Presentation Transcript


1. XII. Plantae A. Description B. Reproduction C. Nonvascular & Vascular D. Plant Groups & Divisions

2. A. Description 1. Most are photosynthetic autotrophs, exception- Cuscuta Grammica 2. Unicellular & multicellular with cell walls of cellulose 3. Chlorophyll A & B, primary photosynthetic pigments and carotenoids & xanthophyll, accessory pigment

3. B. Reproduction 1. Asexual 2. Sexual 3. Alternation of Generations

4. 1. Asexual Progeny a. Genetically identical clones b. Adventitious plantlets, runners, rhizomes, suckers, & tubers

5. 1. Sexual Progeny a. Genetically diverse b. Fertilization, seedless plants c. Pollination then fertilization, seed-bearing plants d. Isogamy vs heterogamy e. Alternation of Generations- sporophyte stage, sporic meiosis, & gametophyte stage

6. 3. Alternation of Generations

7. C. Nonvascular or Vascular 1. Nonvascular- low to ground found in moist or aquatic environments; algae, mosses, & allies 2. Vascular (Tracheophytes) - most are taller with true roots, stems, & leaves to transport water, nutrients, & waste; ferns, gymnosperms, & angiosperms

8. D. Plant Groups & Divisions 1. Seedless Plants 2. Seed-bearing Plants

9. 1. Seedless Plants a. Nonvascular Aquatic Seedless Plants b. Nonvascular Terrestrial Seedless Plants c. Vascular Seedless Plants

10. a. Nonvascular Aquatic Seedless Plants 1.) Chlorophyta- green algae 2.) Rhodophyta- red algae

11. 1.) Chlorophyta a.) Mostly freshwater, also marine & even moist soil b.) Cell wall of cellulose, chlorophyll a & b, & starch inside chloroplasts c.) Some have orange, red, or rust pigments d.) Unicellular- Chlorella & Chlamydomonas, Colonial- Volvox, Filamentous- Spirogyra, & Multicellular- Ulva

12. Desmid sp. http://www.morning-earth.org/Graphic-E/CYCLING/CYCLES%20IMAGES/cycle_in_desmid.jpg 1.) Chlorophyta- green algae

13. Cymopolia barbata www.hrw.com 1.) Chlorophyta- green algae

14. 1.) Chlorophyta- green algae d.) Chlamydomonas sp. http://www.keweenawalgae.mtu.edu/ALGAL_IMAGES/chlorophyceans/Chlamydomonas_p12_osceolapt6a_402.jpg

15. d.) Chlamydomonas sp (1.) Unicellular (2.) <25mm long (3.) Asexual or haplontic with isogametes

16. d.) Chlamydomonas sp

17. d.) Chlamydomonas sp

18. (1.) Colonial, thousands of flagellated cells, individuals resemble single Chlamydomonas (2.) Flagella beat in coordination (3.) Asexual or sexual, heterogametes

20. (1.) Filamentous, end-to-end chain of cells (2.) Form mats in ponds & streams (3.) Asexual or sexual, haplontic

23. (1.) Multicellular, sea lettuce (2.) < 1m (3.) Alternation of generations, isogametes, flagellated spores

24. 2.) Rhodophyta- red algae a.) Red pigments allow absorption of high energy, short l light, so live in deeper water b.) Simple filaments to 1m, warm marine c.) Coralline- cell walls with CaCO3 in some d.) Agar- capsules, culture & electrophoresis medium

25. Cymopolia barbata www.chekjawa.nus.edu.sg/ria/text/118.htm 2.) Rhodophyta- red algae

26. b. Nonvascular Terrestrial Seedless Plants 1.) Bryophyta- mosses, Hepatophyta- liverworts, & Anthocerophyta- hornworts 2.) Dominant gametophyte

27. 1.) Bryophyta- mosses Homolathecium nutalli? www.discoverlife.org/nh/tx/Plantae/Bryophyta

28. 1.) Hepatophyta- liverworts Asterella californica www.discoverlife.org/nh/tx/Plantae/Hepatophyta

29. 1.) Anthocerophyta- hornworts Phaeoceros sp. www.discoverlife.org/nh/tx/Plantae/Anthocerophyta

30. c. Vascular Seedless Plants 1.) First tracheophytes- true roots, stems, & leaves with xylem & phloem 2.) Dominant sporophyte 3.) Xylem- H2O & minerals from roots; Phloem- sugars & products from leaves 4.) Psilophyta- whisk ferns, Lycophyta- club mosses, Sphenophyta- horsetails, & Pterophyta- true ferns

31. 4.) Lycophyta- club mosses Lycopodium obscurum www.plants.usda.gov/java/profile?symbol=LYOB

32. 4.) Psilotophyta- whisk ferns Psilotum nudum www.washjeff.edu/greenhouse/Pnudum/

33. 4.) Sphenophyta- horsetails Have SiO2 hence scrub plants Equisetum arvense http://www.tcnj.edu/%7Emckinney/Equisetum%20May%2002-1.jpg

34. 4.) Pterophyta- true ferns Sorri on the backside of the sporophyte leaves http://faculty.etsu.edu/mcdowelt/Pictures%20Use/Botrychium%20virginianum.JPG
