2. Unit Question/IB Trait
STATEMENT OF INQUIRY: Interactions among environments allows organisms to create their own identity and form relationships with various communities in order to survive.
IB TRAIT: COMMUNICATORS

3. 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.

4. Taxonomy
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species

5. 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.

6. 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).

7. Unicellular vs. Multi-cellular
Unicellular organisms contain only one cell.
Multi-cellular organisms are made of more than one cell.

8. Autotrophic vs. Heterotrophic
Autotrophic organisms make their own food. (i.e. plants through photosynthesis)
Heterotrophic organisms obtain energy/food by feeding on other organisms.

9. 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.

10. 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.

11. Is there a nucleus, or not?
Domains and Kingdoms
Is there a nucleus, or not?

12. Domain - Bacteria
All organisms in the Domain, Bacteria, are Prokaryotic.
They do not have a nucleus.

13. Domain - Archaea
All organisms in the Domain, Archaea, are Prokaryotic.
They do not have a nucleus.

14. Domain - Eukarya All organisms in the Domain, Eukarya, are Eukaryotic.
They do have a nucleus.

15. 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.

16. What are the other basic characteristics of this organism?
Domains and Kingdoms
What are the other basic characteristics of this organism?

17. Kingdom - Bacteria Prokaryotic Unicellular
Autotrophic or heterotrophic
Asexual reproduction
Can cause sickness

18. Kingdom - Archaea Prokaryotic Unicellular Autotrophic or heterotrophic
Asexual reproduction
EXAMPLE: Exists in extreme environments.

19. Kingdom - Protista Eukaryotic
Most Unicellular and some simple multi-cellular organisms.
Autotrophic and/or heterotrophic.
Asexual and/or sexual reproduction.
EXAMPLE: Amoeba, molds, etc.

20. Kingdom - Fungi Eukaryotic Most multi-cellular, some unicellular
Heterotrophic – receives nutrients from decomposing organic matter.
Asexual or sexual reproduction
Mushrooms and yeast

21. Kingdom - Plantae Eukaryotic
Multi-cellular – has cell walls and chloroplasts for photosynthesis.
Autotrophic – use photosynthesis to create own food.
Asexual and/or sexual reproduction

22. Kingdom - Animalia Eukaryotic
Multi-cellular – does not have cell walls or chloroplasts.
Heterotrophic
Sexual reproduction

23. Turn and Talk
What category comes after Domains? How do scientists classify organisms into this category?

24. Everyone should take out 1 sheet of notebook paper.
Guided Practice
20 min
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.
Everyone should take out 1 sheet of notebook paper.

25. Guided Practice
20 min
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.

26. Take a second to write down some questions you think you might ask me.
Guided Practice
20 min
These are example questions you might ask to further your inquiry.
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?
Take a second to write down some questions you think you might ask me.

27. Guided Practice Practice Round Archaea - Archaea

29. Independent Practice
35 min
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 independently find and mark the words on your BINGO card.

30. What do all organisms in the Domain Eukarya have in common?
Turn and Talk
What is the broadest category in taxonomy and how do biologists classify organisms into this category?
