DESCRIPTION

Classification and Taxonomy

Transcript

Bellringer: Monday, March 17, 2014

What is the name of this animal?

a. Puma

b. Cougar

c. Mountain lion

d. Panther

All of the above…these are

common names for the same

animal.

Objective

• We will define and recognize the importance of taxonomy

Anticipatory Set

What is the impact of having misleading names?

Anticipatory Set

To avoid confusion caused by regional names, biologists use a

classification system to group organisms in an organized and

logical manner and to assign names.

What is taxonomy?

•It’s the science of naming and classifying organisms.

What is Classification?

It’s the grouping of objects or information on the basis

of similarities.

The classification system:• Domain Dear

• Kingdom King

• Phylum Philip

• Class came

• Order over

• Family from

• Genus Great

• Species Spain

Hierarchical Classification

• Taxonomic categories• Kingdom includes all the

phyla

• Phylum includes all the classes

• Class includes all the orders

• Order includes all the families

• Family includes all the genera

• Genus includes all the species

• Species

Each level is

called a taxon

Human Classification• Domain Eukarya• Kingdom Animalia• Phylum Chordata• Class Mammalia• Order Primates• Family Hominidae• Genus Homo• Species sapiens

Work with your partner to create your own pneumonic for remembering the levels of classification:

• D

• K

• P

• C

• O

• F

• G

• S

Carl Linnaeus

• a.k.a. Father of Taxonomy

• Linnaeus developed the two-word naming system…binomial nomenclature.

Binomial Nomenclature

•Two-word naming system (scientific name)• Bi means 2/nomial means name

•Written in Latin•1st word represents Genus

• Written capitalized, underlined or Italicized•2nd word represents Species

• Written lower Case, underlined or Italicized

wolf

What are some ways these

animals are similar and what are

some ways they are different?

All belong to the same Kingdom: Animalia

Same phylum: Chordata

Same class: Mammalia

Same order: Carnivora

Dog, wolf, fox all belong to the same family: Canidae

Dog and wolf belong to same genus: Canis

Dog and wolf are different species

Dogs of different “breeds” all belong to the same species

Canis familiaris; therefore all can mate and produce fertile offspring.

According to the table, at what level does the domestic cat diverge from the ferret? (diverge means break away from)

Binomial Nomenclature

•Practice using binomial nomenclature by writing your first and last name correctly.

•Also, write the first and last name of 2 friends in class correctly.

Binomial Nomenclature

• Trade with the person next to you

• Grade their samples of their binomial nomenclature

• Provide feedback if they need more work

What would happen if there was not a taxonomic system for classifying organisms?

Explain your answer in complete sentences.

Bacteria

Bacteria

Objective

• We will identify and compare the characteristics of Kingdoms Archaebacteria and Eubacteria.

Domains and Kingdoms

BacteriaArchaea Eukarya

BacteriaArchae Protista Plantae Fungi Animalia

The three-domain system

The six-kingdom system

Vocabulary

1. Multicellular – many cells

2. Unicellular – one cell

3. Prokaryote- no nucleus

4. Eukaryote- has a nucleus

5. Autotroph – makes its own food

6. Heterotroph – consumes (takes in) food

7. Sexual – male and female make a different offspring

8. Asexual – not sexual, identical copy

9. Decomposer- breaks down dead stuff

10. Chitin- in cell wall of fungi

11. Motile - moves

12. Sessile – doesn’t move

Kingdom Archaebacteria

• The OLD bacteria

• Live in extreme habitats

• Unicellular

• Prokaryotic

• Heterotrophic and chemotrophic

• Asexual

Examples of Archaebacteria:

1. methanogens-produce methane: found in intestines and sewage plants

2. halophiles-love and live and salt

3. thermophiles-love and live in extreme temperatures

Kingdom Archaebacteria• Archaebacteria can live deep

in the ocean near geothermal vents called black smokers

• There is no light, so they carry out chemosynthesis instead of photosynthesis

Kingdom Eubacteria

• The NEW bacteria

• Live in a wide variety of habitats, including other organisms

• Unicellular

• Prokaryotic

• Heterotrophic, autotrophic, and chemotrophic

• Asexual

Examples of Eubacteria:

1. cyanobacteria-blue/green bacteria that chloroplasts evolved from

2. good bacteria-probiotics

3. bad bacteria-strep, staph, chlamydia

Guided practice- create a booklet

• Number each page at the bottom right corner (front and back)

• Create a cover for your 6 kingdoms booklet (pg 1)

• On page 2 do the following:• Write “Kingdom Archaebacteria” at the top• Include the characteristics from your chart for this kingdom

• Type of cell, feeding type, cell number, reproduction• Give a description and draw a picture for each example

• Methanogens, halophiles, thermophiles• Describe this kingdom in your own words

• On page 3 do the following:• Write “Kingdom Eubacteria” at the top• Include the characteristics from your chart for this kingdom

• Type of cell, feeding type, cell number, reproduction• Give a description and draw a picture for each example

• Cyanobacteria, good bacteria, bad bacteria• Describe this kingdom in your own words

Protists and Fungi

Protists and Fungi

Domains and Kingdoms

BacteriaArchaea Eukarya

Kingdom Protista

• The “leftover” group

• Similar to bacteria but are very complex

• Eukaryotic

• Mostly unicellular

• Autotrophic and heterotrophic

• Asexual

Examples of Protists:

1. ameobas (animal like): use psuedoposdia “fake feet” for movement. All aquatic

2. algae (plant like): the green stuff

3. slime molds (fungi like):

4. euglena (bacteria-like): use flagella and have an “eye”

Kingdom Fungi

• Eukaryotic

• Most are multicellular

• Heterotrophic (decomposers)

• Cell walls made of chitin

• Do NOT move. Live on or in their food.

• Nutrients absorbed after extracellular digestion

• Asexual• spores

Objective

• We will categorize organisms using a dichotomous key

What is a dichotomous key

• It is a tool used to determine the identity of an organism

• Usually asks yes or no questions

How do you use a Dichotomous Key

• Always gives you two choices

• Examine your organism and determine which of the 2 choices it fits the best

• Follow the steps

• Keep classifying until you get to the genus and species of the organism
