  1. Get out your spirals!Characteristics of Life Essential Questions: What are the major (7/8) characteristics of life? Complete an Arcostic to remember the characteristics

  2. Explore: The Biology Song! • Watch the short YouTube video called “The Biology Song.” (Why is it called the biology song?) • Record any descriptions you see/hear about what makes something living or a living organism. • The Biology Song Write your ideas in The box on your Notes sheet.

  3. 1. Composed of Cells • All living things are composed of one (unicellular) or more (multicellular) cells. • Unicellular – you cant see with the eye • Multicellular – you can see • Organism – Displays all characteristics of life and considered by biologists to be alive.

  4. 2. Require Energy • Living organisms require energy • Heterotrophs • Obtained through the breakdown of food and nutrients. • Autotrophs • Obtained through sunlight or chemical compounds • (Photosynthesis, Chemosynthesis)

  5. 3. Reproduce and Grow • All living things reproduce to carry on their species. • asexual reproduction- Some plants and bacteria reproduce individually • sexual reproduction- some plants and animals reproduce with another member of their species

  6. 4. Have DNA (Display Heredity) • DNA & RNA are the codes or sequences that get translated into all types of proteins.

  7. 5. Respond to Stimuli • living things respond to changes in light, heat, sound, and chemical and mechanical contact. • Once a stimulus has been received by the organism, that triggers a response.

  8. 6. Adapt (Evolves) to their Environment • Organisms and Species adapt to their environment in order to survive. • Add fat/fur in the wintertime. • Changing coat colors to elude predators. • Learned behaviors to avoid harm.

  9. 7. Maintain Homeostasis • All organisms maintain a stable internal balance, also known as homeostasis.Example • You workout • Your cell temp increases • You sweat • Your cell temp decreases

  10. 8. Evolve (over time) • All organisms in a population evolve to the changing environment over time. Example: The loss or no use for wisdom teeth Humans have grown in height over time Horses used to be the size of a dog!

  11. Reflect: The Biology Song! • Re-watch the short YouTube video called “The Biology Song.” • Did you hear anything different this time? • Why is it called the Biology song? • The Biology Song

  12. What am I? Living or Non-Living? • In the following slides, you will see a picture of an object. • Observe the object. (Quantitative and Qualitative) • Feel free to ask questions about the object. • Identify the aspect of living things it represents. • (Remember, it must meet all criteria to be considered a living organism!) • Determine if it is Living or Non-Living! …We’ll start of easy…
