1 Biology: Study for quiz! Today 12/4/2013Fermentation Quiz!Analyze (Define) Photosynthesis TermsIntroduce PhotosynthesisVOCAB QUIZ MONDAY DEC 9
2 After you turn in quiz, please work on defining terms.. Read the text for the definitions rather than the glossary! Some terms are NOT bold!Draw a picture to help you remember the word and definition!
3 *on back of your notesPeople didn’t know how photosynthesis worked until about the 1900’s. What are some possible ideas they may have had for how plants gained energy? (did they eat when no one was looking? Did they not need energy?.....)*
4 * tested plants to see if they were gaining their mass from the soil II. Early ExperimentsA. van Helmont- found that plant mass must be obtained through water and CO2 because the soil mass wasn’t changing* tested plants to see if they were gaining their mass from the soil*Measured mass of soil at beginning and end of growth period-no change*Water and CO2 are the only things plants are taking in, must be responsible for change!*
5 VIDEO!!! http://www.youtube.com/watch?v=pdgkuT12e14 B. Joseph Priestley discovered that plants release a substance that keeps a candle burning—oxygenC. Jan Ingenhousz discovered that plants only produced oxygen in the presence of lightD. Concluded that with light, plants convert CO2 and water to glucose and oxygen*

8 carbon dioxide + water → glucose + oxygen PHOTOSYNTHESIS SONG! ! III. PhotosynthesisA. 6CO2 + 6H2O → C6H12O6 + 6O2carbon dioxide + water → glucose + oxygenPHOTOSYNTHESIS SONG! !*
9 1. Chlorophyll a and b are plants main pigments-reflect green light B. Plants gather the sun’s energy with light absorbing molecules called pigments1. Chlorophyll a and b are plants main pigments-reflect green lighta. absorb red and blue wavelengthsb. absorb light=absorb energy
10 1. Thylakoids arranged in stacks called grana C. Inside chloroplasts there are stacks of thylakoids which contain chlorophyll (pigments) and proteins1. Thylakoids arranged in stacks called grana2. stroma is the area outside the thylakoidChloroplastSinglethylakoidstromaGranaLABEL YOUR CHLOROPLAST!!*
11 Light Energy (from sun) ChloroplastSugars & O2CO2 & H2O*
12 When plants grow, most of their added mass (start small and end up big) is made up of what? soil and carbon dioxide.water and carbon dioxide.oxygen and carbon dioxide.soil and oxygen.*
13 2. The raw materials required for plants to carry out photosynthesis are carbon dioxide and oxygen.oxygen and sugars.carbon dioxide and water.oxygen and water.*
14 3. The principal pigment in plants is chloroplast.chlorophyll.carotene.carbohydrate.*
15 4. The colors of light that are absorbed by chlorophylls are green and yellow.green, blue, and violet.blue, violet, and red.red and yellow.*
16 5. The 2 main products of photosynthesis produced by plants are: Carbon dioxide and waterGlucose and waterLight and oxygenGlucose and oxygen*
17 In van Helmont's experiment, most of the added mass of the tree came from soil and carbon dioxide.water and carbon dioxide.oxygen and carbon dioxide.soil and oxygen.*
18 2. The raw materials required for plants to carry out photosynthesis are carbon dioxide and oxygen.oxygen and sugars.carbon dioxide and water.oxygen and water.*
19 3. The principal pigment in plants is chloroplast.chlorophyll.carotene.carbohydrate.*
20 4. The colors of light that are absorbed by chlorophylls are green and yellow.green, blue, and violet.blue, violet, and red.red and yellow.*
21 5. The 2 main products of photosynthesis produced by plants are: Carbon dioxide and waterGlucose and waterLight and oxygenGlucose and oxygen*
22 Light Energy (from sun) ChloroplastSugars & O2CO2 & H2O*
23 D. NADPH- energy carrier(nicotinamide adenine dinucleotide phosphate) 1. Sunlight reaches the chlorophyll, causing electrons to gain energy *excited electrons2. NADP+ carries 2 high energy electrons and one H+, becomes NADPHNADP e- = NADPH*Like using a special pan to carry hot coals!IV. Light Dependent Reactions (happen in thylakoid)1. Water is broken up into O, H+, and electrons-oxygen is released2. Chlorophyll absorbs sunlight (energy)-makes electrons “energetic” ,they move down the electron transport chain*
25 B. ADP is converted to ATP, NADP+ is converted to NADPH Inside of thylakoid is positively charged because of all the H+, these move through the ATP synthase and reattach P to ADP to form ATP.B. ADP is converted to ATP, NADP+ is converted to NADPHLight dependent Reactions: *Charge up the batteries!In OutH2O O2ADP ATPNADP+ NADPH*happens in thylakoid, because it needs chlorophyll*Now chloroplast has highly charged molecules ATP and NADPH to help make sugar!*
27 Summarize what happens during the Light Dependent Reactions!
28 V. Light Independent reactions- Calvin Cycle Takes place in stroma-because it doesn’t need the pigmentsUses the energy stored in ATP and NADPH to make high-energy sugars!C. End result of Calvin Cycle:In OutATP ADPNADPH NADP+CO2 glucoseD. Uses 6 Carbon Dioxide molecules to make one glucose molecule (C6H12O6)*
29 Summarize what occurs in the Calvin Cycle or Light Independent Reaction
30 Bellringer: Label Chloroplast Bio: Vocab Quiz Moved to Tues! :) Please grab bellringer from front of room and start working on it… Try it without your notes! See what you remember!Today: 12/9/13Bellringer: Label ChloroplastExplain what happens during photosynthesisExplain why leaves change colorPhotosynthesis quiz end of this week!
31 Label the stages of Photosynthesis. Label the inputs and outputs! *
33 VI. Factors Affecting Photosynthesis A. Water loss can slow or even stop photosynthesis.1. Stomata are openings on the outside of leaves that allow for CO2 to enter and O2 to leave, usually closed so less water lostB. Temperature must be between 0°C and 35°C.C. If you increase light intensity, you will increase the rate of photosynthesis.*

37 Biology: Pick up a lab papers off stool in front! Dec 11, 2013Biology: Pick up a lab papers off stool in front!Read the entire thing. You do not have to start doing the pre-lab questions right now.*You will do them during the lab* You will be having a lab quiz before we start the lab… so read!!!*
38 LAB QUIZ—You can use your lab to answer! What pigment shows a red color?How are you going to get the plant to stain on the paper?What type of solution are you going to place your filter paper in (in the beaker)How long do you have to wait for your pigments to separate?What is the process called when you use a solvent to separate out plant pigments? (you are doing this today, starts with a C)
39 Objective for Today:Analyze paper chromatography and identify the different pigments found in plants.
40 Photosynthesis begins when light is absorbed by pigments in the plant cell. One technique for separating and identifying these pigments is paper chromatography. In paper chromatography, solvent moves up the paper carrying with it dissolved substances-in this case plant pigments. The pigments are carried along at different rates because they are not equally soluble in the solvent and are attracted in different degrees into the paper.Many green leaves contain pigment colors that are not seen until autumn because they are hidden by the chlorophyll. A few plants have leaves that are red, orange, or yellow all year long.*
