Transcript

  • 1. Good Afternoon, For your warm-up today, without consulting your notes, please draw a graphic that shows what you know about how the following words are related in terms of organization: Organ, Cell, Tissue, Organism, Organ System Need a hint or a start?
  • 2. Physical Science, and Chemistry Extension: Where would you add the following words to your graphic?: Organelle, Atom, Molecule An organelle is a structure within a cell that performs a function. It is made of different molecules. An atom is the smallest particle of an element. A molecule is a collection of atoms held together by bonds. Does this agree with how your added these words to your chart? If Yes - Congratulations! If not, re-work your chart.
  • 3. Cells The basic building blocks of life
  • 4. All Cells~ have a cell membrane contain heredity material in the form of DNA have cytoplasm and organelles are small
  • 5. Cell Theory All organisms are composed of one or more cells The cell is the basic unit of life All cells come from existing cells
  • 6. What are the three statements included in cell theory? Thank you Miranda 1) All organisms are composed of ________________. one or more cells 2) The cell is____________________________. the basic unit of all living things 3) All cells come from _____________. existing cells
  • 7. There are _____types of cells. two Prokaryotes Eukaryotes • Membrane bound nucleus Examples: Examples: • No true nucleus that houses the cell’s DNA Protists FewBacteria structures • intracellular • Membrane bound internal • Usually single structures Fungi Archaea • Circular DNA • Usually found in multicellular Plants organisms Animals • Linear DNA
  • 8. Eukaryotes Holding it all together: All cells have an outer covering that separates what is inside the cell with what is outside. All cells have a cell membrane, and some cells have an additional layer outside the cell called a cell wall. Cell Membrane: All cells are covered with a cell membrane. It keeps the cytoplasm in, and allows nutrients in, wastes out, and interaction with other cells. Cell Wall: Plants and algae have a cell wall made of cellulose. The cell wall provides strength and support.
  • 9. Eukaryotes Organelles and what they do. Organelles contains the cell’s DNA The nucleus Nucleus and is the “control center” of the cell Organelles are structures in the cell that enable the cell to live, grow, and reproduce Read pages 68 - 74 in your textbook. Make a chart of the organelles and their specific functions. For Example:
  • 10. Organelles and what they do. The nucleus contains the cell’s DNA Nucleus and is the “control center” of the cell
  • 11. Cells Prokaryotes Eukaryotes Bacteria Archaea Plants Protists Fungi Animals
  • 12. Cells Eukaryotes Plants Protists Fungi Animals Animals
  • 13. Plant Cells Animal Cells Cell Diagram Web Quest •Cell Wall •Lysosomes •Chloroplasts •Centrioles •Large Vacuole •Flagella http://sun.menloschool.org/~cweaver/cells/
  • 14. On a white piece of paper from the back of the room please draw the following cells: One example of a Prokaryote One example of a Eukaryotic cell from a plant One example of a Eukaryotic cell from an animal
  • 15. Prokaryote: Bacteria Eukaryote: Plant Eukaryote: Animal Maybe you will divide your paper like this.
  • 16. Plant Cells Plant cells have
  • 17. Bacillus anthracis Bacteria Pseudomonas aeruginosa http://www.stephenjaygould.org/library/gould_bacteria.html http://en.wikipedia.org/wiki/Bacterium Holt Science and Technology, Life Science, pgs 224 - 232 (this is your text book)
  • 18. Scientific Name Pyrolobus Comments Pyrolobus, the Archaea organism with the highest known growth temperature (113°C). Scientific Name Pyrodictium Most archaea live in Earth’s most extreme environments, like salty lakes, boiling hot springs, deep ocean thermal vents, and environments that completely lack oxygen. They are the radically extreme life forms of the planet, and are sometimes called Extremophiles (lovers of extreme environments.) Archaea live inside cow’s stomachs, and are the reason cows burp and errr.... expel Methane gas. We can use these organisms to convert garbage and poop into methane - which is a valuable fuel. Archaea have characteristics in common with both Bacteria and Eukaryotes.
  • 19. Please find some more information on the following words: Cell membrane DNA Cytoplasm organelles are small Done?
  • 20. It might look something like this:
