Response to Stimulus

React to change

Maintain homeostatis

Page 5: It’s ALIVE!!!  Or, is it?

Reproduction

Ability to produce offspring

Asexual ReproductionONE parent

Sexual ReproductionTWO parents

Page 6: It’s ALIVE!!!  Or, is it?

DNA/”Life Molecule”

DeoxyriboNucleic Acid

Passes on hereditary information

Page 7: It’s ALIVE!!!  Or, is it?

Use Σ

Organisms take in and use energy

MetabolismSum of all chemical reactions

YOU are walking, talking, living, breathing CHEMICAL REACTIONS!

Page 8: It’s ALIVE!!!  Or, is it?

Types of Σ

Page 9: It’s ALIVE!!!  Or, is it?

Chemicals of life

CarbohydratesSugar/Σ

LipidsFat/storage for Σ

ProteinsSome Σ/ made of amino acids

Nucleic AcidsDNA & RNA

Page 10: It’s ALIVE!!!  Or, is it?

One sentence to rule them all.

Nucleic acids provide the information to make proteins, which are then used to break down carbohydrates and lipids to release energy.

Grow & Develop

GrowGet bigger

DevelopΔ form

Necessities of lifeFood

Make it (producer/autotroph)Get it (consumer/heterotroph)OTHER (decomposer)

WaterAllows metabolism to take place

AirCO2 and O2

ShelterRest & security

Proof of LIFE

Back in the day…spontaneous generation

2 experiments prove LIFE from LIFE

Page 14: It’s ALIVE!!!  Or, is it?

Redi…an Italian doc (1600’s)

Fly babies only came from flies!!!!

Page 15: It’s ALIVE!!!  Or, is it?

Pasteur…a Frenchman (1800’s)

The air also let in bacteria.

LIFE from LIFE!!!

Page 16: It’s ALIVE!!!  Or, is it?

How life is organized…

ClassificationHOW we arrange/group organisms based on similarities

EIGHT levelsDomain

TaxonomyTHE Science of identifying & labeling/naming organisms

Carolus Linnaeus (Swedish botanist 1750s)Binomial Nomenclature

2 name systemGenus & Species

FIRST letter of Genus is CAPITALfirst letter of species is lowercaseBOTH are ALWAYS italicized or underlined

Classification of ALL Life!

Unicellular, Prokaryotic, Auto & Heterotrophs

Unicellular, Prokaryotic, Auto & Hetero

Dichotomous Keys

A tool that helps its user identify natural objects.

Dichotomous means "divided into two parts.”

Each step has TWO choices
