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 organismsWithout cellsThe body can notfunction

Page 12 re-draw and explain thisFigure (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 threeExamples 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 theSimilarity between parents and their offspring?

Page 14 What are these Made of?

5. Interaction With the Environment- organisms interact their environment for example: plant uses things in its environment

for photosynthesis— Page 14 Define photosynthesisPage 14 How does a plant interact with its

environmentPage 15 How do you exchange chemicals in the

environment-give examplesPage 15 How else do you interact with environment?

6. Energy and Life

all starts with the sunPg 15 Summarize paragraph Define producers and consumersPage 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.
