Classification Classification & Taxonomy The naming and grouping of organisms based on similarities (in DNA, structure, etc.) Aristotle’s System of Classification – Why was it wrong? Theories change! 2. Explain the meaning and give examples of scientific names. Prior to DNA knowledge….only based on structural similarities. Not always accurate, for example not all green organisms are plants! As the microscopes improved do did our knowledge of DNA and true relatedness so theories changed. What is Linnaeus’ Classification System based on? Prior to DNA knowledge…..he based classification groups on similarities in structure (comparative anatomy such as homologous structures). 3. If Felis leo is the scientific name for a lion what could you infer about Felis tigre? Explain. Binomial Nomenclature (Genus species) A two word naming system in Latin….made up of an organism’s Genus and species names. Human is (Homo sapiens) SUMMARY 3 BELLRINGER: Essential Questions: The Language of Scientific names vs. common names 1. Why is binomial nomenclature useful? Scientific names are in Latin and composed of the taxon Genus and species. Common names are not useful worldwide since they are based on many different languages. Taxonomic Rankings – Taxa 2. Explain the taxonomic classification chart; citing which taxa is largest, smallest, most related. K P C O F G S 3. Members of the same species must be able to do what? The largest taxa with the largest amount of organisms is __________Kingdom________ The smallest taxa with the smallest amount of organisms is _____species__________ Organisms in this taxa can breed and produce offspring ________ species_________ If an organism belongs to the same class what other taxa does it have in common ______kingdom_________, ______phylum__________ In which taxa would DNA samples be the most common ________species________ SUMMARY 4 BELLRINGER: Essential Questions: 1. Give examples of differences and similarities among the kingdoms. 2. Name the 6 kingdoms from least to most complex.

Archaebacteria Eubacteria Protista Fungi Plantae Animalia How are Evolutionary Relationships Determined Structural Similarities Comparing anatomy, physical structures, bones, homologous structures to determine relatedness and common ancestry. 3. Protista are a very large and diverse group. Can you think of why they may be separated into two kingdoms someday soon? Breeding Behavior Comparing behaviors related to reproduction and development, such as attracting a mate to determine relatedness and ancestry. Geographical Distribution Comparing the location on Earth where organisms live and have lived to determine relationships and ancestry. Chromosome Comparison Comparing the number and structure of chromosomes in organisms to determine relationships and ancestry. Biochemistry Comparing the DNA, amino acids, enzymes, proteins of organisms to determine relatedness and ancestry. SUMMARY 5 BELLRINGER: Essential Questions: Phylogeny 1. How do you find a common ancestor on a Cladogram? A diagram showing the evolutionary relatedness among organisms and tracing back to a common ancestor. Cladistics & Cladogram The study of phylogeny, ancestry, relatedness. 2. If lines on a Cladogram are close together and connect at a point behind, what does that suggest about those organisms? 3. From the previous page, what characteristics would you expect related organisms to share? SUMMARY 6 BELLRINGER: Essential Questions: To determine an organism’s kingdom answer three questions: 1. Give basic characteristics of a kingdom. 1. Is the organism prokaryotic or eukaryotic? Prokaryotic Unicellular organisms lacking a nucleus (bacteria only), simple Eukaryotic 2. If an organism is a prokaryote what does that tell you about it? Organisms with a nucleus, more complex 2. Is the organism unicellular or multicellular? Unicellular Organisms made of one cell, simple Multicellular Organisms made of many cells, complex 3. Is the organism autotrophic or heterotrophic (Nutrition Style)? 3. Draw a phylogenetic tree depicting the evolution of the 6 kingdoms. Autotrophic Organisms like plants and algae that can convert gases into glucose through photosynthesis….make their own food…producers Heterotrophic Organisms like consumers that cannot convert gases into glucose….cannot make their own food *The only prokaryotic kingdoms are ___Archaebacteria______ & ______Eubacteria_________ *The only unicellular kingdoms are _____Archaebacteria_______ , ________Eubacteria_______ & _______Protist________ SUMMARY 7 BELLRINGER: Essential Questions: Complete the table below. 1. Name an organism that could be both autotrophic and heterotrophic? 2. Why is this type of organism significant in evolution? 3. Explain why theories of classification have changed through the years. SUMMARY Characteristic Archaebacteria Eubacteria Protist Fungi Plant Animal Cell Type (Prokaryote or Eukaryote) Nucleus present (yes or no) Unicellular or Multicellular Nutrition Style (Autotroph or Heterotroph or Both) Cell Wall (yes or no) Locomotion (yes or no or some) PRO PRO EUK EUK EUK EUK NO NO YES YES YES YES UNI UNI UNI MUL MUL MUL HETERO Mostly HETERO HETERO HETERO AUTO HETERO Or AUTO YES YES SOME YES YES NO YES YES SOME NO NO YES 8 BELLRINGER: Essential Questions: 1. Compare and contrast the two types of sexual reproduction. LIFE FUNCTIONS – ALL ORGANISMS SHARE No matter how big or small (multicellular or unicellular), autotrophic or heterotrophic, prokaryotic or eukaryotic……all organisms do the following life functions…..just in different ways! What is an organism? A living thing that is made of cells and carries out life functions listed below. Review in evolutionary order the 6 kingdoms of life: Archaebacteria, Eubacteria, Protist, Fungi, Plant, Animal All organisms are made of _____Cells_________ Life Functions 2. Compare and contrast the two types of respiration. Reproduction (Sexual vs. Asexual) Growth Regulation (Homeostasis) (Dynamic Equilibrium) 3. Give some examples of homeostasis in or organism. Nutrition (Autotroph vs. Heterotroph) Respiration (Aerobic vs. Anaerobic) Transport Excretion Synthesis SUMMARY Life process to produce offspring to continue that species. Sexual requires two different parents resulting in different offspring through meiosis. Asexual requires one parent resulting in a cloned identical offspring through mitosis. Life process to increase in cell size and/or number Life process to maintain a balanced internal environment. Regulation of all other life functions. Dynamic Equilibrium includes small fluctuations to maintain stability. Life process of obtaining nutrients for energy, either by autotrophic photosynthesis or by heterotrophic consuming. Life process of converting glucose nutrients into usable ATP/energy for all cells. Aerobic uses Oxygen and Anaerobic does not. Life process to circulate, move, absorb, distribute, diffuse molecules within an organism/cells. Life process to remove metabolic cellular wastes. Life process to make/produce a larger molecule by the combining of smaller molecules. 9 BELLRINGER: Essential Questions: How do different organisms accomplish the same function: 1. What happens if an organism fails to maintain homeostasis? Comparing Unicellar Organisms Organelles Small cellular parts with specific functions, able to complete life functions in unicellular organisms. 2. Which life function is not necessary for the individual but it is for the survival of the species? Explain. 3. Homeostasis and Regulation are synonyms explain. Vs. Multicellular Organisms Cells-tissues-organs-systems Many cells make up tissues….many tissues make up organs…and many organs make up systems. Multicellular organisms require more than cells to perform life functions since not all cells are in direct contact with their environment. Life Function Respiration Organs/System Mitochondria Lungs/Respiratory Stomach/Digestive Transport Cell Membrane, Food Vacuole Cell Membrane, Waste Vacuole Cytoplasm Reproduction Nucleus Testes & Ovaries/Reproductive Nutrition Excretion SUMMARY Organelles Kidneys/Excretory Blood/Circulatory 10 BELLRINGER: Essential Questions: The Prokaryotes 1. Give examples and characteristics of the former Monerans. Prokaryotic, Unicellular, Heterotrophic, Anaerobic Organisms. First organisms to appear on Earth about 4 billion years ago. Live in extreme harsh environments. 2. What types of environments would you find Archaebacteria in? Archaebacteria Eubacteria Prokaryotic, Unicellular, Heterotrophic, Organisms. Found in air, water, soil, and other organisms. Some are decomposers, some are disease causing. The role of Eubacteria in our Environment: Beneficial Decomposers AKA nitrifying bacteria and denitrifying bacteria because they convert Nitrogen wastes into usable nitrogen for soil and plants. 3. Explain how the reproduction rate of bacteria allows them to evolve quickly. Pathogenic Bacteria that cause disease, illness, and death. -Ways to control Pathogens Washing/good hygiene, freezing, canning, salt preservatives, antibiotics -The problem with Resistant Pathogens (MRSA) Bacteria that have mutated and are stronger than others….able to resist antibiotics….reproduce and pass on their mutation and resistance is passed on to their offspring. SUMMARY 11 BELLERINGER: Essential Questions: The Eukaryotes 1. Give examples of life functions that single celled Protists do as well as multi celled animals. Protista (Protists) Eukaryotic, Unicellular, Heterotrophic (animal like), Autotrophic (plant like), mostly live in water. Ameba, Paramecium, Algae -adaptations: structures for locomotion in animal like-cilia, pseudopods, flagella may live in colonies for safety in numbers 2. Compare an organelle to a human organ in function. Fungi (Fungus) Eukaryotic, Multicellular, Heterotrophic by absorbing decaying materials (decomposers) -adaptations: Reproduce asexually by spores 3. Compare an organelle to a human system in function. Plantae (Plants) Eukaryotic, Multicellular, Autotrophic by Photosynthesis, have Cell Walls. -adaptations: Produce flowers and smells to aid in sexual reproduction. Animalia (Animals) Eukaryotic, Multicellular, Heterotrophic, Locomotive. Most have specialized organs and systems for life functions. SUMMARY 12 BELLRINGER: Essential Questions: ONLY THE LIVING ARE CLASSIFIED!!!! 1. Why are viruses not considered living? WHAT ABOUT VIRUSES? Viruses are not classified…they are exceptions…why? Viruses are not made of cells and therefore are not considered a living organism, BUT they can reproduce! 2. Explain what a vaccination is and give an example. Viruses as Pathogens & Examples Viruses cause disease, illness, death. Polio, Measles, Mumps, HIV, Meningitis, FLU Viruses in Health and Medicine Vaccinations A dead pathogen injected into an organism to cause an immune response. WBC’s produce specific antibodies to destroy the antigen in the vaccine. Memory WBC’s retain the antibodies to fight future attacks. 3. Discuss objections to people being vaccinated…or forced vaccinations for their children. SUMMARY 13 BELLRINGER: Essential Questions: What is a Dichotomous Key? 1.
