Presentation Transcript

  1. MITOSIS AND ASEXUAL REPRODUCTION

  2. MITOSIS AND ASEXUAL REPRODUCTION • WHAT ARE ALL THE LIFE PROCESSES? • H.N.T.R.S.G.E.R.M.R • WHICH ONES HAVE WE COVERED? • H.N.T.R.S.G.E.R.M • WHAT’S LEFT? • R  REPRODUCTION!! • WHAT IS REPRODUCTION?

  3. MITOSIS AND ASEXUAL REPRODUCTION • REPRODUCTION • THE PROCESS BY WHICH LIVING THINGS PRODUCE NEW ORGANISMS OF THEIR OWN KIND

  4. MITOSIS AND ASEXUAL REPRODUCTION • HOW DOES REPRODUCTION WORK? • REMEMBER:ALL CELLS ARISE FROM PRE-EXISTING CELLS • THE PROCESS BY WHICH CELLS MAKE MORE CELLS IS CALLED… • CELL DIVISION

  5. MITOSIS AND ASEXUAL REPRODUCTION • CELL DIVISION CAN BE BROKEN INTO TWO CATEGORIES • MITOTIC CELL DIVISION EXACT COPIES ARE MADE • MEIOTIC CELL DIVISION NOT EXACT COPIES ARE MADE • *WE WILL DISCUSS THIS ONE FURTHER NEXT CHAPTER*

  6. MITOSIS AND ASEXUAL REPRODUCTION • MITOTIC CELL DIVISON • CLICK THE PICFOR THECELL DIVISIONSONG

  7. MITOSIS AND ASEXUAL REPRODUCTION • MITOTIC CELL DIVISION • A.K.A. ASEXUAL REPRODUCTION • REPRODUCTION WITHOUT SEX (REQUIRING ONLY ONE PARENT CELL) • BROKEN INTO TWO PROCESSES • MITOSIS • CYTOKINESIS

  8. MITOSIS AND ASEXUAL REPRODUCTION • MITOSIS

  9. MITOSIS AND ASEXUAL REPRODUCTION • MITOSIS • THE CONTENTS OF THENUCLEUS ARE COPIEDAND THEN DIVIDED TO FORM TWO IDENTICALNUCLEI • WHY IS THIS SO IMPORTANT? IN OTHER WORDS, WHY DOES THIS NEED TO HAPPEN?(*HINT – WHAT’S IN THE NUCLEUS?)

  10. MITOSIS AND ASEXUAL REPRODUCTION • MITOSIS • LET’S BREAKDOWN THESTAGES OFMITOSIS • CLICK THEIMAGE FOR AVIDEO

  11. MITOSIS AND ASEXUAL REPRODUCTION • CYTOKINESIS • THE CYTOPLASM (CELL) DIVIDES IN TWO

  12. MITOSIS AND ASEXUAL REPRODUCTION • CYTOKINESIS • IN ANIMAL CELLS • CLEAVAGE FURROW • IN PLANT CELLS • CELL PLATE FORMATION • WHY IS THERE A DIFFERENCE WITH CYTOKINESIS AND NOT WITH MITOSIS?

  13. MITOSIS AND ASEXUAL REPRODUCTION • SHOULD MITOTIC CELL DIVISION HAPPEN ALL THE TIME? WHY OR WHY NOT? • SHOULD MITOTIC CELL DIVISION HAPPEN AT THE SAME RATE ALL THE TIME? WHY OR WHY NOT? • WHAT DO WE CALL MECHANISMS THAT CAN CHANGE THE RATE OF A REACTION?(*HINT  WHAT CONTROLS INSULIN PRODUCTION?

  14. MITOSIS AND ASEXUAL REPRODUCTION • WHAT’S A CONSEQUENCE OF MITOTIC CELL DIVISION HAPPENING UNCONTROLLABLY? CANCE R

  15. MITOSIS AND ASEXUAL REPRODUCTION • DON’T WORRY…NORMALLY A SPECIAL PROTEIN CALLED CYCLIN EXISTS THAT CONTROLS WHEN CELLS DIVIDE, SO THE “C” WORD IS KEPT IN CHECK

  16. MITOSIS AND ASEXUAL REPRODUCTION • MITOTIC CELL DIVISION AS A FORM OF REPRODUCTION • ASEXUAL ONLY • PRODUCES “IDENTICAL” OFFSPRING • FORMS OF ASEXUAL REPRODUCTION • BINARY FISSION • BUDDING • SPORE FORMATION • REGENERATION • VEGETATIVE REPRODUCTION (PROPAGATION)

  17. MITOSIS AND ASEXUAL REPRODUCTION • BINARY FISSION • BUDDING • SPORE FORMATION • REGENERATION • VEGETATIVE PROPAGATION

  18. MITOSIS AND ASEXUAL REPRODUCTION • THAT’S MITOTIC CELL DIVISION…BUT WHAT IF YOU DON’T WANT AN “IDENTICAL” OFFSPRING? • PRESENTING MEIOTIC CELL DIVISION…COMING NEXT CHAPTER 
