Here are key facts about photosynthesis as (subject, predicate, object) triples:

**Basic Definition & Process:**
- (Photosynthesis, is, biological process)
- (Photosynthesis, converts, light energy into chemical energy)
- (Plants, perform, photosynthesis)
- (Algae, perform, photosynthesis)
- (Cyanobacteria, perform, photosynthesis)

**Inputs & Outputs:**
- (Photosynthesis, requires, sunlight)
- (Photosynthesis, requires, carbon dioxide)
- (Photosynthesis, requires, water)
- (Photosynthesis, produces, glucose)
- (Photosynthesis, produces, oxygen)
- (Photosynthesis, releases, oxygen as byproduct)

**Location & Structure:**
- (Photosynthesis, occurs in, chloroplasts)
- (Chloroplasts, contain, chlorophyll)
- (Chlorophyll, gives, green color to plants)
- (Thylakoids, are, site of light reactions)
- (Stroma, is, site of dark reactions)

**Two Main Stages:**
- (Light reactions, occur in, thylakoids)
- (Calvin cycle, occurs in, stroma)
- (Light reactions, produce, ATP)
- (Light reactions, produce, NADPH)
- (Calvin cycle, uses, ATP)
- (Calvin cycle, uses, NADPH)
- (Calvin cycle, fixes, carbon dioxide)

**Chemical Equation:**
- (6CO2 + 6H2O + light energy, yields, C6H12O6 + 6O2)

**Importance:**
- (Photosynthesis, provides, oxygen for atmosphere)
- (Photosynthesis, forms, base of food chains)
- (Photosynthesis, removes, carbon dioxide from atmosphere)
