TaxonomyTaxonomy - the scientific study of how things are classified.

Carolus Linnaeus developed the system we use today.

All organisms are given a two part name based on shared characteristics.

CANIS LUPUS

The first part of the organism’s scientific name is its genus.

Genus is a classification grouping that contains similar, closely related organisms.

CANIS LUPUS

The 2nd part is the Species

CANISLUPUS

Recall, species are organisms that can mate and produce offspring

Taxonomic Key

A series of paired statements that describe physical characteristics of different organisms

Seven Levels of Classification:

Archaebacteria

Unicellular organisms that already existed billions of years before the dinosaurs. Scientist’s think they were the earliest form of life.

Archaebacteria

Live in extreme environments and can survive where no other organisms can.

EubacteriaThese bacteria are constantly on & around us. Eubacteria use the sun’s energy to produce oxygen, helping keep the Earth’s oxygen at the proper level.

Reproduction of bacteria

Some bacteria go through asexual reproduction, while others go through a form of sexual reproduction known as conjugation.

Asexual Reproduction

Binary fissionthe cell duplicatesits genetic material and then divides with each cell gets exactly the same thing.

Obtaining FoodObtaining Food

Some bacteria are autotrophic autotrophic and make their own food the same way plants do. Others are heterotrophicheterotrophic which means they consume a variety of foods from milk to meat.
