2. Living Things are Made Up of Cells1
Living Things are Made Up of Cells
Cells perform all of life’s activities:
METABOLISM

3. Living Things Respond to their Environment2
Transport – substances enter and leave cells
Excretion – removal of harmful wastes from the organism
Synthesis – building large molecules from small molecules

4. Living Things Obtain and Use Materials and Energy3
Living Things Obtain and Use Materials and Energy
Ex: All living things (like a salamander) must take in materials and energy to grow, develop and reproduce
Nutrition
Cellular Respiration

5. Living Things Maintain a Stable Internal Environment4
Ex: A human, running in a track meet, may have to deal with outside temperatures of 100ºF.
However, her internal temperature must remain stable.
HOMEOSTASIS

10. Taken as a Group, Living Things Change Over Time8
Taken as a Group, Living Things Change Over Time
The basic traits of an INDIVIDUAL organism usually do not change
-BUT-
Over many generations, GROUPS of organisms evolve (change over time)
