4. 1. Cellular Organization Orderly cellular structure of an organism All living things are made up of one or more cells This structure allows the parts of an organism to work together as a living system

6. 3. Growth and Development All living things begin as one cell Cells undergo growth and development Different cells of different organisms grow and develop differently

7. 4. Homeostasis (Maintaining stability/Adjusting to surroundings) Organisms constantly interact with the nonliving and living surroundings All living things respond to changes in their environment in order to survive

8. Do Now, Revisited Now knowing the characteristics of life, are the following living or not?
