2. 8 Characteristics of Living Things

3. What is an organism? A living thing!

4. What makes something “alive?” 1) Made up of Cells

5. Everything living is made of cells! Cell specialization

6. What makes something “alive?” 1) Made up of Cells 2) Obtains and Uses Energy

7. Energy comes in many forms!

8. What makes something “alive?” 1) Made up of Cells 2) Obtains and Uses Energy 3) Grows and Develops

9. Growing is different from development !

10. What makes something “alive?” 1) Made up of Cells 2) Obtains and Uses Energy 3) Grows and Develops 4) Responds to the Environment

11. What is a stimulus and a response? Stimulus - the “cause” or signal. Response- the resulting action caused by the stimulus.

12. What is an adaptation? The way that a living thing changes to better fit its environment.

13. What makes something “alive?” 1) Made up of Cells 2) Obtains and Uses Energy 3) Grows and Develops 4) Responds to the Environment 5) Reproduces

14. Most things can reproduce.

15. What makes something “alive?” 1) Made up of Cells 2) Obtains and Uses Energy 3) Grows and Develops 4) Responds to the Environment 5) Reproduces 6) Based on universal genetic code (DNA)

16. DNA is the code of life

17. What makes something “alive?” 1) Made up of Cells 2) Obtains and Uses Energy 3) Grows and Develops 4) Responds to the Environment 5) Reproduces 6) Based on universal genetic code (DNA) 7) Maintains a stable, internal environment (Homeostasis)

18. Homeostasis The balance of the internal systems of living things. Ex- Heart rate, Breathing rate, Temperature
