Dichotomous Keys A key used to identify an object and gives two choices at each step.

What type of tree is this?

Let's make a dichotomous key!

DO NOW: What is this girl’s name? 1a. Sex female---2 1b. Sex male---5 2a. Hair color red---go to 5 2b. Hair color brown or blond--3 3a. Hair color blonde---Jane 3b. Hair color brown---4 4a. Glasses worn---Donna 4b. Glasses not worn---Linda 5a. Ponytail ---- go to 6 5b. No Ponytail ---go to 7 6a. Mole --- Sharon 6b. No Mole ---- Lucille

Let’s make a dichotomous key! Cut out the creatures and together we will give each a name.

a. b. 10. a.

DO NOW: What 2 groups could you put these organisms into?

The 5 Kingdoms: CLASSIFICATION Classifying living things helps us learn more about them. What is the most general way to classify living things? The 5 Kingdoms:

Classifying Living Things… Animal Living Non-Living Plant Fungi Monera Protist

How do we classify animals even further? Mammals Birds Animal Reptiles Living Non-Living Amphibians Plant Insects Fungi Fish Monera Protist

DO NOW: What do scientists base their classification on? Physical characteristics Mode of reproduction Number of cells Mode of nutrition

Types of Reproduction Sexual- 2 parents Asexual- 1 parent

Autotrophic Heterotrophic Types of Nutrition Autotrophs make their own food (producers), Heterotrophs obtain nutrition from other sources (consumers)

Venus fly trap: autotroph or heterotroph?

Venus fly trap: autotroph or heterotroph? Mixotroph! They still get their energy from the sun and transform it into food (such as sugars) using photosynthesis. They use the dead insects for their nutrients. We find the carnivorous plants in environments where there are very low levels of nutrients in the soil.

Number of Cells Unicellular Multicellular

MONERA (bacteria) Prokaryote Prokaryote: No true nucleus or other membrane bound organelles such as mitrochondria. Eukaryote: Membrane bound nucleus

The most general category used to classify living things is… DO NOW: The most general category used to classify living things is… Kingdom

The Five Kingdoms 1. Monera (Bacteria) No nucleus- prokaryote Unicellular Some Heterotrophic Some Autotrophic Asexual Reproduction

2. Protista Amoeba Euglena Nucleus Mostly Unicellular Some Heterotrophic Some Autotrophic Asexual Reproduction Examples: Paramecium Amoeba Euglena

Amoeba Pseudopods

Paramecium Cilia

Stentor cilia

Euglena flagellum flagellum

3. Fungi Nucleus Unicellular and Multicellular Heterotrophic Asexual and Sexual Reproduction Examples: Yeast, Foot fungus, Mold, Mushrooms

4. Plants Nucleus Multicellular Autotrophic Sexual Reproduction

DO NOW: What are the 5 Kingdoms? Monera Protist Fungi Plant Animal

Which Kingdom has no nucleus? MONERA (bacteria)

Which life process is classified as autotrophic in some organisms and heterotrophic in other organisms? hormonal regulation nutrition anaerobic respiration transport

Is this organism a heterotroph or an autotroph?

Why is the organism in the diagram considered a heterotroph rather than an autotroph? It makes its own food. It divides by mitosis. It transforms light energy into food. It absorbs food from the soil.
