1 Classification

2 What are Dichotomous Keys? a method for determining the identity of something (like the name of a butterfly, a plant, a lichen, or a rock) by going through a series of choices that leads the user to the correct name of the item. A dichotomous key is a listing of characteristics, such as structure and behavior, organized in such a way that an organism can be identified or classified. Think of a dichotomous key as a type of scavenger hunt. Dichotomous means "divided in two parts".

3 Using a dichotomous key At each step of the process of using the key, the user is given two choices; each alternative leads to another question until the item is identified. 1a. If the leaves are flat.go to question 4. 1b. If the leaves are needle-like.go to question 2. 2a. Are the needles in a bunch? Go to question 5 2b. Are they spread along the branch? pine tree Eventually, when enough questions have been answered, the identity of the tree is revealed.

4 DICHOTOMOUS KEY EXAMPLE 1. a. tail fins are horizontal whale.go to 2 b. tail fins are vertical fish.go to 3 2. a. has teeth or tusk toothed whale..go to 4 b. has no teeth...baleen WHALE 3. a. has gill slits behind mouth shark....go to 5 b. has no gill slits..nonshark FISH 4. a. black with white underside.killer WHALE b. tusk, gray with dark spots...narwhal 5. a. head is hammershaped..hammerhead SHARK b. tail is half the body length.thresher SHARK

5 MAKING A DICHOTOMOUS CLASSIFICATION KEY

6

7 POSSIBLE DERIVED CHARACTERS Hammer-like head All made of one material Is it hinged Has a sharp edge Has holes

8 Hammer-like head NO Hammer-like head

9 Hammer-like head NO Hammer-like head

10 Hammer-like head NO Hammer-like head ALL Made of Wood NOT ALL Made of Wood

11 Hammer-like head NO Hammer-like head Sides of head are different Sides of head NOT different

12 Hammer-like head NO Hammer-like head Sides of head are different Sides of head are NOT different All wooden NOT all wooden

13 Hammer-like head NO Hammer-like head Sides of head are different Sides of head are NOT different All wooden NOT all wooden??

14 Engage Activity Create your own dichotomous key Create a dichotomous key to identify 2 people in this classroom, using questions based on gender, hair length/color, glasses (or not), clothing color, etc. 1a. Is this person male? Go to question 2. 1b. Is this person female? Go to question 3.

15 A Growing System New organisms are still being found that may not fit into existing categories. Taxonomists may create a new phylum for these organisms. Ex: Symbion Pandora (organisms that live on lobster lips)

16 Grouping of Organisms The grouping of organisms into kingdoms is based on 3 factors Cell Type (prokaryotic / eukaryotic) Cell Number (unicellular / multicellular Feeding Type ( autotroph / heterotroph)

17 Cell Type Prokaryotes Bacteria DO NOT HAVE: An organized nucleus Structured organelles Eukaryotes DO HAVE: Nucleus organized with a membrane other organelles

18 Cell Number Unicellular- single celled organism protozoans, bacteria, some algae Multicellular- many celled organism cells start to specialize/differentiate

19 Feeding Type How the organisms get their food Autotroph (Producer) Make their own food Heterotroph (Consumer) Must eat other organisms to survive Includes decomposers those that eat dead matter!

20 The Six Kingdoms Archaebacteria Eubacteria Protista Fungi Plantae Animalia Prokaryotes Eukaryotes

21 Kingdom Cell Type Cell # Feeding Type Archaebacteria Prokaryote Unicellular Autotroph Eubacteria Prokaryote Unicellular Both Protista Eukaryote Most Unicellular Both Fungi Eukaryote both Heterotroph Plantae Eukaryote Multicellular Autotroph Animalia Eukaryote Multicellular Heterotroph

22 Kingdoms of Bacteria Archaebacteria Ancient bacteria- Live in very harsh or extreme environments Extremophiles

23 Kingdoms of Bacteria Eubacteria Contains all prokaryotes except archaebacteria Live in soil, water, and even the human body! Live in more neutral conditions

24 Kingdom Protista Kingdom of mostly one celled eukaryotic organisms that are different from plants, animals, bacteria, and fungi Animal like: Protozoans Plant like: Algae Fungus like: Slime molds, water molds Often referred to the odds and ends kingdom

25 Kingdom Fungi Kingdom made up of: non green eukaryotic organisms no means of movement, reproduce by using spores, obtain food by breaking down substances in their surroundings and absorbing nutrients Includes some of the most important organisms

26 Kingdom Plantae Kingdom made up of: complex multicellular organisms usually green have cell walls made of cellulose cannot move around use the sun s energy to make sugar by photosynthesis Most animals are dependent on plants for energy and nutrients Autotrophs or Producers

27 Kingdom Plantae Plants also provide a habitat for many organisms Ex: homes for many birds and insects

28 Kingdom Animalia Kingdom made up of: Complex multicellular organisms lack cell walls usually move around quickly respond to their environment Capable of movement at some point in their lives Heterotrophs- depend on organisms from other kingdoms
