Photosynthesis takes place in the ______________________ of plants.
Light dependent reactions and the Calvin Cycle
What are the two phases that photosynthesis takes place in?
Plants have ________________ - molecules that absorb specific wavelengths of sunlight.
___________________ is the green pigment in plants that is used for photosynthesis. It is stored in ____________________.

2. Some of this energy is used to change ADP to ATP.
3. Energy is also used to split water into hydrogen and oxygen.
4. Hydrogen is sent to the light-independent reactions and oxygen is given off as a waste.
What are the steps of light dependent reactions?
__________________ is carried to the light-independent reactions by NADP.
______________ _____________ discovered the reactions of light independent reactions.

Light ___________________ reactions take place in the ____________ of the chloroplasts.
Light __________________ reactions take place on the __________________ _________________ of the chloroplasts.
-a molecule present in all living cells and acting as a energy source for metabolic processes
-a substance involved in energy metabolism formed by the breakdown of adenosine triphosphate
-an enzyme that catalyzes the synthesis of ATP from ADP and phosphate
-a class of light-absorbing pigments used in photosynthesis
-a stack of thylakoids in a chloroplast
-the initial reactions in photosynthesis, including the absorption of light by photosynthesis I and II, the passage of electrons along the electron transport chains, the production of NADPH and O2 , and the synthesis of ATP through chemiosmosis
-the conversation of light energy into chemical energy stored in organic compounds
-in plants, a compound that absorbs light and impacts color
-in plants, the solution that surrounds the thylakoids in a chloroplast
-a biochemical pathway of photosynthesis in which CO2 is converted into carbohydrates
-a plastid containing chlorophyll; the site of photosynthesis
