1. Chapter 6 Lesson 1 Classifying Living Things
Ms. Amanda and Ms. Diana

2. How can you tell whether it is alive?
Living things share several basic characteristics.
What do you have in common with other living things such as a bug or a tree?
What characteristics does the flame have that would lead some people to think the flame is alive?
What qualities did you think of earlier (that you share with other living things) that the candle does not possess?
What characteristics do you think something must have to be considered alive?

3. What are living things? Living things are made of cells.
All living things have six characteristics in common:
Living things are made of cells.
Living things are organized.
Living things grow and develop.
Living things respond to their environment.
Living things reproduce.
Living things use energy.

4. Living things are made of cells
Some living things are unicellular, which means they are made up of only one cell.
Many living things are made of more than one cell and are called multicellular organisms.
Multicellular organisms can have several layers of organization.

5. Living things grow and develop
During their lifetimes, living things grow, or increase in size.
Living things develop, or change, during their lifetimes.

6. Living things use energy and respond to stimuli
Organisms that convert light energy to usable energy are called autotrophs.
Heterotrophs are organisms that obtain energy from other organisms.
If an organism detects a change in its external environment, it will respond to that change.

7. What do living things need?
Food
Water
A place to live (habitat)

8. How are living things classified?
Scientists group organisms with similar traits and use a system to name them.
Binomial nomenclature is a naming system that gives each living thing a two-word scientific name.
The branch of science that classifies living things is called taxonomy.
A dichotomous key is a tool used to identify an organism based on its characteristics.
