1. Six Characteristics of Living Things • Composed of cells. • Complex organization patterns • Use energy. • Have stable internal conditions. • Grow and change. • Reproduce

2. 1. All Living Things are Composed of Cells Eukaryotic Cell Two types of cells: • Prokaryotic Cells Most are single- celled organisms • Eukaryotic Cells Prokaryotic Cell Back to Menu

3. 2. Complex Organization Patterns • Atomic Level • Molecular Level • Organelle Level/ Cellular Level • Tissue Level • Organ and Organ System Levels

4. 2. Complex Organization Patterns • Organism Level • Population Level • Group of same species • Community Level • Groups of different species • Ecosystem Level • Living and non-living elements • Biosphere Level Back to Menu

5. 3. All Organisms use Energy Sunlight Which level of organization is represented here? Ecosystem Producers (plants and other photosynthetic organisms) Heat Chemical Energy Consumers (including animals) Heat

6. 4. All organisms have stable internal conditions which must be maintained in order to remain alive. This is called homeostasis. Brrr…. Shiver… I am so cold! Acceptable Range 37⁰C Back to Menu

7. 5. All organisms grow and change. • Changes occur during the life cycle of an organism. • Some changes are inherited, which over time are called __________. adaptations

8. 5a. Changes occur during an organism’s lifetime cvcvcc • Differentiation: The process by which cells become increasingly different and specialized cvcvcc Back

9. 5b. Organisms Adapt Back to Menu • The inheritance of adaptations over time is evolution.
