1. Topic: Classification
Aim: Describe the classification system we use today.
Do Now:
1. Take out your classification reading notes.
2. Complete Review Question 1at the end of yesterday’s notes.
3. Take out your numbers to use at the end of the period!
HW: Create a mnemonic device to help you remember the 7 levels of classification.

2. Determine the length of each cell in um.
250um + 125um
= 375um
Diameter = 1mm
= 1000um

3. Let’s think... How would you find a box of your favorite cereal in a grocery store that you have NEVER been before? Would it be easy to find? Be specific about the clues you would use to find the cereal.

4. 1. Define classification.
The process of dividing things into groups.
How can we classify our class????

5. Do you know who the first person that classified things was?
Artistotle

6. How did Aristotle classify living things
How did Aristotle classify living things? Animal Subgroups: Land, Water, Air Plant Subgroups: Small, Medium, Large

7. 2. Identify the branch of biology that is used for classifying and naming organisms.
Taxonomy

8. 3. Identify the groups taxonomists use to classify organisms.
Taxonomists arrange, or classify similar organisms into a group called a taxon.
How many taxons are found in this diagram?

9. 4. Identify or list the 7 levels of classification.
Kingdom
Phylum
Class
Order
Family
Genus
Species

10. 5. Describe the meaning of a very broad taxon.
It includes many different organisms.
Examples???
In broad daylight
A broad river

11. It contains the largest # of organisms.
6. Identify the largest and broadest taxon. Support your answer. (How do you know?)
Kingdom
It contains the largest # of organisms.

12. 7. Describe why the lowest level is most specific.
It only includes ONE TYPE OF ORGANISM.

13. It only includes one type of organism.
8. Identify the SMALLEST and most specific taxon. Support your answer.(How do you know?)
Species
It only includes one type of organism.

14. How similar are organism that share the same species????
Organisms in a species are SO SIMILAR that that can mate with each other & produce fertile offspring.

15. 9. Identify the types of names that were confusing to use.
Using common names was confusing and made communication about organisms difficult.

16. Identify the example of how common name are confusing to use discussed in the reading. Sea Horse It is not a horse. It is fish.

17. Sea horses range in size from 1. 5cm – 35cm
Sea horses range in size from 1.5cm – 35cm. Juveniles are exact replicas of adults at birth and are about 5mm-6mm in length. Males can receive up to 1500 eggs from the female and carry seahorse eggs for one month before they hatch.

18. 10. Explain why using taxonomy was a better method for naming organisms.
Using taxonomy makes it easier to communicate with each other about other organisms.

19. 11. Identify the language used in an early system of taxonomy.
Latin

20. 12. Describe the disadvantage (problem) of using Latin words to describe what organisms looked like.
Latin words were too long and hard to remember.
Scientists around the world often names the same organism using different Latin names.

21. The common briar rose Some scientists named it: Rosa sylvestris inodora seu canina “Odorless woodland dog rose” Other scientists called it: Rosa sylvestris alba cum rubore “Pinkish-white woodland rose with hairless leaves”

22. 13. Identify the inventor of the present system of taxonomy.
Carl Linnaeus

23. 14. Identify the current system of naming organisms.
Binomial nomenclature

24. Binomial nomenclature
the choosing of names for things, especially in a science or other discipline.
TWO
NAME

25. Before Linnaeus developed his naming system, plants and animals were named by a series of Latin words that described the physical appearance of the organism. This was very confusing. For example, let’s look at the first name of the honey bee.
Apis pubescens, thorace subgriseo, abdomine fusco, pedibus posticis glabris utrinque margine ciliatus.
This means “fuzzy bee, light gray middle, brown body, smooth hind legs that have a small bag edged with tiny hairs.” Linnaeus named it Apis mellifera which means “honey-bearing bee.”
