Notes: Taxonomy – part 1

Taxonomy is the Science of __________________________________________.

Why do we need to classify known organisms?

Imagine: ______________________________________

How do you organize it? ______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Classification is a way to _______________________________, in order to easily see the relationship between organisms.

Classification organized things into __________________ based on ___________________________.

The following are considered when classifying organisms:

_______________________ structures: ________________________ Internal structures: _______________________ Cellular structure: ____________________________________________________ Number of Chromosomes DNA & ____________________ similarities Methods of obtaining ____________________________: ________________________________ Methods of Reproduction: ____________________& ___________________________ Embryology: _________________________________________________________

Phylogeny

Is the study of the ________________________________ history of an organism Based on the following: ___________________, DNA and embryology

Why do we need a standard why of naming organisms?

______________________________can be confusing Examples:

o ______________________ - Crotalus horridus

o Which one of these is NOT actually a bear? Panda bear, Koala bear, Black bear

o What type of organism is it (invertebrate, mammal, insect, fish, reptile, bird, ..)1. Sea Monkey - ____________________________2. Firefly - __________________________________3. Ringworm - ______________________________4. Jellyfish - ________________________________5. Spider monkey - __________________________________6. Crayfish - ______________________________________7. Sea Horse - ____________________________________

o Consider the following…1. Are all “Grey Wolves” gray? ___________________________________________2. Are all “Black Bears” black? ____________________________________________3. Which is more venomous – a water moccasin or a cottonmouth snake?

______________________________________________________________

Classification System

Developed by Carolus _______________________________, who used Greek and __________ names

He placed ALL organism into a few ____________________ groups:

o _____________________________________

Grouping

Each group gets _________ and more _____________

A. ____________________________________B. ____________________________________C. ____________________________________D. ____________________________________E. ____________________________________F. ____________________________________G. ____________________________________

OMG – How Am I Supposed to Remember The Order?

______________________________________________________________________________________

Scientific Names The Scientific name is always ________________________ + _______________________ What would the scientific name for humans be: ______________________________

Scientific name practice:

a) Tiger - ________________________________________________________b) Lion - ________________________________________________________c) Gray Wolf - ____________________________________________________d) Domestic Cat - _________________________________________________e) Mountain Lion - _______________________________________________

Which two have the closest relationship and why? _______________________________________________

Name: __________________________________

Notes: Taxonomy – Part 2

OH And One More Thing …

The system of naming is called ____________________________ __________________________________

Which means it is a _______ - name system: (_____________________ + _____________________)

Rules:

1. Names must either be underlined or italicized

2. __________________ capitalized, _________________ is lowercase

3. Can be Abbreviated. Ex: _____________________ and F. tigris

What is a species?

Defined as organisms that can __________________________________ with one another, and produce ____________________ offspring.

o Only members of the same ___________________ can interbreed under natural conditions.

When 2 organisms of _________________________ species interbreed, the offspring is called a _____________________.

Example: ____________________ and ___________________.

Quick Review:

1. Kingdom , _______________________, Class, Order, _______________________, Genus, _____________________.

2. Which two groups are used for an organism’s scientific name? ________________________________

3. Which of the following pairs is MOST closely related?

Acer rubrum & Acer saccharum

Acer rubrum & Chenopodium rubrum

4. The System we use for naming is called ___________________________ noomenclature.

5. The science of Classification is called___________________________________.

There are currently ____ Kingdoms

Kingdoms based on:

Number of ______________o ____cellular or ________cellular

How it obtains ________________________o Heterotrph or ________________________

____________________ of cellso ___________karyote or ________karyote

1. Heterotroph ________________________________________________________________________________________________________________________________________________

2. Autotroph ________________________________________________________________________________________________________________________________________________

3. Unicellular ________________________________________________________________________________________________________________________________________________

4. Multicellular ________________________________________________________________________________________________________________________________________________

5. Prokaryote ________________________________________________________________________________________________________________________________________________

6. Eukaryote ________________________________________________________________________________________________________________________________________________

What kinds of organisms are in each of the Kingdoms??

Use the chart below to fill in the details as we go through the next few slides

3 Domains of Life

__________ groups, called ________________, contain all _____ Kingdoms.

1. Domain ______________________________: includes organisms composed of ____________________________ cells (plants, animals, fungi, protists)

2. Domain ____________________________: includes all _______________________________ cells, Kingdom: ____________________________

3. Domain ____________________________: includes only ___________________ bacteria, Kingdom:___________________________________

Identifying Unknown Organisms

When Biologists do field studies, they often encounter ______ specimens that they would need to ______________________.

__________________________ often contain pictures for referencing organisms.

_____________________________________ Key

A step-by-step _________________ to help identify an organism.

Follow a series of _______________________ the lead to the organism’s _______________________.

1. Has green colored body ......go to 2 Has purple colored body ..... go to 4 2. Has 4 legs .....go to 3 Has 8 legs .......... Deerus octagis 3. Has a tail ........ Deerus pestis Does not have a tail ..... Deerus magnus 4. Has a pointy hump ...... Deerus humpisDoes not have a pointy hump.....go to 5 5. Has ears .........Deerus purplinis Does not have ears ......Deerus deafus
