17. Can I?
Can I use a dichotomous key to identify an unknown organism? TOC # 18 Dichotomous key and Branching diagram Notes

18. What is a Dichotomous Key?
Definition
A dichotomous key is a tool that uses a series of paired statements to help someone identify the name of an organism when they are looking at the organism’s features. Purpose The purpose of the key is to name a creature. Sounds Like “Di-” means two. “Dichotomous” means divided into two parts.
Objective: Can I use a dichotomous key to identify an unknown organism?

19. How to work a Dichotomous Key
Step 1: Select the organism (Hint: look at this organism the entire time you are answering questions/ statements).
Step 2: ALWAYS start at the first set of questions/ statements (1a and 1b).
Step 3: Once you answer the questions/ statements, follow the directions to the next set of questions/ statements.
Step 4: Continue answering statements until you reach a name. This is the scientific name. It should be a 2 part name: Genus species.
Step 5: Select the next organism and repeat
steps 2-4.
Objective: Can I use a dichotomous key to identify an unknown organism?

21. Group Practice Fungus Classification Key
1 a. Grows shelf-like on woon go to 2
b. Grows on a stem out of the ground go to 3
2 a. Pattern of semi-circular stripes turkey tail
b. No pattern of stripes or dots beefsteak
3 a. Has a round cap fly agraric
b. Has an irregularl shaped cap go to 4
4 a. Cap is funnel-shaped golden chanterelle
b.Cap is brain shaped common morel
Based on the key above, which fungus is shown?
A.turkey tail B.beefsteak
C.golden chanterelle D.common morel
Objective: Can I use a dichotomous key to identify an unknown organism?

22. Create a Dichotomous Key
Now you will create a dichotomous key in your group. Every group member will work on the same idea, but every individual needs their own written key. You will assign each school supply a different “code name.” One group member should write code names on a separate sheet of paper. Example: A pencil might be called whatyacallit in your group. At the end, make sure that your key makes sense by going through the steps for each school supply and seeing that your item matches your code name. If you have remaining time, try to incorporate additional school supplies that you have with you into your key.
Objective: Can I use a dichotomous key to identify an unknown organism?

23. What is a Branching Diagram?
Definition
A branching diagram is a diagram that shows the relationships among biological species based upon similarities and differences in the physical and/or genetic characteristics.
Purpose
The purpose of a branching diagram is to examine the relationship and common characteristics between organisms.
