1.1 Identify major organizational
levels of life.
The Biosphere

1.2 Use the term species in discussing life's
diversity.
How many different types of organisms do
you think are on our school’s campus?
How would a rainforest (beach) be different
than our campus?
Define the term species
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?
small to big
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
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?

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
1.
Biological Systems
Bike, 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?
2.
Cellular basis of life
cells make up
tissues make up organs
organs make up systems
systems make up organisms
Without cells
The body can not
function
Page 12 re-draw and explain this
Figure (use paragraph and picture)
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
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?
5.
Interaction With the Environmentorganisms 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?
6.
Energy and Life
all 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?
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?
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
9.
Biology and SocietyPage18 what are some current events related to
Biology
Two from paragraph:
Two from figure?
10.
• Scientific Inquiry-Biology is a science and, as
such, relies on certain processes of inquiry
