Taxonomy

“By the help of microscopes, there is nothing so small, as to escape our inquiry.”

– Robert Hooke

What is the broadest category in taxonomy and how do biologists classify organisms into this category?

Turn and Talk

What is the next category in taxonomy and how to biologists classify organisms into these categories?

What do all organisms in the Domain Eukarya have in common?

Taxonomy

• Taxonomy is the classification of life into categories.

• All organisms are grouped based on their similarities.

• Groups get more specific as you go down.

Taxonomy

Species

Domain

Kingdom

Phylum

Class

Order

Family

Genus

Basic Characteristics

• All organisms are placed into their categories based on some basic characteristics about them.

• Some examples include but are not limited to: prokaryotic or eukaryotic; unicellular or multi-cellular, autotrophic or heterotrophic, and asexual reproduction or sexual reproduction.

Prokaryotic vs. Eukaryotic

• Prokaryotic cells do not have a nucleus.

• Eukaryotic cells do have a nucleus that is surrounded by a membrane.

• This nucleus holds all the genetic information for the cell (the DNA).

Unicellular vs. Multi-cellular

• Unicellular organisms contain only one cell.

• Multi-cellular organisms are made of more than one cell.

Autotrophic vs. Heterotrophic

• Autotrophic organisms make their own food. (i.e. plants through photosynthesis)

• Heterotrophic organisms obtain energy/food by feeding on other organisms.

Asexual vs. Sexual

• Organisms that have asexual reproduction means that they receive all their genetic material from only one parent.

• Organisms that have sexual reproduction means that they receive their genetic material equally from two parents.

Domains

• When scientists classify organisms, they begin with the Domain.

• This is the most broad category of taxonomy.

• There are 3 Domains –Bacteria, Archaea, and Eukarya.

• In order to classify them into a Domain, scientists only look for one thing – a nucleus.

Domains and Kingdoms

Is there a nucleus, or not?

Domain - Bacteria

• All organisms in the Domain, Bacteria, are Prokaryotic.

• They do not have a nucleus.

Domain - Archaea

• All organisms in the Domain, Archaea, are Prokaryotic.

• They do not have a nucleus.

Domain - Eukarya

• All organisms in the Domain, Eukarya, are Eukaryotic.

• They do have a nucleus.

Kingdoms

• After classifying them into Domains, scientists then classify them further into Kingdoms depending on their basic characteristics.

• The Domain Bacteria has one Kingdom – Bacteria.

• The Domain Archaea has one Kingdom – Archaea.

• The Domain Eukarya has four Kingdoms – Protista, Fungi, Plantae, and Animalia.

Domains and Kingdoms

What are the other basic characteristics of this organism?

Kingdom - Bacteria

• Prokaryotic

• Unicellular

• Autotrophic or heterotrophic

• Asexual reproduction

EXAMPLE: Can cause sickness

Kingdom - Archaea

• Prokaryotic

• Unicellular

• Autotrophic or heterotrophic

• Asexual reproduction

EXAMPLE: Exists in extremeenvironments.

Kingdom - Protista

• Eukaryotic

• Most Unicellular and some simple multi-cellular organisms.

• Autotrophic and/or heterotrophic.

• Asexual and/or sexual reproduction.

EXAMPLE: Amoeba, molds, etc.

Kingdom - Fungi

• Eukaryotic

• Most multi-cellular, some unicellular

• Heterotrophic – receives nutrients from decomposing organic matter.

• Asexual or sexual reproduction

• Mushrooms and yeast

Kingdom - Plantae

• Eukaryotic

• Multi-cellular – has cell walls and chloroplasts for photosynthesis.

• Autotrophic – use photosynthesis to create own food.

• Asexual and/or sexual reproduction

Kingdom - Animalia

• Eukaryotic

• Multi-cellular – does not have cell walls or chloroplasts.

• Heterotrophic

• Sexual reproduction

“By the help of microscopes, there is nothing so small, as to escape our inquiry.”

Guided Practice

• You’re all going to have the opportunity to pretend that you’re biologists discovering new organisms!

• Your job is to classify the organisms into a Domain and Kingdom.

20 min

Everyone should take out 1 sheet of notebook paper.

Guided Practice

• I’m going to give you a series of organisms to classify.

• I won’t give you any information about these organisms.

• I will only answer the questions you ask about the organisms.

• You will work in your table groups.

• Your goal is to be the first team to correctly classify them.

20 min

Guided Practice

• How does this organism obtain nutrients?

• How does this organism reproduce?

• Does this organism have cells with a nucleus?

• Is this organism made of just one cell or many cells?

20 min

These are example questions you might ask to further your inquiry.

Take a second to write down some questions you think you might ask me.

Independent Practice

• To practice these vocabulary words, we’re going to play some cellular BINGO!

• Every has one BINGO card and markers.

• I will read descriptions for the words and you will use your knowledge to independentlyfind and mark the words on your BINGO card.
