  1. CELL THEORYENDOSYMBIOTIC THEORY http://www.parlament-berlin.de/Galeriecopy.nsf/0/8ABC720262898739C1256A480037F869?OpenDocumen http://www.ncu.edu.tw/~ls/graph/faculty_pictures/whole_time/SLC/SLC_lab-1.jpg t

  2. CELL THEORY 1. All living things are ________________________. MADE OF CELLS 2. Cells are the basic unit of ____________ & _____________ in an organism. (cell = basic unit of _____________) STRUCTURE FUNCTION life 3. Cells come from the reproduction of ____________ cells existing Cell image: http://waynesword.palomar.edu/lmexer1a.htm

  3. 1970- American Biologist _____________________ Provided evidence for the idea that ancestors of ____________ + _____________were at one time free-living prokaryotes that were engulfedby other cells and stayed to live symbiotically inside = _________________________ Lynn Margulis Mitochondria chloroplasts Endosymbiotic Theory http://en.wikipedia.org/wiki/Lynn_Margulis

  4. ENDOSYMBIOTIC THEORY See a movie about ENDOSYMBIOTIC THEORY http://www.mun.ca/biology/scarr/Endosymbiosis_theory.gif

  5. Bacterial plasma membrane Vesicle

  6. Bacterial DNA Bacterial ribosomes

  7. Remember host cell is a eukaryote. Add a nucleus and host DNAHow is this different from bacterial DNA? Host Nucleus HOSTDNA

  8. Add some eukaryotic host ribosomes. How are these different from bacterial ribosomes? HostRIBOSOMES

  9. Evolved to becomemitochondrion

  10. Bacterial cell membrane (CRISTAE) Evolved to becomemitochondrion Vesicle OUTER MITOCHONDRIAL MEMBRANE

  11. WHAT’s the EVIDENCE? Look at the colors in your picture.Which parts of mitochondria/chloroplasts have a prokaryotic bacterial origin?Which have a eukaryotic host origin? Make a list of the evidence for the ENDOSYMBIOTIC THEORY?Find these in your picture!

  12. LYNN MARGULIS CELL THEORYENDOSYMBIOTIC THEORYENDOSYMBIOTIC THEORY Proposed by ______________________Ancient prokaryotes were taken in by eukaryotic cells and stayed to live inside them in a symbiotic relationship; eventually lead to mitochondria and chloroplast organellesExplains origins of _________________ and ____________________ EVIDENCE: MITOCHONDRIA/CHLOROPLASTS 1. are only cell parts with __________________ and ____________ 2. have ____________________like bacteria 3. have _________________ in their inner membranes like bacteria 4. divide using ___________________ like bacteria 5. have a SINGLE, CIRCULAR loop of DNA like bacteria MITOCHONDRIA CHLOROPLASTS OWN DNA DOUBLE MEMBRANES RIBOSOMES PHOSPHOLIPIDS BINARY FISSION

  13. All living things made of cells BUT… organisms can be very different. Image from: http://www.agen.ufl.edu/~chyn/age2062/lect/lect_06/bacsiz.GIF UNICELLULAR MULTICELLULAR http://www.angelbabygifts.com/ http://www.inclusive.co.uk/downloads/images/pics2/tree.gif

  14. CELL SIZE http://facstaff.bloomu.edu/gdavis/links%20100.htm Typical cells range from: 5 – 50 micrometers (microns) in diameter

  15. How big is a micron ( µm ) ? http://www.talentteacher.com/pics/005cb.jpg 1 cm = 10,000 microns 1” = 25,000 microns

  16. They have different kinds of cells doing different jobs MULTICELLULAR ORGANISM don’t just contain MANY CELLS. Image from: http://www.isscr.org/images/ES-cell-Fig-2.jpg

  17. Cells in a multi-cellular organism become SPECIALIZED by turning different genes on and off Image from: http://www.ncu.edu.tw/~ls/graph/faculty_pictures/whole_time/SLC/SLC_lab-1.jpg Cell Specialization =DIFFERENTIATION

  18. SPECIALIZED ANIMAL CELLS Red blood cells Muscle cells http://www.biologycorner.com/bio3/images/bloodcells3D.jpg Cheek cells http://www.mlms.logan.k12.ut.us/~ajohnson/Cells.html

  19. Specialized Plant cells Guard cells Xylem cells Pollen Guard cells: http://botit.botany.wisc.edu/courses/img/Botany_130/Diversity/Bryophytes/Anthoceros/Guard_cells.jpg Xylem: http://botit.botany.wisc.edu/images/130/Secondary_Growth/Woody_Stems/Tilia_Stem/Secondary_Growth/One_Year_Stem/Primary_xylem_MC.jpg Pollen: http://www.uic.edu/classes/bios/bios100/labs/pollen.jpg

  20. How Do Cell Compare? Plant cells Animal cells _________> _________> _________ Bacterial cells http://slideplayer.com/slide/3524544/12/images/16/Bacterial+cell+Animal+cell+Plant+cell.jpg

  21. CELL THEORY CELLS • All living things are made of _______ 2. Cells are the basic unit of structure & function in an organism. (= basic unit of ______) 3. New cells are produced from _____________cells. life existing Cell image: http://waynesword.palomar.edu/lmexer1a.htm

  22. ________ __________  ___________ MOLECULES ORGANELLES ATOMS IMAGE SOURCES: see last slide

  23. ____________  ____________  CELLS TISSUES Similar cells working together IMAGE SOURCES: see last slide

  24. ___________  __________ ___________ ORGAN SYSTEMS ORGANS ORGANISM Different tissuesworking together Different organsworking together IMAGE SOURCES: see last slide

  25. SOUTH DAKOTA SCIENCE STANDARDS Students will be able to: • explain the process of specialization 9-12.L.1.3.A (ADVANCED) • describe the relationships between the levels of organization in multi-cellular organisms(cells, tissues, organs, organ systems, and organism) (PROFICIENT) • explain how gene expression regulates cell growth and differentiation 9-12.L.1.3.A(Tissue formation, development of new cells from original stem cells (ADVANCED)

  26. NATURE OF SCIENCE: Indicator 1: Understand the nature and origin of scientific knowledge. 9-12.N.1.1. Students are able to evaluate a scientific discovery to determine and describe how societal, cultural, and personal beliefs influence scientific investigations and interpretations. • Recognize scientific knowledge is not merely a set of static facts but is dynamic and affords the best current explanations.

  27. SOUTH DAKOTA ADVANCED SCIENCE STANDARDS 9-12.L.1.3A. Students are able to explain how gene expression regulates cell growth and differentiation. Examples: Tissue formation Development of new cells from original stem cells
