Photosynthesis – Q&A for Quick Revision (Higher Plants)
What is Photosynthesis?

 Plants use sunlight, CO2, and water to produce glucose and oxygen.
2. Main site of Photosynthesis?

 Chloroplasts in palisade mesophyll cells.
3. Overall Photosynthesis equation:

 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2
4. Difference between Light and Dark Reactions:
Light Reaction:

 Place: Thylakoid membrane
 Requirement: Light
 Products: ATP, NADPH, O2
Dark Reaction (Calvin Cycle):

 Place: Stroma
 Requirement: ATP, NADPH
 Product: Glucose (C6H12O6)
5. Factors affecting Photosynthesis:

 Light intensity
 CO2 concentration
 Temperature
 Water availability
6. Role of Chlorophyll:

 Absorbs sunlight and provides energy for the process.
7. Oxygen release in Photosynthesis:

 Water splits into hydrogen and oxygen; oxygen is released into the atmosphere.
