  1. The 7 Themes of Biology

  2. Biology • Biology – The study of LIFE! • Anything considered alive share the following 7 characteristics

  3. 1. Cells • All living things are made of one or more cells • The cell is the basic structure of all living things

  4. 2. Reproduction • All living organisms reproduce • Sexual reproduction creates genetic variation • Asexual reproduction creates exact copies

  5. 3. Metabolism • Metabolism - All the chemical reactions that create and use energy to run all living processes • Plants capture the energy of the sun and convert it to food • All other organisms eat the plants or they eat the animals that eat the plants

  6. 4. Homeostasis • Homeostasis – maintaining a stable internal environment in spite of external changes • Balancing internal conditions with external conditions

  7. 5. Heredity • Passing on characteristics to the next generation • Genes carried on DNA are passed from parent to offspring

  8. 6. Evolution • Changes in the traits of species over time • Individuals with the best traits for their environment will survive and pass on their genes to the next generation

  9. 7. Interdependence • The interaction of living organisms with each other and with their environment • Dependence on one another and the ecosystem
