1 Emergence of Modern Science The Cell

2 How did life begin? What is a cell, and why is it so important to life? Is a virus alive? How are living organisms organized? What are tissues, organs, and organ systems?

3 Cell Theory Leeuwenhoek Hooke Schleiden and Schwann All living things are composed of cells The cell is the fundamental unit of life All cells arise from previous cells

4 Prokaryotes and Eukaryotes Prokaryotes Archaea Bacteria Eukaryotes Protista Plants Animals

5 The World of Prokaryotes Aerobes Anaerobes Facultative anaerobes Obligate anaerobes Extremophiles

6 Monera Bacteria (eubacteria) Archaea (archaebacteria) Cyanobacteria (blue-green algae)

7 Bacterial Diversity Proteobacteria Alpha Proteobacteria Beta Proteobacteria Gamma Protobacteria Delta Protobacteria Epsilon Protobacteria Chlamydias Spirochetes Gram-Positive Bacteria Cyanobacteria

8 Prokaryotic Cells Size Shape Cocci Bacilli Spirilla spirochetes

9 Nutrition Photoautotrophs cyanobacteria Chemoautotrophs Nitrogen Fixation Methanogens Sulfur reducing Photoheterotrophs Chemoheterotrophs Saprophytes parasites

10 Eukaryotes Protists Plants Fungi Animals

11 Plant Cell

12 Animal Cell

13 Cell Membranes Phospholipid Bilayer

14 Cell Nucleus Chromosomes Eukaryotes Nucleolus Prokaryotes Plasmids

15 Organelles Chloroplasts Endoplasmic Reticulum Ribosomes Mitochondria Golgi Apparatus

16 Vacuoles and Vesicles Water Vacuoles Food Vacuoles Vesicles Lysosomes

17 Cellular Metabolism Photosynthesis Respiration Anaerobic Respiration (Fermentation) Aerobic Respiration

18 Glycolysis Krebs Cycle

19 Cellular Reproduction Mitosis Meiosis

20 Development

21 Quiz 1. T or F, prokaryotes lack organelles. 2. T or F, the cell membrane is semi-permeable. 3. T or F, the mitochondria are the powerhouse of the cell. 4. T or F, Meiosis forms gametes. 5. T or F, the blastula is the 4 cell stage of development.
