TOPIC: Cells ISN PAGE 92-93 Mon 11.27.12 MY GOAL: I will differentiate between plant & animal cells Get On Task 1. PICK UP Daily Formative at table 2. ATTACH to INS p.92 3. COMPLETE NOW using ISN p.90 for help NOTES: Organelles, Surface Area REVIEW: Cell Organelles WORKSHEETS: Cell Types ISN p.94-95 Cell Structure A Few NOTES on ISN p. 93 #1. Organelles A) CILIA vs short many Eukaryotic cells Prokaryotes FLAGELLA long fewer Eu & Cilia on Protist Respiratory Cilia in Lung Epithelium The cilia are bathed in nasal mucus. The mucus moisturizes the air but also, like fly paper, filters dust , pollen, chemicals, bacteria and viruses that enter our nose as we breath. The cilia are always refreshing the mucus coating of the nose. In coordinated waves, they sweep a layer of mucus to the back of the nose every 5-8 minutes. The mucus then slips into the throat where it is swallowed, rather than inhaled into the lungs. The acid of the stomach destroys the harmful nasal debris. B) CytoSkeleton– – provides structure to cell connects to every part of CM & organelles C) MicroFilaments Smaller Under CM Contraction of cells (cytokinesis) vs MicroTubules Larger Throughout cell Scaffold BOTH allow cell to hold shape, & move itself its organelles. NOTES, cont. on ISN p. 93 #2. Surface Area… A. Mitochondria B. Chloroplast C. Endoplasmic Reticulum PROKaryotic Cells vs EUKaryotic Cells and PLANT CELL vs Animal Cell 1. ATTACH packet page 5 & 6 to ISN pages 94 & 95 2. COMPLETE 3. REVIEW with neighbor http://www.diffen.com/difference/Animal_Cell Stop Think And Review Questions to think about… 1. 2. Do plant cells have a cell wall? Do animal cells have a cell wall? 3. 4. Do plant cells have a cell membrane? Do animal cells have a cell membrane? 5. 6. Do plant cells have chloroplasts? Do animal cells have chloroplasts? 7. 8. Do plant cells have mitochondria? Do animal cells have mitochondria? 9. 10. Do plant cells have a large vacuole for support? Do animal cells have a large vacuole for support? PROkaryotic vs EUkaryotic Cells Similarities & DNA, Cytoplasm, Membrane, Ribosomes 94 Cytoplasm Differences NUCLEUS, Complexity Golgi Body C.Membrane N.Membrane C.Wall NUCLEUS DNA ER Ribosomes Mitochondria Plant Cell vs Animal Cell Similarities Nucleus & C.Membrane & Organelles & (except Chloroplast) Differences No C.Wall, No Chloroplast, Vacuole size, Shape Vacuole 95 ER Chloroplast Nucleus C.Wall Mitochondria C.Membrane ER Mitochondria Cytoplasm Vacuole Chloroplast Cytoplasm Work out a pathway form the Nucleus to the Cell Membrane that would keep Protein from ever entering the Cytoplasm 1. Nucleus to 2. ER to 3. Vesicle to 4. Golgi to 5. Vesicle to 6. Cell Membrane Stop Think And Reflect 1. Cell wall…… 1. Protective outer covering of a plant, fungus, or bacterial cell 2. 3. 4. 5. DNA………… ER…………… Chloroplast.. Cytoplasm…. 2. Contains genetic instructions 6. Cell membrane... 6. Helps to maintain homeostasis in cells; outside of animal cells 7. Ribosomes…. 8. Mitochondrion.. 9. Nucleus…….. 10. Golgi body… 11. Lysosome… 3. Transport channels 4. Used for photosynthesis 5. Jelly-like substance where chemical reactions take place 7. Make proteins 8. Coverts energy in food to usable energy 9. Control center of cell 10.Packaging area of cell 11.Contains enzymes HOMEWORK 1. MiniSummative #2 tomorrow Study ISN pages 88-95 2. You MUST Study!!! Be the change you wish to see in the world
