Hierarchy of Life
2
SUBATOMIC PARTICLES
3
ATOMS Smallest structural unit of matter
4
ELEMENTS Groups of same atom
5
MOLECULES COMPOUNDS ELEMENTS BOND TO FORM NONMETALS/NONMETALS
Covalent Bonds GLUCOSE METAL/NONMETAL Ionic Bonds WATER
6
ORGANIC MACROMOLECULES
CARBOHYDRATES ENERGY PROTEINS STRUCTURE AND FUNCTION LIPIDS STORED ENERGY COVERINGS NUCLEIC ACIDS STORE INFORMATION
8
EVERYTHING UP TO THIS POINT IN THE HIERARCHY IS NON-LIVING ABOVE THIS POINT LIVING
9
SMALLEST STRUCTURAL UNIT OF LIFE CELLS
PROKARYOTIC EUKARYOTIC NO NUCLEUS BACTERIA NUCLEUS PROTISTS, FUNGI,PLANTS,ANIMALS
10
GROUP OF CELLS WORK TOGETHER BUT ARE NOT DEPENDANT ON EACH OTHER
COLONIAL GROUP OF CELLS WORK TOGETHER BUT ARE NOT DEPENDANT ON EACH OTHER ALGAE (autotrophic) SPONGES (heterotrophic)
11
TISSUES GROUP OF SPECIALIZED CELLS HAVING SAME FUNCTION ARE DEPENDANT ON EACH OTHER
12
SPECIALIZED TISSUES PERFORM SAME FUNCTION
ORGANS SPECIALIZED TISSUES PERFORM SAME FUNCTION
13
SPECIALIZED ORGANS PERFORM SAME FUNCTION
SYSTEMS SPECIALIZED ORGANS PERFORM SAME FUNCTION
14
IT SHOULD BE UNDERSTOOD THAT LIVING ORGANISMS EXIST AT ALL LEVELS
CELLULAR COLONIAL TISSUE SIMPLE ORGANS SIMPLE SYSTEMS
15
FINAL LEVELS ILLUSTRATE THE RELATIONSHIP BETWEEN THE ORGANISM AND ITS EXTERNAL ENVIRONMENT: ECOLOGY
16
KINGDOMS In Linnaean Taxonomy the Kingdom is the largest group into which organisms can be classified Organisms are placed into a Kingdom based upon three criteria: Type of Cell: Prokayotic/Eukaryotic Level of Organization: Unicellular/Multicellular Method of Energy Conversion: Autotroph/Heterotroph 6 KINGDOMS ARCHAEBACTERIA FUNGI EUBACTERIA PLANTAE PROTISTA ANIMALIA
17
Directions: 6 Kingdoms Chart
TEXT Holt Biology(Owl) pg , pg Glencoe Biology(Zebra) pg Complete the chart with this information: TYPE OF CELL PROKARYOTIC/EUKARYOTIC METABOLISM(Energy Conversion) AUTOTROPHIC(photosynthetic or chemosynthetic) HETEROTROPHIC CELL NUMBER(Level of Organization) UNICELLULAR/MULTICELLULAR REPRODUCTION ASEXUAL/SEXUAL SYMMETRY Cross out this category, use the space for more examples EXAMPLES LIST EXAMPLES FROM THE MAJOR GROUPS WITHIN THE KINGDOM
18
Highest level of organization in Linnaean Taxonomy
kingdoms
19
ARCHAEBACTERIA “old-bacteria”
Type of Cell Prokaryotic Metabolism Autotrophic (Chemo/Photo) and Heterotrophic Cell Number Unicellular Reproduction Asexual: Binary fission Examples Thermoacidophiles: volcanic vent bacteria, 3 &4 Methanogens: decomposition/digestion, 1 Halophiles: salt loving, 2
20
EUBACTERIA “True-bacteria”
Type of Cell Prokaryotic Metabolism Heterotrophic, some Photosynthetic Autotrophs Cell Number Unicellular Reproduction Asexual: Binary Fission Examples Disease causing bacteria, probiotics, decomposing strep E. coli staph Spirillus: spiral Cocci: round Bacillus: rods
21
PROTISTA “First-organism”
Type of Cell Eukaryotic Metabolism Photosynthetic Autotrophs/ Heterotrophs Cell Number Unicellular/ Multicellular Colonials Reproduction Asexual : Mitosis Examples Algae, seaweed, ‘zooplankton’, ‘phytoplankton’ paramecium volvox amoeba spirogyra plasmodium dinoflagellates euglena
22
FUNGI “sphongus” Greek for sponge-like
Type of Cell Eukaryotic Metabolism Heterotrophic: saprophyte(absorb from decomposition) Cell Number Unicellular/ True Multicellular Reproduction Asexual: mitosis Sexual: gamete union Examples Yeast, molds, mildew, mushrooms, puffballs Penicillium mold toadstools brackett Black mold yeast mushroom puffball
23
PLANTAE mosses Type of Cell Eukaryotic Metabolism
Photosynthetic Autotrophs Cell Number True Multicellular Reproduction Asexual: budding, runners Sexual: meiosis Examples moss, ferns, conifers, flowering mosses ferns conifers flowering
24
ANIMALIA birds Type of Cell Eukaryotic Metabolism
Heterotrophic (consume nutrients) Cell Number Multicellular Colonial / True Multicellular Reproduction Asexual (regeneration) Sexual Examples invertebrates, fish, amphibians, reptiles, birds, mammals mammals invertebrates amphibians birds fish reptiles
