Classifying Organisms - an Intro to Domains and Kingdoms
Transcript of Classifying Organisms - an Intro to Domains and Kingdoms
- Process of grouping organisms based on their structural similarities
- The study of classifying organisms is called taxonomy
- Classifying living organisms is Similar to the classification of produce in grocery stores
- scientists Classify organisms based on their similarities Domains and Kingdoms By heather van houten What is classification? What are the levels of classification? •Domain
-The more classification levels two
organisms share, the more similar
characteristics they have. the classification of owls - The top row has a wide range of organisms
- As you go down the classification system, there are fewer organisms in each level
- The fewer organisms there are, the more similar characteristics they have in common with owls. Three domains
under the domains:
Animals Bacteria - All around us, even inside our bodies
- Can be either heterotrophs or autotrophs
- Nucleus - dense part of the cell which contains nucleic acids.
- Nucleic acids - direct the cell's activities. Archaea - Can be found in harsh environments such as hot springs and swamps
- Name comes from Greek word "ancient" because they usually live in harsh environments
- unicellular prokaryotes
- Can be either heterotrophs or autotrophs - Structure and chemical make up really different from bacteria
- Classified in their own domains Eukarya - 4 different kingdoms of Eukarya - protists, fungi, plants, and animals Protists - Any eukaryotic organisms that cannot be classified as an animal, fungi, and plants
- Really special and different from other types
- Sometimes called "odds and ends."
- can be either heterotrophs or autotrophs, either multicellular or unicelluar. Fungi Plants Animals - Examples of Fungi - Mushrooms, molds, and mildew - MOst fungies multicellular, but the yeast you use for baking is unicellular
- Heterotrophs; most of them feed by absorbing nutrients from dead or decaying organisms - Multicellular
- Most of them live on land
- The plant kingdom varies
ex. both tall plants and small plants exist
some plants can reproduce, some of them can't - Familiar organisms like dogs and cats
- food and environment varies widely Aristotle How did it all begin? - The first person known to
classify living things scientifically
- Aristotle used two groups, animals
and plants, to group living things 384 BC -
322 BC Carolus Linnaeus - 2000 years later, Linnaeus
created a new classification system
- He grouped living things into 2 Kingdoms, Plants and Animals
-living things were classifyied by their structural similarities 1707 - 1778 Carl Woese - today our technology allows us to study living organisms more closely so we can be more specific with our classifications
- Woese placed all living things into one of three domains:
bacteria, archaea & eukarya
- each domain contains one or more kingdom
- there are 6 kingdoms of life for example... Let's look at how
biologists classify owls. Today we will
Kingdoms. You can look at it like this... Let's look at this panther. OK...On to Domains and Kingdoms. This is one way to look at it... Here's another way... and another... The thing about science is that it's always changing. The way we classify organisms has changed so much over time.
Why? As scientific equipment and technology (like microscopes) get better and become more accurate, they allow scientists to see and study organisms they didn't even know existed before! The more we know, the more accurate at classifying life we can be.
