5. A Swedish scientist that founded the science of taxonomy.
Carolus Linnaeus
A Swedish scientist that founded the science of taxonomy.

6. Is the science of naming and classifying organisms.
Taxonomy
Is the science of naming and classifying organisms.

7. Why do scientists classify living things?
To make it easier to organize, find, and share information and eliminate confusion.

8. Classification
The division of organisms into groups, or classes, based on their characteristics.

9. Classifying
The more levels shared, the more organisms have in common.
As you move down, there are fewer kinds of organisms in each group, but organism look similar and have more in common with one another.

10. How do scientists group living things?
Similarities
Differences
Characteristics
Levels

11. Scientists around the world use the system of binomial nomenclature to identify all living organism. This system assigns the Latin words as the scientific name.

12. Scientific name
The system that assigns the Latin words genus (capitalized) and species (lowercase)

13. Con’t
The first part of an organism’s scientific name is Genus and the second part is Species.
Together these two names identify one kinds of organism.
House Cat genus: Felis
Species: domesticus

14. Human Homo sapien
African Elephant Loxdonta africana
Mountain lion Felis concolor

15. Binomial nomenclature
the system of assigning two-part Latin or Latinized scientific names to plants, animals, and microorganisms, with the first word denoting the genus and the second the species.

16. Kingdom classification

17. For a long time, all life on Earth was divided into five kingdoms
For a long time, all life on Earth was divided into five kingdoms. Now many scientists say there are six kingdoms. They have divided the first kingdom into two separate groups.

18. Every living thing is classified into one of six kingdoms.
The kingdom is the largest group and is broken down into different groups that helps us to identify an animal.
Let’s look at these groups.

19. Levels of Classification
Kingdom
Phylum
Class
Order
Family
Genus
Species

21. Make a sentence to help you remember the groups in order.
K-king
P-Phillip
C-came
O-over
F-for
G-great
S-spaghetti

22. Largest group or level of classification
Kingdom
Largest group or level of classification
Organized according to certain traits

23. The Six Kingdoms

24. Archaebacteria( ancient )
Has one cell/prokaryotic
Has no nucleus
Makes its own food/autotroph
They do not have cell walls
The term archae means ancient
Some move from place to place
Lives in extreme environments (hot, cold, salty and acidic)

25. Autotroph
able to manufacture nutrients: describes organisms, especially green plants, that are capable of making nutrients from inorganic materials.

26. Types of archeabacteria
Methanogens- Produce methane and die if exposed to oxygen.
Halophiles- live in very salty lakes and ponds.
Thermophiles- live in extreme heat or cold.

27. Halophiles/thermophiles
A boiling hot springs in Yellowstone National Park. The orange-red coloration is caused by dense colonies of photosynthetic cyanobacteria

28. Eubacteria (true) Has one cell/prokaryotic Has no nucleus
Makes or obtains own food(can be considered heterotrophic or autotrophic)
Live in neutral conditions
Some move from place to place
Contains all prokaryotic cells except archaebacteria
Known as decomposers
They may be helpful or harmful

29. Heterotroph
getting nutrients through food digestion: obtaining nourishment by digesting plant or animal matter, as animals do, as opposed to photosynthesizing food, as plants do

30. E. coli

31. How do scientists classify organisms?

32. What do scientist use to name organisms?
Entrance question

33. Mostly one-celled eukaryotic organisms Makes or obtains own food
Protista Kingdom
Mostly one-celled eukaryotic organisms
Makes or obtains own food
Classified by the way they obtain energy
Some move from place to place

35. Protozoa

36. Paramecium/uses cilia for movement

37. Cilia
microscopic hairlike process extending from the surface of a cell or unicellular organism.

38. Contractile vacuole
membrane-bound organelle found in certain protists that periodically expands, filling with water, and then contracts, expelling its contents to the cell exterior.

39. Euglena/uses flagella for movement

40. Flagella
A long, threadlike appendage, especially a whip-like extension of certain cells or unicellular organisms that functions as an organ of locomotion.

41. Amoeba/uses pseudopods for movement

42. Pseudopods
A temporary foot-like extension of a one-celled organism used for moving about and for surrounding and taking in food.

43. Protists The three groups of protists are: Fungus –like Plant-like
Animal-like

44. Algae

45. Fungi
They are eukaryotic heterotrophs that can act as decomposers. The kingdom includes mushrooms, mold, and yeasts. All fungi except yeast are multicellular. Fungi obtain energy by absorbing materials. Fungi have no chloroplasts, but do have cell walls.

46. Fungus Kingdom Has one or many cells Has a nucleus/eukaryotic
Absorbs food/heterotroph
Cannot move from place to place sessile
Do not have chloroplasts or cell walls
Reproduce by spores

47. Spore
asexual reproductive structure: a small, usually one-celled reproductive structure produced by seedless plants, algae, fungi, and some protozoans that is capable of developing into a new organism.

48. Spores

49. Examples of fungi are mushrooms, molds and yeast.

50. It is used in Hindu rituals this mushroom could cause hallucinations.
Liberty cap grown in the UK

51. Slime mold

52. Mold
Molds

53. small single-celled fungus: a small single-celled fungus that ferments sugars and other carbohydrates and reproduces by budding. Genus Saccharomyces.
Yeast

54. Plant Kingdom Has many cells/multicellular Has a nucleus/eukaryotic
Makes its own food using chloroplasts /autotrophic
Has a cell wall made of cellulose
Cannot move from place to place/sessile

55. Cellulose
A stringy, fibrous substance that forms the main material in the cell walls of plants.

58. Plant kingdom
Plants are multicellular eukaryotic organisms that primarily produce their own food through photosynthesis.
Let’s look at how they obtain their food and energy.

59. Autotroph
able to manufacture nutrients: describes organisms, especially green plants, that are capable of making nutrients from inorganic materials.

60. Photosynthesis
carbohydrate production using light and chlorophyll: a process by which green plants and other organisms turn carbon dioxide and water into carbohydrates and oxygen, using light energy trapped by chlorophyll.

61. Producers
organism that makes its food: an organism that manufactures its own food from simple inorganic substances, e.g. a green plant
They are plants.

62. Animal Kingdom Has many cells/multicellular Has a nucleus/eukaryotic
Does not make own food/heterotrophic
Moves from place to place/highly mobile
Has a advance nervous system to respond to the environment
Reproduce sexually or asexually
Interdependent on other organisms/consumers

64. Consumers
organism that feeds on others: include herbivorous and carnivorous animals, which feed on plants and other animals respectively, and also organisms such as worms, fungi, and bacteria, which feed on nonliving organic material.

65. Heterotroph
getting nutrients through food digestion: obtaining nourishment by digesting plant or animal matter, as animals do, as opposed to photosynthesizing food, as plants do

66. Summary Classifying organisms helps in three ways.
1. Allows scientists to keep track of organisms
2. Helps people communicate by using one naming system
3. helps to organize information for further study.

67. Exit question
Name the 6 kingdoms.
