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

14. a. b.
10. a.

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

16. 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:

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

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

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

20. Types of Reproduction
Sexual- 2 parents
Asexual- 1 parent

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

22. Venus fly trap: autotroph or heterotroph?

23. 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.

24. Number of Cells
Unicellular
Multicellular

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

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

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

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

29. Amoeba
Pseudopods

30. Paramecium
Cilia

31. Stentor
cilia

32. Euglena
flagellum
flagellum

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

34. 4. Plants
Nucleus
Multicellular
Autotrophic
Sexual Reproduction

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

36. Which Kingdom has no nucleus?
MONERA (bacteria)

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

38. Is this organism a heterotroph or an autotroph?

39. 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.
