Overview of the Six Kingdoms
HOMEWORK Complete taking notes-see 2014 Classwork Complete worksheet (How are Plants Classified?) Georgia Science USERNAME: 5classdekalb PASSWORD: dekalbstudent5
2
Vocabulary Which term means one-celled? Many-celled? multicellular
unicellular Which term means that the organism produces its own food? Consumes food? autotroph heterotroph
3
Vocabulary Prokaryotic – describes an organism with cells that have a cell membrane but do NOT have a nuclear membrane Eukaryotic – describes an organism with cells that have a cell membrane and a nuclear membrane
4
Vocabulary Autotrophic – makes its own food
Heterotrophic – gets nutrients from the food it consumes
5
List of the Three Domains and the Six Kingdoms
1. Domain Bacteria Kingdom Eubacteria 2. Domain Archaea Kingdom Archaebacteria 3. Domain Eukarya Kingdom Protista Kingdom Fungi Kingdom Plantae Kingdom Animalia
6
The grouping of organisms into KINGDOMS is based on 3 factors:
1. Cell Type 2. Cell Number 3. Feeding Type
7
Prokaryotes or Eukaryotes
1st Criterion for Kingdom Divisions: Cell Type Prokaryotes or Eukaryotes
8
Prokaryotes Eukaryotes 6 kingdoms Eubacteria Archaebacteria Protista
Fungi Plantae Animalia Prokaryotes Eukaryotes
9
2nd Criterion for Kingdom Divisions: Cell Number
Unicellular- single celled organism – protozoans, bacteria, some algae Multicellular- many celled organism – cells start to specialize/differentiate
10
Unicellular Multicellular
11
3rd Criteria for Kingdom Divisions: Feeding Type
Autotroph or Producer Make their own energy source Heterotroph or Consumer Must eat other organisms to survive Includes decomposers – those that eat dead matter!
12
Kingdom Eubacteria Bacteria can live in many places on earth, inhabiting a wide variety of habitats, including other organisms Unicellular Prokaryotic Autotrophic or heterotrophic Thick cells walls
13
Kingdom Eubacteria Bacteria come in different shapes, such as round, spiral and rod-shaped.
14
Kingdom Eubacteria Bacteria can cause a wide variety of diseases, such as strep throat, food poisoning and the Black Death (bubonic plague of the Middle Ages)
15
Kingdom Archaebacteria
Bacteria that live in extreme habitats, such as hot springs, geysers, volcanic hot pools, brine pools Unicellular Prokaryotic Autotrophic or heterotrophic
16
Characteristics-Shapes
Cocci- round Bacilli- rod-shaped Spirilla- spiral
17
Kingdom Protista Extremely diverse group Eukaryotic
Most unicellular, some multicellular Autotrophic and heterotrophic Cells transforms food into energy
18
Are organisms with nuclei in their cells that do not fit into the fungi, plant, or animal kingdoms but may have characteristics of each.
19
Protozoa Animal-like protist First animals
They share some characteristics with animals. Can’t make their own food Take food from surroundings. Move through environment (slip and slide like jelly, use tail-like or fine hairs) Live wherever there is water Found in moist soil and inside other organisms
20
Kingdom Protista Euglena - autotrophic Volvox – a colonial protist
A slime mold Amoeba - heterotrophic
21
Kingdom Fungi Eukaryotic Most are multicellular
Heterotrophic (decomposers) Cell walls made of chitin
22
Absorbs nutrients from their environment to make food.
Decompose (break down) the tissues of other organisms Can not move from place to place Can grow very quickly
23
Kingdom Fungi Stilton cheese Bread mold
24
Kingdom Plant Eukaryotic Multicellular Autotrophic
Cell wall of cellulose; chloroplasts present
25
Kingdom Plantae
26
Kingdom Animalia Eukaryotic Multicellular Heterotrophic
No cell walls, no chloroplasts
27
Kingdom Animalia Flatworm Sponge Jellyfish Octopus Coral snake Bear
