Chapter 1 The Scope of Biology
1.1 Global to Microscopic
1.2 Diverse Forms of Life
1.3 Ten Themes of Biology
DNA and Genes
Define each of these terms
Page 6 #1-3
Page 20 #1-2
1.2 Use the term
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 1 st paragraph give examples and how are butterflies sorted?
How is your address-a classification system?
What other classification systems can you think of?
There are Three Domains of Life (Biggest
Groups that a species can live in)
4 Kingdoms in eukarya: protists, fungi, plants, animals
Archaea and Bacteria all unicellular-one cell prokaryotic –no nucleus (DNA floats around the cell)
Mostly multicellular (many cells) some unicellular
Eukaryotic- nucleus surrounds DNA
What ways are Eukarya different from Archaea and Bacteria?
Page 9 #1-3
Page 20 #3,9,19
Biology studies over 1.5 million species but all have things in common.
10 Themes are used in this text to unify all life
Bike, computer, your body,
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?
Cellular basis of life
cells make up
tissues make up organs
organs make up systems
systems make up organisms
The body can not function
Page 12 re-draw and explain this
Figure (use paragraph and picture)
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
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
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 ?
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?
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?
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
Biology and Society-
Page18 what are some current events related to
Two from paragraph:
Two from figure?
Scientific Inquiry-Biology is a science and, as such, relies on certain processes of inquiry
Page 19- What is inquiry?
