  1. Unity and Diversity of Life What characteristics do living creatures have in common?

  2. Living creatures are ORGANIZED • All made of the same collection of chemicals, but we are organized as… • molecules • proteins, fats, carbohydrates, nucleic acids carbohydrates proteins DNA

  3. Living creatures are ORGANIZED • All made of the same collection of chemicals, but we are organized as… • organelles & cells • plant cells & animal cells plant cell animal cell

  4. Living creatures are ORGANIZED • All made of the same collection of chemicals, but we are organized as… • Tissues & organs & organ systems • respiratory, circulatory, digestive, etc.

  5. Living creatures RESPOND • Respond to internal changes • Homeostasis • maintaining balanced conditions inside the body • Respond to external changes

  6. Living creatures use ENERGY • Metabolism • all the reactions your body performs to make & use energy • eating & digestion & elimination of waste • synthesis = building reactions • cellular respiration = making energy mitochondria

  7. Living creatures GROW & DEVELOP • Change over an individual’s life time • get bigger • mature • so they can reproduce

  8. Living creatures REPRODUCE • Make the next generation

  9. Living creatures perform Life Processes We can organize the life processes using a pneumonic device. Huh? T-Transport (move materials in a body/cell) R-Respiration (Transforming food into Energy) R-Regulation (Maintain internal balance-Homeostasis) R-Reproduction (Make more cells/organisms) N-Nutrition (Obtaining food) E-Excretion (To remove metabolic waste) S-Synthesis (to make complex from simple) G-Growth (To get larger)

  10. Don’t be a Dodo… Ask Questions!!
