding seeds)
