Chapter 1 The Scope of Biology1.1 Global to
Microscopic1.2 Diverse Forms of Life1.3 Ten
Themes of Biology
2
Where do you live?
  • Country
  • State
  • City
  • Street
  • House

3
1.1 Identify major organizational levels of
life.
  • The Biosphere
  • Ecosystems
  • Organisms
  • Cells
  • DNA and Genes
  • Define each of these terms

4
Concept Check
  • Page 6 1-3
  • Page 20 1-2

5
How many different types of organisms do you
think are on our schools campus? How would a
rainforest (beach) be different than our
campus?Define the term species
1.2 Use the term species in discussing life's
diversity.
6
  • 1.2 Explain the basic strategy biologists use in
    classifying organisms.
  • Millions of species inhabit Earth
  • Biologists use Classification
  • to keep track of species
  • Page 8 1st paragraph give examples and how are
    butterflies sorted?
  • How is your address-a classification system?
  • What other classification systems can you think
    of?

7
small to big
8
  • There are Three Domains of Life (Biggest Groups
    that a species can live in)
  • Archaea
  • Bacteria
  • Eukarya
  • 4 Kingdoms in eukarya
  • protists, fungi, plants, animals
  • Page 9 Define 4 bold terms

9
  • Archaea and Bacteria
  • all unicellular-one cell
  • prokaryotic no nucleus (DNA floats around the
    cell)
  • Eukarya
  • Mostly multicellular (many cells)
  • some unicellular
  • Eukaryotic- nucleus surrounds DNA
  • What ways are Eukarya different from Archaea
    and Bacteria?

  • Page 20 3,9,19

11
1.3 Identify ten themes of biology
  • Biology studies over 1.5 million species but all
    have things in common.
  • 10 Themes are used in this text to unify all life
  • Pages 11-19- list the 10 themes

12
1.
  • Biological SystemsBike, computer, your body,
    Ecosystems All levels of life are part of
    systems
  • Pg 11 Define System
  • Pg 12- How is an Ecosystem a system? Explain
    figure 1-9
  • Pg 12- Does system apply from Biosphere to
    cell levels of life?

13
2.
  • Cellular basis of life cells make up
    tissues make up organs organs make up
    systems systems make up organismsWithout
    cellsThe body can notfunction
  • Page 12 re-draw and explain this
  • Figure (use paragraph and picture)

14
  • 3.
  • Form and function- How something works is related
    to its structure. In other words, form fits
    function
  • Page 13 Give three
  • Examples of this
  • theme.
  • Use figure 1-11

15
  • 4.
  • Reproduction and Inheritance"Like begets like
  • Offspring inherit units of information called
    genes from their parents.
  • Page 13 What explains the
  • Similarity between
  • parents and their offspring?
  • Page 14 What are these
  • Made of?

16
  • 5.
  • Interaction With the Environment-
  • organisms interact their environment
  • for example plant uses things in its
    environment for photosynthesis
  • Page 14 Define photosynthesis
  • Page 14 How does a plant interact with its
    environment
  • Page 15 How do you exchange chemicals in the
    environment-give examples
  • Page 15 How else do you interact with
    environment?

17
  • 6.
  • Energy and Lifeall starts with the sun
  • Pg 15 Summarize paragraph
  • Define producers and consumers
  • Page 16 Why do we eat? How does food change?
  • Why does life depend on a continuous supply of
    energy from the sun?

18
  • 7.
  • Regulation-Mechanisms that let organisms regulate
    their internal environment, despite changes in
    their external environment
  • example homeostasis, or "steady state."
  • Page 16 What is an example of homeostasis?

19
  • 8.
  • Adaptation and Evolution
  • an inherited trait that helps the organism's
    ability to survive in its particular environment.
  • Page 17 Define Population, Natural Selection
  • Explain the figures

20
  • 9.
  • Biology and Society-
  • Page18 what are some current events related to
    Biology
  • Two from paragraph
  • Two from figure?

21
  • 10.
  • Scientific Inquiry-Biology is a science and, as
    such, relies on certain processes of inquiry
  • Page 19- What is inquiry?
