1.2 Diverse Forms of Life

1.3 Ten Themes of Biology

Where do you live?

1.1 Identify major organizational levels of life.

The Biosphere




DNA and Genes

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?

small to big

There are Three Domains of Life (Biggest

Groups that a species can live in)




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)


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


Biological Systems

Bike, computer, your body,

Eco systems

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

Without cells

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

Made of?


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-

Two from paragraph:

Two from figure?


Scientific Inquiry-Biology is a science and, as such, relies on certain processes of inquiry
