**Location within Organism:**

* Chloroplasts (are, organelles)
* Chloroplasts (contain, chlorophyll)
* Chlorophyll (is, a pigment)
* Chlorophyll (absorbs, light energy)
* Chlorophyll (gives, plants, green color)
* Chloroplasts (have, thylakoids)
* Thylakoids (are, disc-shaped sacs)
* Thylakoids (are arranged, into, grana)
* Grana (are, stacks, of thylakoids)
* Chloroplasts (have, stroma)
* Stroma (is, fluid-filled space)
* Stroma (surrounds, thylakoids)

**Stages of Photosynthesis:**

* Photosynthesis (has, two, main stages)
* Stages (are, light-dependent reactions)
* Stages (are, light-independent reactions)
* Light-dependent reactions (occur, in, thylakoid membranes)
* Light-independent reactions (occur, in, stroma)

**Light-Dependent Reactions (Details):**

* Light-dependent reactions (require, light)
* Light-dependent reactions (absorb, light energy)
* Light energy (excites, electrons)
* Electrons (move, through, electron transport chain)
* Water (is split, in, light-dependent reactions)
* Water (releases, electrons)
* Water (releases, protons)
* Water (releases, oxygen)
* Electron transport chain (generates, ATP)
* Electron transport chain (generates, NADPH)
* ATP (is, energy currency)
* NADPH (is, electron carrier)
* ATP (is used, in, light-independent reactions)
* NADPH (is used, in, light-independent reactions)
* Protons (create, gradient)
* Proton gradient (drives, ATP synthesis)
* ATP synthase (produces, ATP)
* Photosystems (capture, light)
* Photosystem I (is, one, photosystem)
* Photosystem II (is, another, photosystem)
* Photosystem II (comes, before, Photosystem I)

**Light-Independent Reactions (Calvin Cycle Details):**

* Light-independent reactions (are called, Calvin Cycle)
* Calvin Cycle (does not require, light)
* Calvin Cycle (uses, ATP, from light reactions)
* Calvin Cycle (uses, NADPH, from light reactions)
* Calvin Cycle (uses, carbon dioxide)
* Carbon dioxide (is fixed, into, organic molecules)
* Carbon dioxide (combines, with, RuBP)
* RuBP (is, a five-carbon sugar)
* Rubisco (catalyzes, carbon fixation)
* Carbon fixation (forms, 3-PGA)
* 3-PGA (is converted, to, G3P)
* G3P (is, a three-carbon sugar)
* G3P (is used, to synthesize, glucose)
* G3P (is used, to regenerate, RuBP)
* Calvin Cycle (regenerates, RuBP)
* Calvin Cycle (is, a cyclical process)

**Factors Affecting Photosynthesis:**

* Light intensity (affects, rate, of photosynthesis)
* Carbon dioxide concentration (affects, rate, of photosynthesis)
* Temperature (affects, rate, of photosynthesis)
* Water availability (affects, rate, of photosynthesis)
* Pigment availability (affects, rate, of photosynthesis)

**Types of Photosynthesis (Variations):**

* C3 plants (perform, standard, photosynthesis)
* C3 plants (open, stomata, during day)
* C4 plants (have, specialized, leaf anatomy)
* C4 plants (minimize, photorespiration)
* CAM plants (open, stomata, at night)
* CAM plants (store, carbon dioxide, for day)

**Significance & Importance:**

* Photosynthesis (is, basis, of most food chains)
* Photosynthesis (produces, oxygen, for respiration)
* Photosynthesis (removes, carbon dioxide, from atmosphere)
* Photosynthesis (regulates, climate)
* Photosynthesis (is essential, for, life on Earth)

**Energy Transformation:**

* Light energy (is converted, to, chemical energy)
* Chemical energy (is stored, in, glucose)
* Organisms (use, glucose, for energy)
* Organisms (perform, cellular respiration, with glucose)
