STUDY
PLAY
Which makes its own food using light energy from the sun? mushroom,amoeba,leopard, or oak?
Oak
True or False: Is a sunflower a heterotroph?
True
T or F: Autotrophs consume carbohydrates.
False
T or F: Pigments are where plant's gather energy with light-absorbing minerals
True
T or F: Sunlight is an important ingredient in photosynthesis
True
T of F: Chlorophyll absorbs green light
False
A granum is: a stack of thylakoids or chloroplasts
A stack of thylakoids
T of F: The stroma is outside of the chloroplasts
False
Where is the chloroplast found? In the thylakoid membrane or in the ATP
In the thylakoid membrane
T or F: Chlorophyll is part of the ATP molecule
False
When chlorophyll is struck by light, does it become energized or deenergized?
It becomes energized
What is the role of the NADP+ molecule? pigment or electron carrier?
Electron Carrier
T or F: Electron carriers can accept electrons and transfer most of their energy to another molecule
True
T or F: Electron carriers needed for transporting electrons from one part of the chloroplast to another
True
A student is collecting the gas given off from a plant in bright sunlight at a temperature of 27°C. The gas being collected is probably: carbon dioxide,hot breath, or oxygen.
Oxygen
T/F: Photosynthesis uses sunlight to convert water and carbon dioxide into oxygen and high-energy sugars?
True
T/F: Nitrogen is found in the overall reaction for photosynthesis
False
T/F: In the overall equation for photosynthesis, six molecules of carbon dioxide and six molecules of water result in a molecule of sugar and six molecules of glucose.
False
T/F: Energy is released from ATP when a phosphate group is added.
False
Where do the light-dependent reactions take place? In the thylakoid membrane or inside the nucleus?
In the thylakoid membrane
T/F: ATP, NADPH, and oxygen gas arethe products of the light-dependent reactions
True
Is this a step in the light-dependent reactions? ATP and NADPH are used to produce high-energy sugars?
Yes
T/F: H+ ions are released as water splits during light-depenndent actions.
True
T/F: Thylakoid membranes are NOT where photosystems I and II are found.
False
T/F: The Calvin Cycle produces sugars
True
Which pathway represents the flow of electrons during photosynthesis? O2 ® ADP ® Calvin cycle
or H2O ® NADP+ ® Calvin cycle?
H2O ® NADP+ ® Calvin cycle
T/F: Light-dependent reactions are another name for photosynthesis.
True
T/F: The stroma is where the Daril cycle takes place/
False
T/F: High energy sugars are NOT the product of the Calvin Cycle.
False
T/F: Used ATP is discarded by the cell as waste
False
Where does the Calvin Cycle take place? Stroma, or lysosomes?
Stroma
T/F: No sugars will be produced If carbon dioxide is completely removed from a plant's environment, what would you expect to happen to the plant's production of high-energy sugars
True
T/F: The rate of the Calvin Cycle increases and then levels off If you continue to increase the intensity of light that a plant receives
False
T/F: Organisms that make their own food are called autotrophs.
True
T/F: Organisms that cannot make their own food and must obtain energy from external sources are called ? Plants or heterotrophs?
Heterotrophs
T/F: Chloroplasts are the organelle of photosynthesis
True
T/F: Thylakoids are the sub-organelles which are the site of the Calvin Cycle
False
T/F: Photosynthesis is NOT important to human life.
False
T/F: Plants make their own food by mating with each other.
False
Does NADPH hold chemical energy?
Yes
T/F: Glucose is the product of photosynthesis.
True
T/F: Photosynthesis makes and uses ATP/
True
T/F: Energy is th emost important chemical reaction ever
False
T/F: Photosynthesis does not have a series of chemical reactions
False
T/F: Photosynthesis makes up 99% of all food for life
True
T/F: Only four groups of organisms make up phototsynthesis
False
T/F: Water and carbon dioxide molecules are reactants in photosynthesis
True
T/F: Life requires photosynthesis for fuel and for oxygen to burn fuel.
True
Phototsynthesis uses water T or F?
True
Sunlight is needed for photosythesis? T or F?
True
