  1. Wednesday May 21Agenda, Flashcards, Notes & Assignment

  2. Agenda • Copy the next four flashcards you will find them after this slide • The journal entry can be found after the flashcards – as always complete this in your journal • The next set of notes is located after the journal entry – be sure to copy them into your handbook • I have left a copy of the assignment you are to complete – you may write on the copy. • Biol Apps 7.1 & 7.2 will be due on Friday (I would start these when you are finished with everything)

  3. Function of the Cell Membrane Selectively permeable (regulates materials coming in/out of the cell) Phospholipid Bilayer HOMEOSTASIS Flashcard 5 Back Front

  4. Differences between Plant and Animal Cells Plant Cells – have cell walls, chloroplasts, large vacuoles Animal Cells – have Centrioles (used for cell division) *BOTH ARE EUKARYOTIC! (have membrane bound organelles and a nucleus) Flashcard 6 Back Front

  5. What happens when cells are placed in a saltier environments? Why? Cells lose water in saltier than usual environments because of osmosis!! Flashcard 7 Back Front

  6. Functions Of Enzymes “Lock and Key” Acts as a “catalyst” (speed up reactions) Lowers activation energy Works best at “Optimum” conditions! (this is different for each enzyme) Flashcard 8 Back Front

  7. Entry 53 5/21 CLASSIFICATION INQUIRY • You are going to CLASSIFY and group your animals based on similar characteristics. • First start with the most GENERAL grouping for all of your organisms and make this your title • Now group your animals into multiple groups based on the characteristics they have in common • Continue to narrow down your grouping– make sure to write this down IN YOUR JOURNAL Title

  8. Classification and Speciation Isn’t everything living either a plant or an animal? • First Classification System • Devised by Aristotle • Two basic groups: plant and animal.

  9. Modern Classification System • Devised by Carl Linnaeus (1707-1778) • Created a system called Binomial Nomenclature • Every organism receives two names Genus and Species • The genus specie name is written in a specific format • Italicize = Homo sapiens • Underline = Homo sapiens • Homo is the genus, sapiens is the species

  10. Biological Taxonomy • TAXONOMY is the study of classification • DOMAIN is the highest taxonomic rank of organisms • Domain system consists of three domains: • Archae • Bacteria • Eukarya

  11. Taxonomy • Seven levels of TAXA were created • Kingdom Most General (only 6 Kingdoms) • Phylum • Class • Order • Family • Genus • Species Most Specific (~2 million identified) King Philip Came Over For Green Soup

  12. Taxonomy • Specie is the most specific of these seven taxa, thus the specie would contain only one type of organism. • Specie is defined as a group of organisms which can interbreed and produce fertile offspring.

  13. Basis for Classification • Linnaeus Classification • Morphology: Shared physical characteristics • Example: Animals – Type of Heart (2 chambers vs 4 chambers) and Blood, live birth vs egg, antennae, wings, etc. • Example: Plants – Number of Stamens (male parts), number of styles (female parts)

  14. Modern Classification • Biochemical analysis: gram staining bacteria, or comparing DNA and amino acid sequences • Embryology: common fetal development

  15. Modern Classification • Phylogeny: describes the evolutionary relationships between organisms. • Example: Homologous/Analogous structures used to determine relationships

  16. Modern Classification • Phylogenetic Trees are used to show a visual representation of the evolutionary relationships • Phylogenetic Tree - each node represents the inferred most recent common ancestor, and the edge lengths may be interpreted as time estimates.

  17. Type of Phylogenetic Tree • Cladogram– specific type of phylogenetic tree which emphasize the order in which derived characteristics arise from a phylogenetic tree

  18. Tools used in Classification • Phylogenetic Tree/Cladogram • Dichotomous Key • Uses paired statements and visible characteristics to “key out” an organism and identify it.

  19. Assignment • I have a left a classification webquest the sub will pass it out to you. • You may write on it • Turn it in when you are finished and start your Biol Apps 7.1 & 7.2 they will be due on Friday
