When light strikes an object its is either reflected, ________ or ________.

Substances that ________ visible light are called pigments

Chlorophyll a, absorbs red and ________ light

The light which can't be absorbed by chlorophyll a is absorbed by chlorophyll b and ________.

Chlorophyll b and carotenoids are also called ________ pigments. They pass the photon energy to chlorophyll a, ________ the spectrum that can effectively drive photosynthesis

The interior of the chloroplast consists ofa) flattened sacs called ________, which in places are ________ into structures called ________.b) ________ (fluid) outside the ________.

Grana are stacks of thylakoid membranes containing ________.

The liquid interior of chloroplast is called ________.

The light dependent phase occurs in the ________ membranes of a chloroplast.The light independent phase occurs in the ________ of chloroplasts

In photosynthesis, Carbon dioxide from the air provides carbon and oxygen as raw materials. Carbon is fixed in the Light ________ phase.

The ________ in green plants are protein complexes used to harvest light energy so it can be converted into ________ energy in the ________ of the chloroplasts.

During photosynthesis, chemical energy is stored in - ________ and NADpH.NADpH is ________ Adenine ________ ________  

When chlorophyll molecules absorb light, an electron is excited to a ________ level. This electron “________” must be filled.

In Electron transport chain: Each electron is passed from one electron carrier to another; ________ energy as it goes. This energy is used to pump ________ ions across the thylakoid membrane.

ATP synthase catalyzes the production of ATP from ________ and inorganic ________.

Photolysis of water: In noncyclic ________, the electrons lost to the electron transport chain are replaced by splitting a water molecule (photolysis) releasing oxygen gas and hydrogen ions. 

Flow of H+ back across the membrane is coupled to ATP synthesis by ________.

Light Dependent Phase:In the thylakoid, light reactions use the energy of ________ to split water molecules. ________ is waste and the ________ ions are used to make ________ and NADpH. These are discharged into the ________. 

The ATP and NADpH are used in the ________ Cycle.

During the Calvin Cycle, the enzyme ________ does the work of reducing carbon dioxide from the atmosphere.

The carbohydrates produced during the Calvin cycle can be stored to provide energy for use at a later stage. Carbon fixation does not require ________ to proceed. However, it does require the ________ and ATP that are supplied by the light dependent phase.

The ________ pigment loses its electrons after other pigments transfer energy to it.
