Here are key facts about photosynthesis as subject-predicate-object triples:

**Basic Definition:**
- Photosynthesis, is, a biological process
- Photosynthesis, converts, light energy into chemical energy
- Photosynthesis, occurs in, plants
- Photosynthesis, occurs in, algae
- Photosynthesis, occurs in, certain bacteria

**Location:**
- Photosynthesis, takes place in, chloroplasts
- Chloroplasts, contain, chlorophyll
- Chlorophyll, absorbs, light energy
- Chloroplasts, have, thylakoids
- Chloroplasts, have, stroma

**Overall Equation:**
- Photosynthesis, requires, carbon dioxide
- Photosynthesis, requires, water
- Photosynthesis, requires, light energy
- Photosynthesis, produces, glucose
- Photosynthesis, produces, oxygen
- Photosynthesis, follows, 6CO2 + 6H2O + light energy → C6H12O6 + 6O2

**Two Main Stages:**

**Calvin Cycle:**
- Calvin cycle, fixes, carbon dioxide
- Calvin cycle, uses, ATP
- Calvin cycle, uses, NADPH
- Calvin cycle, produces, glucose
- Calvin cycle, involves, RuBisCO enzyme
- RuBisCO, catalyzes, carbon fixation

**Importance:**
- Photosynthesis, provides, food for organisms
