  3. Introduction Mrs. Hamilton

  4. Chapter 1 The Scope of Biology

  5. Concept 1.1 • Biology explores life from the global to the microscopic scale. • Key Terms • Biosphere • Ecosystem • Organism • Cell • DNA • Gene

  6. The Biosphere • Signs of life at the Global Scale • Consists of all the parts of the Earth that are inhabited by living things

  7. Ecosystems • Community of living things in an area, along with the nonliving features of the environment that support the living community • Woodland Ecosytem

  8. Organisms • Individual living things • Large • Small • Microscopic

  9. Cells • Life's basic units of structure and function • All organisms are made of one or more cells

  10. DNA & Genes • DNA is the chemical responsible for inheritance, and is found in the nucleus of every cell • Spread in bits and pieces along the DNA molecule are genes – which code for specific proteins

  12. Concept 1.2 • Biology explores life in its diverse forms • Key Terms • Species • Domain • Unicellular • Prokaryotic cell • Eukaryotic cell • Multicellular

  13. Life’s Diversity of Species • Biodiversity – the variety of life on Earth • What does it mean to have biodiversity?

  14. Interactive Lesson • http://www.pearsonsuccessnet.com/snpapp/iText/products/0-13-115075-8/index.html

  15. Classifying Life: The Basic Idea • As humans we tend to group items in categories • Classification as a postal address

  16. The Three Domains of Life • Archaea – prokaryotic, unicellular • Bacteria – prokaryotic, unicellular • Eukarya – eukaryotic, multicellular

  17. Concept 1.3 • Ten themes unify the study of life • Key Terms • System • Photosynthesis • Producer • Consumer • Homeostasis • Adaptation • Population • Natural Selection • Evolution

  18. 1 – Biological Systems • “The whole is greater than its parts” • A system has properties based on the arrangement and interactions of its parts • Interactions with organisms and the non-living parts of the environment “put the system in ecosystem”

  19. 2 – The Cellular Basis of Life • All organisms are made of cells • These cells are then organized into more complex structures

  20. 3 – Form and Function • Which is the better tool – hammer or screwdriver? • The best form depends on its function • Would a flipper help a bird fly? • Would a fish be able to swim with feathers?

  21. Beak Design • Scooping fish from water • Eating large prey • Eating nectar from a flower • Eating seeds • Eating insects from dead trees • Probing mud for invertebrates • Catching insects in flight

  22. 4 – Reproduction and Inheritance • Organisms have to be able to reproduce • Using genetic information (DNA) from parents you can see how it is passed along from generation to generation

  23. 5 – Interaction with the Environment • No organism is isolated from its surroundings • Photosynthesis – uses carbon dioxide, water, and sunlight to produce oxygen and energy • Stepping out into the sunlight – causes you to squint • Venus flytrap – designed to detect touch which causes them to close

  24. 6 – Energy and Life • Moving, growing, reproducing and other life activities require energy • You can trace energy (light, chemical, and heat) in different ecosystems • Producers (Autotrophs) vs. Consumers (Heterotrophs)

  25. 7 - Regulation • Organisms have to regulate the internal conditions • The ability of birds and mammals to regulate body temperature is an example of homeostasis (steady state) • Mechanisms of homeostasis enable organisms to regulate their internal environment, despite changes to their external environment

  26. 8 – Adaptation and Evolution • Adaptations are inherited traits that help the organism survive and reproduce in a specific environment • Evolution means “change over time” – specifically a generation to generation change that occurs over a long period of time

  27. 9 – Biology and Society • The more we learn about biology – the more it impacts daily life • Medicine • Environmental Issues

  28. 10 – Scientific Inquiry • Involves asking questions about nature and then using observations or experiments to find possible answers to those questions
