Photosynthesis
Most plants appear green because chlorophyll
does not absorb green light
which of the following activities happens within the stroma
The Calvin cycle produces sugars
Where do light dependent reactions take place?
Within the thylakoid membrane
Where in the chloroplast is chlorophyll found?
in the thylakoid membrane
What happens during photosynthesis?
autotrophs produce carbohydrates
Organisms that cannot make their own food and must obtain energy from external sources are called
heterotrophs
Organisms, such as plants, that make their own food are called
Autotrophs
where are photosystems I and II found?
in the thylakoid membrane
The Calvin Cycle takes place in the
stroma
Plants get the energy they need for photosynthesis by absorbing
sunlight
a student is collecting the gas given off from a plant in bright sunlight at a temperature of 27 degrees Celsius. The gas being collected is probably
oxygen
A granum is a
Stack of thylakoids
Energy is released from ATP when
a phosphate group is removed
What are three parts of an ATP molecule?
adenine, ribose, and three phosphate groups
what happens when chlorophyll is struck by sunlight?
the electrons in the chlorophyll molecule become energized.
plants gather energy with light- absorbing molecules called
pigments
what is the product of the Calvin cycle
high-energy sugars
What are the products of the light- dependent reactions?
ATP, NADPH, and oxygen gas
which of the following is not a part of an ATP molecule
chlorophyll
What is the role of NADP+ in photosynthesis?
electron carrier
The Calvin cycle is another name for the
light-dependent reactions
the stroma is the region outside the
thylakoids
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
oxygen
Which of the following organisms is a heterotroph?
mushroom
What makes certain molecules good electron carriers?
They can accept electrons and transfer most of their energy to another molecule.
