7 Life Cycles Required for Bio 1B Plant/Fungi Midterm Exam Required Life Cycles Basidiomycete Fungal Life Cycle (Fig 31.19, 31.5) Clamydomonas (unicellular Green Algae) Life Cycle (Fig 28.22) Alternation of Generations (Fig 29.5) Ulva ( multicellular Green algae) Life cycle Laminaria (multicellular Brown algae) Life Cycle (Fig 28.18) Bryophyte (non-tracheophyte) Moss Life Cycle Fern (non-seed Tracheophyte) Life Cycle Pine Gymnosperm Life Cycle (Fig 30.6) Angiosperm Life Cycle (Fig 30.10, 38.2, 38.3, 38.5, 38.7) 8 Botany/Fungi Section Foci “Tree of Life” and phylogenetic relationships Diversity of basal eukaryotes, algae, land plants, & fungi Reproduction strategies of organisms within these major groups Anatomy/morphology form & function Human uses as foods, medicines, fiber, & wood 9 See the Forest through the Trees: Introduction of the major groups of organisms based on the phylogenetic relationships 10 Domains Bacteria Archaea Eukarya • Algae Land plants • Fungi • Animals 11 Three Domains of Living World Bacteria Archaea Eukarya Major Groups of Organisms (see Figs 26.22, 27.12, Table 27.2) Prokaryotes (lack nuclei, organelles, & sexual reproduction) Bacteria (e.g., cyanobacteria) Archaea Eukaryotes (have nuclei, organelles, & sexual reproduction) protozoans, slime molds, dinoflagellates, water molds, mildew, diatoms, algae Land Plants (bryophytes, pteridophytes, gymnosperms, angiosperms) Fungi Animals 12 Prokaryotes Photosynthetic cyanobacteria gave earth its first oxygen atmosphere 1.8 billion years ago Beneficial or pathogenic bacteria in animals & humans Nitrogen-fixing bacteria & archaea have profound effect on the productivity of natural ecosystems and agroecosystems

13 Cyanobacteria Gave Earth its first oxygen atmosphere starting 1.8 billion years ago Possess chlorophyll that is not bounded by membranes into organelles like chloroplasts Currently discussed theory on origin of chloroplast suggests that: cyanobacteria-type organisms became incorporated into early eukaryotes and evolved into chloroplasts (Fig 28.2)
