- Heterotrophs- Organisms that must obtain energy from the foods they consume
- Chloroplast- an organelle that contains chlorophyll and in which photosynthesis takes place
- Pigment- light-absorbing molecules that plants use to gather the suns energy, and any various molecule that is capable of accepting one or two electrons from one molecule and donating them to another in the process of electron transport
- Chlorophyll- a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis
- ATP- a chemical compound that cells use to store and release energy]]> 2021-05-12 16:27:50 UTC https://padlet.com/2024blackj/hwdtw8e9iesp1lfd/wish/1518204755 Definitions; Pt2 2024blackj https://padlet.com/2024blackj/hwdtw8e9iesp1lfd/wish/1518283067 - NADPH - electron-carrier molecule used in the Calvin Cycle
- Electron Carrier Molecule- Any various molcules that are capable of accepting other electrons and using them in the electron transport
- Thylakoid- number of flattened sacs inside a chloroplast
- Granum- the stacks of thylakoid embedded in the stroma of a chloroplast
- Stroma- the fluid interior of a chloroplast
- Photosystem l- transfers electrons across the thylakoid membrane
- Photosystem ll- biological mechanism in plants by which chlorophyll absorbs light for photosynthesis
- ATP synthesis- produces ATP LR

  • Under which condition will a plant grow better: under red light, or under green light? Explain.- red light because plants reflect green, they don’t absorb it
  • What gas do plants take in?  - carbon dioxide
  • What gas do plants release?- oxygen
  • What is the equation for photosynthesis in words?- water + light + carbon dioxide → sugar + oxygen
  • What is the equation for photosynthesis in symbols?- 6H2O + light + 6CO2  → C6H12O6 + 6O2
  • What are the reactants of the light-dependent reaction? - The reactants are water ADP, NADP+, water, light
  • What are the products of the light-dependent reaction? - The products are oxygen, ATP, and NAPDH
  • Where does the light-dependent reaction take place? - The light-dependent reactions take place in the chloroplasts within the thylakoid membrane
  • What are the reactants of the light-independent (Calvin Cycle) reaction? - The reactants are ATP and NAPDH
  • What are the products of the light-independent (Calvin Cycle) reaction? - The products are high-energy sugars from carbon dioxide and water.
  • Where does the light-independent reaction (Calvin Cycle) take place? - It takes place in the stroma.
  • How are the light-dependent and light-independent reactions interconnected? -  The ATP and the NADPH that were made in the light-dependent reactions are used in the light-independent reactions to make high-energy sugars.

During the light-dependent reactions, what makes the inside of a thylakoid become more positively charged? The inside becomes more positively charged because of the more positively charged hydrogen ions(H+) entering it.
    14. If carbon dioxide was removed from a plant’s environment, what would happen? - MD The plant wouldn’t be able to start the Calvin Cycle.
    15. List the three parts of an ATP molecule. - MD Adenine, Ribose, 3 Phosphate Groups
    16. When is energy released from ATP? - MD Energy is released by breaking the chemical bond between the 2nd and 3rd phosphates.
    17. What is the difference between ADP and ATP? - MD ATP has 3 phosphate groups and ADP has only 2 phosphate groups.
    18. The bond that is broken in an ATP molecule is between which two parts of the ATP? - MD 2nd and 3rd phosphate groups. 
    19. Why do most plants appear green? - MD Because they absorb blue-violet and red.
    20. When light strikes a chlorophyll molecule, what happens to the electrons? - raises the energy levels, and makes photosynthesis scream “go”
    21. What makes a molecule like NADP+ an “electron carrier”? - holds 2 high-energy electrons and a hydrogen ion, uses them for energy for the Calvin Cycle
    22. Why does a plant allow a candle under a jar to burn longer? - it produces oxygen that allows the flame to stay lit
    23. Photosynthesis cannot begin at all unless what strikes a plant? -- light
    24. What is the control variable in any scientific experiment? - the variable that remains unchanged

    Took a lit candle, placed a glass jar over it
    What happened? 
    Placed a mint plant in the jar with the candle
    The candle continued to burn…. Why?
    - The mint was producing oxygen to keep the flame burning.
