Six Characteristics of Living Things
1. All living things are composed of cells.2. Complex organization patterns are found in all living
organisms.3. All organisms use energy.4. All organisms have stable internal conditions which
must be maintained in order to remain alive.5. All organisms grow and change.6. All organisms reproduce in order to continue the
species’ life.

1. All Living Things are Composed of Cells
Two types of cells:1. Prokaryotic Cells
Most are single- celled organisms
2. Eukaryotic Cells

• Metabolism: All of the chemical reactions that occur within an organism.– Catabolism: Breaks larger molecules down into
smaller molecules to produce energy (i.e., Cellular Respiration)
– Anabolism: Uses energy released by catabolic pathways to create cellular components (i.e., Photosynthesis)

4. All organisms have stable internal conditions which must be maintained in order to remain
alive. This is called homeostasis.

5. All organisms grow and change.
a. Changes occur during the life cycle of an organism.
b. Some changes are inherited, which over time are called __________.adaptations
