1 6 Kingdoms of Life SOL BIO: 5 a-f

2 The student will investigate and understand life functions of archaebacteria, monerans (eubacteria), protists, fungi, plants, and animals including humans. Key concepts include: how their structures and functions vary between and within the kingdoms; comparison of their metabolic activities; analyses of their responses to the environment; maintenance of homeostasis; human health issues, human anatomy, body systems, and life functions; and how viruses compare with organisms.

3 As living things are constantly being investigated, new attributes are revealed that affect how organisms are placed in a standard classification system.

4 The grouping of organisms into kingdoms is based on 3 factors: –1. Cell Type –2. Cell Number –3. Feeding Type

5 1. Cell Type- The presence or absence of cellular structures such as the nucleus, mitochondria, or a cell wall Prokaryotes & Eukaryotes

6 Prokaryotes DO NOT HAVE: a membrane bound nucleus any membrane bound organelles

7 Prokaryotes DO HAVE: DNA Ribosomes Cytoplasm Cell membrane


9 Eukaryotes DO HAVE: separate membrane bound nucleus other organelles


11 2. Cell # - Whether the organisms exist as single cells or as many cells Unicellular- single celled organism Multicellular- many celled organism

12 UnicellularMulticellular

13 3. Feeding Type - How the organisms get their food –Autotroph or Producer Makes it’s own food –Heterotroph or Consumer Must eat other organisms to survive

14 There used to be only 5 kingdoms 1.Monera 2.Protista 3.Fungi 4.Plantae 5.Animalia This kingdom has now been divided into 2 – archaebacteria & eubacteria

15 6 Kingdoms Archaebacteria Eubacteria Protista Fungi Plantae Animalia Prokaryotes Eukaryotes

17 Archaebacteria Ancient bacteria- –Live in very harsh environments –Extremophiles –Methanogens –Halophiles –thermoacidophiles

18 Eubacteria It is the eubacteria that most people are talking about when they say bacteria, because they live in more neutral conditions. Cell walls have peptidoglycan

19 Bacteria Bacteria are unicellular prokaryotes

20 Bacterial Shapes Bacteria come in 3 main shapes –Rod or Stick (bacilli) –Sphere (cocci) –Helical or spiral (spirilla or borrelia)

21 Bacterial Locomotion Some bacteria have flagella or cilia for movement Some secrete a slime layer and ooze over surfaces like slugs

22 Bacterial Nutrition Some bacteria are autotrophs and can photosynthesize Some bacteria are heterotrophs

23 Protists Protists include many widely ranging microbes, including slime molds, protozoa and primitive algae. Odds & Ends Kingdom

24 Protists There are animal-like, fungus-like, and plant-like protists Some are beneficial Some protists can cause diseases in humans, such as:

25 DiseaseProtistVector (carrier) SymptomsDetails Amebic dysentery Ameba histolytica waterdiarrheacan get from tap water in some places Giardaisis (beaver fever) Giardiawaterdiarrhea, vomiting don't drink water from streams African Sleeping Sickness Trypanosoma Tse tse flyuncontrolled sleepiness, confusion Only found in isolated areas lives in blood Malaria PlasmodiumAnopheles mosquito fever, chills, death can be treated with quinine lives in blood results in millions deaths per year ToxoplasmosisToxoplasmacatsfetal death or brain damage pregnant women should avoid cat litter

26 Protists Disease Amebic dysentery Ameba histolytica

27 Protists Disease Giardiasis (beaver fever) Giardia

28 Protists Disease African Sleeping Sickness Trypanosoma

29 Protists Disease Malaria Plasmodium

30 Protists Disease Toxoplasmosis Toxoplasma

31 Protists Locomotion 3 types of movement: –Pseudopod (false foot) –Flagella/cilia –Contractile vacuoles

32 Protists Nutrition Protists can be autotrophs or heterotrophs

33 Fungi The Kingdom Fungi includes some of the most important organisms. By breaking down dead organic material, they continue the cycle of nutrients through ecosystems.

34 Fungi All fungi are eukaryotic They may be unicellular or multicellular All fungi have a cell wall, most Made of chitin Unicellular (yeast) Multicellular

35 Fungi Fungi can be very helpful and delicious Many antibacterial drugs are derived from fungi (for example, Penicillin) Penicillin

36 Fungi Fungi also causes a number of plant and animal diseases: Athlete's Foot

37 Fungi Ringworm

38 Fungi Locomotion Fungi are stationary They have root-like structures that they use for attachment

39 Fungi Nutrition All fungi are heterotrophs They absorb nutrients from dead organic matter They are saprophytes

40 There are 4 main types of Fungi (classified by how they reproduce) 1.Zygospore (Zygosporangia) Bread molds

41 There are 4 main types of Fungi 2. Club (Basidiomycetes) Mushrooms & puffballs

42 There are 4 main types of Fungi 3.Sac (Ascomycetes) Yeasts

43 There are 4 main types of Fungi 4.Imperfect (Deuteromycetes) penicillin

44 Plants All plants are multicellular autotrophs that have a cell wall made Of cellulose

45 4 important plant groups are the: Mosses- (Bryophytes) Ferns- Vascular, No seeds (Tracheophytes) Conifers- (Gymnosperms) Flowering Plants- Vascular, Seeds surrounded by fruit (Angiosperms) Non-vascular Vascular, Cone seeds

46 Nonvascular Plants Bryophytes Nonvascular plants are the simplest of all land dwelling plants. They lack an internal means for water transportation. They do not produce seeds or flowers. They generally only reach a height of 1 to 2 centimeters, because they lack the woody tissue necessary for support.

47 Mosses

48 Liverworts & Hornworts

49 Vascular Plants Tracheophytes Vascular plants have water-carrying tissues (xylem) and sugar-carrying tissues (phloem) enabling the plants to evolve to a larger size. Some vascular plants do not produce seeds. For example, ferns. Some vascular plants produce cone seeds (gymnosperms), some produce seeds surrounded by fruit (angiosperms).

50 Ferns- seedless vascular

51 Conifers (cone bearing) –Gymnosperms Oldest vascular plants

52 Flowering plants –Angiosperms –Seeds surrounded by a fruit.

53 Animalia All animals are multicellular heterotrophs that LACK a cell wall and are capable of movement at some point in their lives.

54 Asymmetrical – Asymmetrical animals (sponges) have no general body plan or axis of symmetry that divides the body into mirror-image halves. Animals are divided into taxa by many variables. One variable is body symmetry

55 Radial – Radially symmetrical animals (such as coral and jelly fish) have body parts organized about a central axis and tend to be cylindrical in shape.

56 Bilateral – Bilaterally symmetrical animals (such as humans and fish) have only a single plane of symmetry that produces mirror halves.


58 Animals are also classified by their skeletal system –Invertebrates have a hard external skeleton made of chitin known as an exoskeleton –Vertebrates have a hard internal skeleton made of bone

59 Some important animal groups (phyla) are the:

60 Porifera: sponges

61 Cnidarians: Jellyfish, corals, and other stingers... Their stinger is called a nematocyst

62 Nematocyst

63 Mollusks –Octopi, squid

64 Mollusks –Clams, oysters

65 Mollusks –Snails, slugs

66 Platyhelminthes (flat worms) –Tapeworms & flukes Human liver fluke

67 Annelids (segmented worms) –Worms & leeches

68 Echinoderms –Starfish, sea urchins, sea cucumbers

69 Arthropods –Shell fish, arachnids & insects!

70 Chordates –The Chordata is the animal phylum with which everyone is most familiar, since it includes humans and other vertebrates. –Nerve cord with swelling at one end (brain) –Internal skeleton –Elaborate organ systems

71 Chordates

72 Fish Aquatic, breathe with gills, ectothermic (cold-blooded), have scales Jawless fish- lack true teeth and jaws, ex. Lampreys Chondrichthyes- cartilage skeleton, ex. Sharks and rays Osteichthyes- bone skeleton ex. Goldfish, salmon

73 Amphibians & Reptiles Amphibians- lay eggs in water and live in water as larva (breath with gills), live on land as adults (breath with lungs), moist skin with no scales or claws, ectothermic Ex. Frogs and salamanders Reptiles- lay eggs on land, breath air with lungs, have dry skin with scales, ectothermic Ex. Lizards, snakes, crocodiles, turtles

74 Birds Have wings and feathers Lay eggs with hard shells Endothermic (warm-blooded) 4-chambered heart Ex. Eagle, chicken, ostrich

75 Mammals Breathe air with lungs Endothermic (warm-blooded) 4-chambered heart Most bear live young Nurse their young with milk Have hair or fur Ex. Humans, tigers, dolphins, elephants, bats

76 Viruses Viruses do not share many of the characteristics of living organisms. HIV Virus

77 Viruses Viruses are not cells. Basic viral structure consists of a nucleic acid (DNA or RNA) core surrounded by a protein coat. DNA or RNA

78 Viruses Viruses can reproduce only inside a living cell, the host cell.

79 Viruses The viral reproductive process includes the following steps: 1.A virus must insert its genetic material into the host cell. 2.The viral genetic material takes control of the host cell and uses it to produce viruses. 3.The newly formed viruses are released from the host cell.

80 Virus Vectors Viruses are transmitted through vectors, such as: Airborne –Influenza –Common cold

81 Virus Vectors Contaminated food or water –Hepatitis

82 Virus Vectors Infected animal bite –West Nile –Rabies –Avian influenza (bird flu) –Ebola

83 Virus Vectors Sexual contact –HIV –Herpes

84 Virus Vectors Contaminated blood products or needles –HIV –Hepatitis

85 Virus Treatment –Viruses cannot be treated with antibiotics. –There are some anti-viral drugs available. –You generally have to wait for the virus to run its course and let your immune system fight it off.
