Bell Work 3/10
  • List the three major things needed for the process of photosynthesis.
  • Take a KWL sheet from the front cart
big ideas for today
Big Ideas for today
  • Explain where plants get the energy they need to make food
  • Describerole of ATP in cellular activities
  • State the overall equation for photosynthesis
  • Energy Forms:
    • Light
    • Heat
    • Electricity
    • Chemical Compounds
      • (Ex: Lighting a candle releases energy)
  • Cellular energy is stored in the form of Adenosine Triphosphate (ATP)
  • Compound structure:
how do cells use the energy
How do Cells use the Energy?
  • To use ATP a bond must be broken between the 2nd and 3rd Phosphates (P. 203)


Adenosine Diphosphate

  • Photosynthesis is a series of reactions that use light energy from the sun to convert (change) water and carbon dioxide into sugar and oxygen
  • Equation:

6H2O + 6CO2 ----------> C6H12O6+ 6O2

  • Plants use the sugars to make carbohydrates like starches

Bell Work 3/12
  • Write out the chemical equation for photosynthesis and label each part.
  • Take out your notes.
8 3 reactions of photosynthesis
8-3 Reactions of Photosynthesis
  • Photosynthesis occurs inside a Chloroplasts
  • Structures inside a Chloroplast:
    • Thylakoids: membrane that contains chlorophyll & other pigments that collect light
    • Granum: A stack of thylakoids
    • Photosynthesis has 2 parts:
      • 1 part uses light to produce ATP & NADPH
      • 1 part does not use light = CALVIN CYCLE; Cycle uses ATP & NADPH to make high-energy sugars (carbohydrates) (ex: glucose)
factors that affect photosynthesis
Factors that affect Photosynthesis
  • Water: not enough = slows down photosynthesis
  • Temperature: Best between 0 °C - 35 °C (32 °F - 95 °F)
  • Light intensity: more light = more photosynthesis
overall outcome
Overall Outcome
  • Photosynthesis is storing energy!!!
analyzing data
Analyzing Data
  • Look at the Analyzing Data section on page 213
  • Read both introduction paragraphs, look at the graph and then answer questions 1-4

Bell Work 3/13
  • Describe where both photosynthesis and cellular respiration take place within the cell.
  • Take out your notes from yesterday.
goals and objectives
Goals and Objectives


  • Compare and contrast the processes of photosynthesis and cellular respiration.
  • Photo. Equation vs Respiration Equation
  • Cellular Respiration Lab
9 1 cellular respiration p 221
9-1 Cellular Respiration (p. 221)
  • Takes place in the Mitochondria of the cell
  • Process that releases Energy


cellular respiration
Cellular Respiration
  • Other names this process goes by:
    • Krebs Cycle
    • Lactic Acid Fermentation
    • Glycolysis
  • Uses 2 Pathways:
    • Aerobic = Requires O2
    • Anaerobic = Does Not require O2
cellular respiration1
Cellular Respiration
  • It is a series of chemical reactions as well.
  • Equation:

C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (as ATP)


quick vs long term energy
Quick vs. Long Term Energy
  • Our cells stores small amounts of ATP so we can respond to sudden dangers (BURST OF ENERGY); only last a few seconds; cells build up lactic acid (feel the burn!!!)
  • Long-Term Energy requires cellular respiration to make a constant supply of ATP; Cells do this by using carbohydrates stores in the body (15-20 minutes); after that the body uses fat stores

Bell Work 3/18
  • In your own words, describe why leaves change color in the fall.
  • Find your Photosynthesis/Cellular Respiration comparison sheet we started making on Friday. (The folded piece of paper that we cut)
goals and objectives1
Goals and Objectives


  • Understand the processes taking place inside a plant cell when the leaves are changing color.


  • Correctly identify the names and colors of the accessory pigments
leaf pigments
Leaf Pigments
  • Carotene: Yellow Orange
  • Xanthophylls :Light yellow
  • Chlorophyll A :Blue green
  • Chlorophyll B: Yellow green
  • Anthocyanin: Red
  • The heavier the pigment the slower it migrates up the paper; The lighter the pigment the faster it migrates
Create a 2 part foldable comparing/contrasting Photosynthesis and Cellular Respiration
  • 1. Fold 1 time hamburger
  • 2. Cut half way to the crease
  • 3. Write “Photosynthesis” on bottom Left flap. Write “Cellular Respiration” on bottom Right flap.
  • 4. Starting on Left, Top, inside flap write the word “Function:”. Under it write “Location:”. Under it write “Reactants”. Under it write “Products:”. Under it write “Equation:”
Complete all needed information for both photosynthesis and cellular respiration
  • On the Front, left cover you will draw a large picture of a Chloroplast and label the following on it:
    • Thylakoids
    • Granum
    • Chlorophyll
  • On the Front, Right cover you will draw a large picture of a Mitochondria and label the following on it:
  • Cristae
chromatography lab
Chromatography Lab
  • Today we will be using Paper Chromatography to determine the specific types of leaf pigments found in a Spinach leaf.
  • There are several types of pigments found in leaves….
