  1. Journal10/25 Photosyn What do you know about photosynthesis? What goes through this process? What reactants are needed for this process to happen? What is the point of photosynthesis? What are the products, or what comes out of photosynthesis?

  2. Photosynthesis & Cellular Respiration Provide us energy to do this: How does this: http://posthastetaste.com/wp-content/uploads/2006/06/chard.jpg http://www.snowlines.co.uk/acatalog/Chicago-2004-Evans-Rutto.jpg

  3. BackgroundEnergy and Living Things • Where does Energy come from? • Either directly or indirectly from the sun • Does Energy Flow? • Absolutely. • From one organism (notice this does not say only from one animal) to another • Quick Review: What is Metabolism? New Definition: Using E to build or break down molecules

  4. Student to Board: What comes into and out of plants? http://images.google.com/imgres?imgurl=http://www.homestead-farm.net/art/kidsArt/photosynthesis-color.jpg&imgrefurl=http://www.homestead-farm.net/KidsLinks/Photosynthesis.html&h=499&w=814&sz=38&hl=en&start=4&um=1&usg=__c_VKL-6TlFerh3eBtb2FYV3zQVc=&tbnid=M0f3YdE7pH2wYM:&tbnh=88&tbnw=144&prev=/images%3Fq%3Dphotosynthesis%26um%3D1%26hl%3Den%26sa%3DN

  5. Photosynthesis • Photosynthesis: process that converts light E to Chemical E ( turns light into food . . . WOW!) • A building part of metabolism • Light + H2O + CO2 C6H12O6 + O2 + H2O • Occurs in the chloroplast • Organisms that use energy from sunlight (or inorganic substances) to make organic (specifically sugar) compounds are called: autotrophs (auto = self, troph = feeder) • Organisms that get their E from food instead of directly from sunlight (or inorganic substances) are called: heterotrophs (hetero = different, troph = feeder)

  9. Structure and Function of the Leaf Answer the following questions in complete sentences to have them to study from: What is the cuticle for? Where are the stoma generally located? Are the stoma open or closed during the day? 4. What process takes place during the day? Name two substances (gases) released through the stomata. Name one substance taken up through the stomata? What do the stomata do at night? What is the advantage of the leaf being broad, flat and thin? The side view of a leaf: Up close view of stoma and guard cell (looking up from the bottom): Stoma

  10. We know where the energy originates from. We know how the gases get in and out of the plant. We know what the sun energy gets turned into . . . Sugar So, are plants filled with sugar, or do they get stored as something else? - stored as starch - in cell walls as cellulose (remember large carb, dogs can’t digest)

  11. Factors that affect Photosysnthesis -Temperature -Light concentration -Supply of water -Supply or concentration of CO2 -Minerals in soil -Ph levels -Time of day -Species

  12. Light Spectrum What colors of light are used by photosynthesis? - all but green What colors are in white light? - ROY G BIV See text Page 98 http://images.google.com/imgres?imgurl=http://www.bhphotovideo.com/images/spectrumbig.jpg&imgrefurl=http://www.bhphotovideo.com/find/Product_Resources/lighting1.jsp&h=299&w=500&sz=32&hl=en&start=5&tbnid=KWXjk0uRnrEe1M:&tbnh=78&tbnw=130&prev=/images%3Fq%3Dvisible%2Bspectrum%2Bthrough%2Ba%2Bprism%26gbv%3D2%26svnum%3D10%26hl%3Den%26safe%3Dactive http://images.google.com/imgres?imgurl=http://www.chem.purdue.edu/gchelp/cchem/prism_spectrum.jpg&imgrefurl=http://www.chem.purdue.edu/gchelp/cchem/color.html&h=309&w=500&sz=16&hl=en&start=14&tbnid=TyUd3uwe0WNuhM:&tbnh=80&tbnw=130&prev=/images%3Fq%3Dvisible%2Bspectrum%2Bthrough%2Ba%2Bprism%26gbv%3D2%26svnum%3D10%26hl%3Den%26safe%3Dactive

  13. Now that the sugar is made, how do organisms turn it into usable E? Cellular or Aerobic Respiration – • Aerobic respiration – respiration that requires oxygen produces 38 ATP • Ex. = cellular respiration CR - process that converts chemical energy (specifically glucose) into usable energy (specifically ATP) • A breaking part of metabolism • Occurs in the mitochondria • C6H12O6 + O2 + H2O H2O + CO2 + 38ATP (By the way, CR is much like burning fuel) Draw Mito Review: Photosynthesis: light E  chemical E Cellular Respiration: chemical E  usable E

  14. Now that the sugar is made, how do organisms turn it into usable E? • Student to board: What comes in and out of most living organisms? http://staff.tuhsd.k12.az.us/gfoster/standard/BCycles_files/cow_oxygencycle.jpg

  15. Also use text p. 232-234 What step requires O2? http://faculty.clintoncc.suny.edu/faculty/michael.gregory/files/bio%20101/bio%20101%20lectures/Cellular%20Respiration/cellul13.gif

  18. Are there organisms that live without oxygen? • YES (guess what they are?) • They get E via Anaerobic Respiration • Anaerobic respiration – respiration that does not require oxygen (produces 2 ATP) • Ex.= lactic acid FERMENTATION alcoholic FERMENTATIONS • The process in which glucose is converted into CO2 and H2O in the presence of oxygen, releasing much large amounts of ATP. . . Breathing to exchange O2 for CO2. http://www.everythingbio.com/glos/definition.php?word=aerobic%20respiration

  19. Summary, Writing Both Equations • Write equations on board! Chart in packet

  20. Why is Photosynthesis and CR so important? • Energy is stored in glucose during photosynthesis so that it can be torn apart during CR, the E released is used to make ATP Is photosynthesis or cellular respiration completed in plants? BOTH

  22. ATP Review • ATP = adenosine triphosphate • Organisms source of E • Quick, usable • The “whole” point of Photosynthesis and CR is to get ATP • ADP + P + Energy  ATP • ATP --> ADP + P + Energy • (D for di or 2, T for tri or three)

  23. P ADENOSINE TRIPHOSPHATE ADENOSINE DIPHOSPHATE ATP Continued Energy + +  We can use this ENERGY to run, walk, think play, sing, etc This molecule has LOTS of quick usable ENERGY stored in the bonds between the phosphates!!!

  24. Quiz on Photosynthesis 10/31/07 • What is the process that converts light energy to chemical energy? • A _________ is an organism that gets its energy directly from the sun, so that it can feed itself. • What are the two reactions in photosynthesis? • What gas is released during the first stage? • What gas is used in the second stage? • What organic molecule is made at the end of the second stage? • What color is not absorbed by plants? • What is the name of the hole in the leaf that allows gases in and out? • What are two environmental factors that affect the rate of photosynthesis. • What is the equation for photosynthesis? (If you are stuck, remember CR backwards)
