3. Biology What do you think that the word BIOLOGY means?
Write down your personal meaning in your notes
Let’s break the word apart:
“Bio-” means LIFE
“-ology” means THE STUDY OF
So, Biology is the study of life
What do I mean by “life”
The word “life” may conjure up different pictures in different peoples’ minds
Life means things that are plant, animal, protists, etc.
Life means things that are as old as a sequoia tree or as large as an elephant or as small as a paramecium

5. What are some things that ALL living things do?
Growth and Repair
Excretion
Nutrition
Transport
Synthesis
Respiration (cellular)
Regulation
Reproduction*
The Gentleman’s Pirate

6. 1- Growth and Repair
To increase in size or numbers

7. 2- Excretion To remove metabolic wastes
These are wastes that were CREATED by an organisms

8. 3- Nutrition Bringing in or making “food” DIGESTION
Breaking down into smaller pieces
Use nutrients that are obtained for other life processes. Such as:
Growth
Repair of injuries
Replacement of worn out cells/tissues

9. 4- Transport Absorption and Distribution of materials in an organism
YES! Memorize this!!! 
Moving of materials
Into and out of cells
Within a cell
Within an organism

10. 5- Synthesis To create To make To build
Combining smaller parts to make something larger and more useful
Used to make large proteins and complex sugars
“Making Cookies”

11. 6- Respiration NOT Breathing Gas exchange on a cellular level
Do trees breathe?
Gas exchange on a cellular level
Animals generally inhale oxygen and release carbon dioxide
Plants generally take in carbon dioxide and release oxygen
Why do we perform this gas exchange?
To get ENERGY (ATP) from nutrients
Energy is used by ALL cells
Occurs in the mitochondria

12. 7- Regulation Control and coordination of life processes
Example: What happens when you get hot?
Example: Thermostat
Single celled organisms
Performed by the nucleus
Multicellular organisms
Performed by nervous system or hormone or both

13. 8- Reproduction* To create a new offspring
Only life function NOT necessary for the life of an organism, but necessary for the life of a species
In other words, an ORGANISM doesn’t have to reproduce, but a SPECIES does

14. Metabolism What is Metabolism? NO! (Write this down)
Metabolism is NOT how fast you digest your food!
Metabolism is ALL of the functions necessary to sustain life
In other words, metabolism IS all of the 8 life functions
Metabolism is the Gentleman’s Pirate! 
So, in order to be considered alive, an organism must perform ALL 8 LIFE FUNCTIONS
Question: Is water alive?

15. Other Things
There are a few other things that living things do- even though they aren’t considered “life functions”
All living things will react in response to a stimulus
ie- Plants grow toward the light
You pull your arm away from pain
…Yawn…

16. Homeostasis
To maintain a stable internal environment despite external chances
Failure to maintain homeostasis will result in illness or death

17. Open your Workbook to p. 19 (1-18)
Respiration
They both perform the 8 Life Functions
I would test if it performs the 8 Life Functions.
