Warm-up
• On the next left side of your IntNB, answer the
following question in 3-5 sentences:
– What makes something alive?
Six Characteristics of Living Things
1.
2.
3.
4.
5.
6.
Composed of cells.
Complex organization patterns
Use energy.
Have stable internal conditions.
grow and change.
reproduce
1. All Living Things are Composed of Cells
Two types of cells:
1. Prokaryotic Cells
Most are singlecelled organisms
2. Eukaryotic Cells

2. Complex Organization Patterns
• Atomic Level
• Molecular Level
• Organelle Level/
Cellular Level
• Tissue Level
• Organ Level
2. Complex Organization Patterns
• Organism Level
• Population Level
– Group of same species
• Community Level
– Groups of different
species
• Ecosystem Level
– Living and non-living
elements
• Biosphere Level

Which level of organization is represented here?
Sunlight use Energy
3. All Organisms
Ecosystem
Producers
(plants and other
photosynthetic
organisms)
Heat
Chemical
Energy
Consumers
(including animals)
Heat
3. All Organisms use Energy
• Metabolism: All of the chemical reactions
that occur within an organism.
– Catabolism: Breaks down larger molecules into to
make energy (i.e., Cellular Respiration)
– Anabolism: Uses energy to create larger
molecules in cells (i.e., Photosynthesis)

4. All organisms have stable internal conditions which
must be maintained in order to remain alive. This is
called homeostasis.
Brrr….
Shiver…
I am so
cold!

b. Some changes
are inherited,
which over time
are called
__________.
adaptations
5a. Changes occur during an
organism’s lifetime
• Differentiation:
The process by
which cells
become
increasingly
different and
specialized
