what object inside a plant is a flattened membrane sac inside the chloroplast, used to convert light energy to chemical energy.
Thylakoids
The conversion of light energy to chemical energy that is stored in glucose or other organic compounds; occurs in plants, algae, and certain prokaryotes. This is called what?
Photosynthesis
Stomata
What are the pores on the leaf where O2 exits and CO2 enters
Stomata
What is the The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water.
Stroma
Chlorophyll
What is the name of the green pigment located in membranes within the chloroplasts of plants and algae. It participates directly in the light reactions, which convert solar energy to chemical energy.
Chlorophyll
The classification of reactions of photosynthesis that depend upon energy from light to produce ATP.
Light dependent
The first of two major stages in photosynthesis (preceding the Calvin cycle). These reactions, which occur on the thylakoid membranes of the chloroplast and convert solar energy to the chemical energy of ATP and NADPH, releasing oxygen in the process are called?
Light Reactions
The second of two major stages in photosynthesis (following the light reactions, could be one of three names) is called?
Calvin cycle/Dark Reaction/Light Independent
Which of the following statements is a correct distinction between autotrophs and heterotrophs?

a) Autotrophs, but not heterotrophs, can nourish themselves beginning with CO2 and other nutrients that are inorganic.
b) Only heterotrophs require oxygen.
c) Cellular respiration is unique to heterotrophs

Autotrophs, but not heterotrophs, can nourish themselves beginning with CO2 and other nutrients that are inorganic.
Which of the following DOES NOT occur during the Calvin cycle?

a) release of oxygen
b) generation of the CO2 acceptor
c) oxidation of NADPH
d) consumption of ATP

Release of Oxygen
ATP
The light reactions of photosynthesis supply the Calvin cycle with
ATP
The chemical equation for photosynthesis.
6CO2 + 6H2O → C6H12O6 + 6O2

Photosynthesis requires carbon dioxide and water for the production of sugar and oxygen.

Chloroplast

Chloroplasts use energy from light to transform carbon dioxide and water into sugar and oxygen.
Where does photosynthesis take place?
Chloroplast

Chloroplasts use energy from light to transform carbon dioxide and water into sugar and oxygen.

The two molecules are produced by the light reactions and used to power the Calvin cycle.
ATP and NADPH

ATP and NADPH are both products of the light reactions and are used to power the Calvin cycle.

Provides electrons for the light reactions?
H2O

Electrons are stripped from water in the light reactions of photosynthesis. Light provides the energy to excite electrons.

Provides the carbon atoms that are incorporated into sugar molecules in the Calvin cycle.
Carbon dioxide (CO2)

Carbon dioxide provides the carbon atoms that are incorporated into sugars in photosynthesis.
.

Transports electrons from the light reactions to the Calvin cycle.
NADPH

NADPH is an electron carrier that picks up electrons in the light reactions and releases them in the Calvin cycle. An electron transport chain conveys electrons from one photosystem to the other within the light reactions.

Where does the Calvin Cycle takes place?
The Calvin cycle is a complex series of chemical reactions carried out in the stroma.
Guard cells

Guard cells
ADP
Adenosine Diphosphate
ADP
