  2. Living Things: • Are ORGANIZED • AQUIRE MATERIALS & ENERGY • REPRODUCE • RESPOND TO STIMULI • Are HOMEOSTATIC • GROW & DEVELOP • Are ADAPTED TO THEIR ENVIRONMENT

  3. 1. Living things are ORGANIZED • they have levels of organization Cells Tissues Organs Organ systems atoms molecules Organisms

  4. Levels of Organization http://sph.bu.edu/otlt/MPH-Modules/PH/PH709_A_Cellular_World/organization2.png

  5. 2. Living things AQUIRE MATERIALS & ENERGY • Requires an outside source • Plants convert sunlight to chemical energy • Animals consume food break it down to nutrients provides energy & building blocks

  6. 3. Living things REPRODUCE • Make more of themselves • Essential for the survival of the species • Say no more … for now!

  8. 5. Living things are HOMEOSTATIC • The internal environment stays relatively the sameregardless of changes in the external environment • ALL organ systems help maintain homeostasis • VERY IMPORTANT in Biology 12!!!

  9. 6. Living things GROW & DEVELOP • GROWTH is: - an increase in size - part of development • DEVELOPMENT is ALL of the changes that occur between conception & death

  10. 7. Living things are ADAPTED TO THEIR ENVIRONMENT • ADAPTATIONS are modifications that make an organism more suited to its way of life survival … NOT extinction! • Part of evolution

  11. CREDITS… • Information taken from Mader’s Inquiry Into Life, 11th Ed., p. 3 – 5 • Clipart: (& friends) • Levels of Organization diagram: http://sph.bu.edu/otlt/MPH-Modules/PH/PH709_A_Cellular_World/organization2.png
