Botanical Diversity - Must Take With Biol 3071 Crn 1514 (BIOL 3070) Update

1st evidence of endosymbiotic theory - Mitochondira, chloroplasts and prokaryotes all have the same characteristics 2nd evidence of endosymbiotic theory - Chloroplasts and mitochondria passed to their next generations different things 3rd evidence of endosymbiotic theory - Some organisms engulf unicellular algae that function as chloroplasts Class Monocotyledonae (Liliopsida) families; - Classification of the tree Magnolia grandiflora • Phylum Magnoliophyta • Class: Dicotyledonae (Magnoliopsida) • Order: Magnoliales • Family: Magnoliaceae • Genus: Magnolia • Species: grandiflora Describe a dandelion - Inflorescence with only ray florets, each positil has hair like bristles attached at top of elongated ovary. Whorled leaves, entire plant edible, contractile roots Describe a reservoir (gullet) - Invaginated area, site of flagella attachment, where food isingested, where contractile vacuole empties waste. Describe a volvox - Hollow colony of hundreds of chlamy like cells, asexual reproduction and sexual. Describe Aloe :M - Tropical, whorled at base, leaves with mucouslike polysaccharide Describe an eyespot: - Modified portion of a single chloroplast Describe Archaebacterial - Most primitive, livesin very harsh environments, polysaccharide (carbs and sugar) cell wall, lack peptidoglycans, (peptides and sugars) Describe archaeplastida super group - Organisms with chloroplasts similar to cyanobacteria cells, chloroplasts derived from endosymbiosis of cyanobacteria, chlorphyta, plants Describe Asteraceae family :D - Sunflowerfamily, called asters, inflorescence Describe Bryophytes - Common name of plants that lack vascular tissue,so no leaves or roots. small and abundant in wet environments Describe cactaceae family :D - Inhabit desert regions, • Bright flowers • Spines CAM reactions and fibrous roots Describe camrian explosion - 0.5 BYA, 1000s of new species, marine algae, unknown reason for development, major groups of invertebrates including algae first appear here.
