  1. Welcome to Mrs. Boehling’s Biology Room 204 Power Point by : Susan Boehling, SGHS, NC Adapted from: Alicia Carlucci, SGHS, NC Kelly Riedell, Brookings High School, SD

  2. What is Biology? • Biology is the study of _____________. • Also examines the relationships among living things • Scientists use the __________________ to study this life. living things Scientific Method

  3. BIOLOGY Bacteria Image from: http://analyzer.depaul.edu/astrobiology/kingdoms.jpg

  4. The Scientific Method • Ask a question (based on observation) • Form a hypothesis (inference or prediction) • Set up a controlled experiment • Record and analyze results • Draw a conclusion

  5. Characteristics of Living Things

  6. Alive? No… Rocks are considered non-living matter.

  7. Alive? staff.jccc.net YES!!! Lithrops: “rock like” plant from South Africa

  8. Alive? www.sofeminine.co.uk YES!!! Here the living “Rock” is sitting on some non-living rock.

  9. What makes something living? cells • Made of _________ • _____________ • Based on a _____________________ • _______ and ____________ • ______ & ___ ____________& _______ • ________ to their ____________ • ______________________________ • As a group, __________________ Reproduce universal genetic code Grow develop Obtain use materials energy Respond environment Maintain a stable internal environment change over time

  10. 1. All Living Things Are Made of Cells CELL The _____ is the basic unit of life. Unicellular Organisms Multicellular Organisms

  11. 2. All Living Things Reproduce All living organisms make other organisms like themselves reproducing in two ways: • Asexual reproduction- • Sexual reproduction-

  12. Asexual Reproduction— • Single celled organisms reproduce this way. • The cell divides creating an exact replica of itself. • Asexual reproduction produces traits the same as the parents.

  13. Sexual Reproduction— • Two separate organisms unite to produce an offspring. • Sexual reproduction produces traits different from the parents • This is an advantage as it creates a genetic diversity to assure survival of the species.

  14. 3. All Living Things Are Based on a Universal Genetic Code • DNA • Inherit traits from the parents • A segment of material with instructions for one trait is called a ________. gene

  15. 4. All Living Things Grow and Develop • Grow larger • Differentiation of cell types

  16. 5. All Living Things Obtain & Use Materials & Energy • To grow and develop • Metabolism- chemical reaction in which an organism breaks down material i.ehow.com/images/GlobalPhoto/ Articles/461648.

  17. 5. All Living Things Obtain & Use Materials & Energy AUTOTROPHS www.munshibari.com/ image/sun_in_tree.png ___________________ HETEROTROPHS ______________ use energy from sunlight or chemicals to make their own food. (green plants use photosynthesis) ______________ get their energy by consuming other organisms. (animals and most bacteria) www.edge.org/3rd_culture/myhrvold_lions07/images/500/lion-carrying-impala-500.jpg

  18. All Living Things Respond to Their Environment • Respond to stimuli www.wunderground.com

  19. 7. All Living Things Maintain a Stable Internal Environment • Must be ok on the inside • Homeostasis- process by which an organism keeps its internal conditions stable

  20. HOMEOSTASIS involvesinternal __________ mechanisms FEEDBACK If body temp drops too low, “shivering” produces heat to warm you up. If temp is too hot, “sweating” cools you down.

  21. 8. All Living Things Change Over Time • Living things evolve

  22. cells Reproduce universal genetic code Grow develop Obtain use materials energy Respond environment Maintain a stable internal environment change over time • Made of _________ • _____________ • Based on a _____________________ • _______ and ____________ • ______ & ___ ____________& _______ • ________ to their ____________ • ______________________________ • As a group, __________________
