  1. 1. Classification to the Fungi Biology I Factoids
  2. 2. Factoid 188 <ul><li>Section 11 </li></ul><ul><li>Taxonomy is the branch of biology that specializes in classifying organisms into taxa (or groups) </li></ul>
  3. 3. Factoid 189 <ul><li>The 7 levels of classification in order from largest to smallest is kingdom, phylum, class, order, family, genus, species. </li></ul>
  4. 4. Factoid 190 <ul><li>Scientific names are made up of the genus name plus the species name. </li></ul>
  5. 5. Factoid 191 <ul><li>The genus name is always capitalized and the species name is always lower case. </li></ul><ul><li>Scientific names are always either underlined or in italics. </li></ul>
  6. 6. Factoid 192 <ul><li>Organisms are named using a system created by Carolus Von Linnaeus called binomial nomenclature which means “two part name.” </li></ul>
  7. 7. Factoid 193 <ul><li>Common names are not used because of differences in languages. They are also not specific. People call the same organism various common names. </li></ul>
  8. 8. Factoid 194 <ul><li>Scientific names are written in Latin because all educated people during Linnaeus’ time spoke Latin. </li></ul>
  9. 9. Factoid 195 <ul><li>2000 years ago Aristotle created the first system of classification with two kingdoms: Plant and Animal. </li></ul>
  10. 10. Factoid 196 <ul><li>Aristotle’s system remain in place until the invention of the microscope. They discovered microscopic organisms that looked like animals but acted like plants. This led to the creation of Kingdom Protista. </li></ul>
  11. 11. Factoid 197 <ul><li>A dichotomous key is a tool used in classification. One is given a set of questions to be answered. The answer leads you to the organisms classification. </li></ul>
  12. 12. Factoid 198 <ul><li>Since viruses are not alive they are not classified into any kingdom. </li></ul><ul><ul><li>They do not satisfy the characteristics of life from the first chapter we discussed. </li></ul></ul><ul><ul><li>They do not grow, develop, or carry out respiration. </li></ul></ul><ul><ul><li>Examples include mumps, measles, chicken pox, the flu, or even a cold . </li></ul></ul>
  13. 13. Factoid 199 <ul><li>The only way viruses are able to reproduce is inside a living cell called a host. </li></ul><ul><li>Viruses contain a core of nucleic acid that can either be DNA or RNA </li></ul><ul><li>Around the nucleic acid is a layer of protein called a capsid . </li></ul>
  14. 14. Factoid 200 <ul><li>Sometimes viruses have a lipid outer layer called an envelope. </li></ul><ul><li>Once inside a host cell, the viral DNA hijacks the cell and the cell makes viral genes and viral proteins. </li></ul><ul><li>Viruses are treated with antivirals NOT antibiotics. </li></ul>
  15. 15. Factoid 201 <ul><li>Kingdom Archaebacteria </li></ul><ul><li>They are prokaryotic – no nucleus or other membrane-bound organelles. </li></ul><ul><li>Archaebacteria live in extreme environments. Their cells walls do not contain peptidoglycan. </li></ul>
  16. 16. Factoid 202 <ul><li>Kingdom Eubacteria </li></ul><ul><li>Most common bacteria </li></ul><ul><li>Prokaryotic </li></ul><ul><li>Have peptidoglycan </li></ul><ul><li>Bacterial Shapes </li></ul><ul><ul><li>Three basic shapes are common: </li></ul></ul><ul><ul><ul><li>Coccus – Round shaped </li></ul></ul></ul><ul><ul><ul><li>Baccillus – Rod shaped/cylindrical </li></ul></ul></ul><ul><ul><ul><li>Spiral </li></ul></ul></ul>
  17. 17. Factoid 203 <ul><li>Kingdom Protista </li></ul><ul><li>Animal-like Protists </li></ul><ul><ul><li>They are heterotrophic which means they don’t make their own food. </li></ul></ul><ul><ul><li>Include amoeba </li></ul></ul><ul><li>Plant-like Protists </li></ul><ul><ul><li>They are autotrophic which means they make their own food. </li></ul></ul><ul><ul><li>Include euglena </li></ul></ul><ul><li>Fungi-Like Protists </li></ul><ul><ul><li>They absorb their food like fungi </li></ul></ul><ul><ul><li>Include slime molds </li></ul></ul>
  18. 18. Factoid # 204 Kingdom Fungi <ul><li>Characteristics of Fungi </li></ul><ul><ul><li>Fungi are heterotrophs that utilize organic matter. </li></ul></ul><ul><ul><ul><li>Saprobes get their nutrients from breaking down dead organic matter. </li></ul></ul></ul><ul><ul><ul><li>Parasitic thrive on tissues in living hosts </li></ul></ul></ul><ul><ul><li>All fungi rely on extracellular enzymatic digestion and absorption </li></ul></ul><ul><ul><li>Cell walls of chitin </li></ul></ul>
  19. 19. Factoid #205 <ul><li>Lichens </li></ul><ul><ul><li>Symbiotic relationships between a fungus and an algae </li></ul></ul><ul><ul><li>Fungus protects the algae; the algae gives the fungus food. </li></ul></ul><ul><ul><li>3 types </li></ul></ul><ul><ul><ul><li>Crustose </li></ul></ul></ul><ul><ul><ul><li>Foliose </li></ul></ul></ul><ul><ul><ul><li>fruticose </li></ul></ul></ul>
