1. Taxonomy

Taxonomy is science of classifying living things.

Two main purposes: Help identify organisms/represent relationships between organisms

2. What are the levels of Taxonomy?

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

3. What are the 3 Species Concepts?

• Morphological: look at the body shape/size/features

• Biological: two organisms can produce fertile off-spring

• Phylogenetic: look at the evalutionary history of organisms

What is Binomial nomenclature?

Used for naming organisms by two names referred to as the “Scientific Name”

What is Genus + Species?

Genus - first part of the name (Upper case)

Species - second part of the name (lower case)

Examples: Ursus horribilis — grizzily bear

The Domains of Life

• Bacteria

• Archaea

• Eukarya

These domains are separated generally by their cell type.

Diversity of Life

Scientists estimate there are over 2 billion specis on earth.

What are the Six Kingdoms?

Explain Kingdom Archaea

• Prokaryotic

• Asexual reproduction

• Oil wells

• Acidic mine drainage

• very salty conditions

Explain Kingdom Bacteria

• Prokaryotic

• Unicellular '

• Heterotrophs / Autotrophs

• Asexual reproduction

Explain Kingdom Protista

• Eukaryotic

• Unicellular / Multicellular

• Heterotrophs / Autotrophs

• Asexual / Sexual reproduction

• Plant like / Animal like / Fungi like

Major Cell Types

1. Prokaryotes

• “before the nucleus”

• simple single cell

• during reproduction, DNA comes in rings called plasmids

• no complex organelles

2. Eukaryotes

• “True nucleus”

•
