Plants vs Animals. Division us Phyla Prokaryotes. I. Gen info. • Gram +/- 40-80nm thicc C 4 nm cell wall Mitochondric Endosymbiotic theory. mitochondria + chloroplasts. B. Two divisions: prochlorophta = entirely marine. (all gram). has both chlorophyll A+B. •Photosynthetic (ABCD chlorophils) Acessory pigments. Pleiomorphic Thylakoids •Cyanopnyta a. Nanofossils found as stromatolites. 2/15/19 I photosynthetic Pigments. a.) Chlorophyl-a + b.) Accesory pigments. Phycobilisomes → do not do photosynthesis - c-phycocyan blue *passes other light Freq. C-pnycoerytherin dark pink to black C- allophycocyanin blue • Thallocoids C. Can control light Absorption. D. Additional Accessory Pigment b-caratene. What makes the cell wall of bacteria? II Cell walls EndosporesS a. Peptidioglycen b. Has second membrane gelatinous sheath. Goleotrichia Heterocust = Nitrogen fixation Lack of oxygen. Anabaena Non-reproductive. 000000000 Secretes more a cell wall. Spore Akinenine Acts like Survival mechanism. Anerobic: Oxugen is present 6CO2 + H2O C6H12O6 + 602 Trycnome = Straight line. doesn't divide/grow end-to- end. Ⅳ. Mitosis Fission. B/G Algae have one chromosome, starts binary 00000 unicellular, one direction. 888 2 direction. Endospores = * Hormogonium. Spore that grows in the Cell. "In gram + bacteria, do not reproduce. • In B/G Algae, can separate, are reproductive. Hyella Fairly uncommon * Merismopedia. VII. Classification. a) Order Chamaesphionales - Endo + Exo ex: Hyella + Dermocarpa b) Order Chrocoales - unicellular colonial (in two's). Chroococus Gleocapsa = Copius sheath. C.) Order: Oscillatorialis (thin gelatinous sheath) Filamentous, bascillus, cocci, Spiral 2. Examples a. Oscillatory Bacilli, No heterocyst or Akinetes b. Lynba difference in Sneath (Lunba = thicc-er). Most common organism alive (Found every where). C. Spirulina - "worm-shaped", grown commercially, can't grow it hypersaline. 45-50% Protein. d. Rivulariaea - 08000000 ex: Gleotrichia Strepto ex: Rivularia e. Nostocules- 8888 Staph ex: Nostoc ex: Anabena. * Faculative Aneorobe = Oxygen levels don't matter. Final Land plants = Genus, & Common Algae = Genus Division Chlorophyta - Green Algae 3/1/19 Cellulose, Alpha Some are unicellular, colonial, macro, micro... used to include with land plants → Most unicellular or alternation generation: Sometimes. macroalgae
