Revision Notes
Key Points
- Photosynthesis is the process by which plants and some other organisms use the energy from sunlight to convert carbon dioxide and water into glucose and oxygen.
- The overall equation for photosynthesis is: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
- Requirements for photosynthesis include chlorophyll, carbon dioxide, water, and sunlight.
- Photosynthesis takes place in the chloroplasts of plant cells, specifically in the thylakoid membranes.
Definition
Photosynthesis is the process by which plants and some other organisms use the energy from sunlight to convert carbon dioxide and water into glucose and oxygen.
Reaction of Photosynthesis
The overall equation for photosynthesis is:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
Requirements for Photosynthesis
For photosynthesis to take place, the following are required:
- Chlorophyll (a green pigment found in chloroplasts)
- Carbon dioxide (CO₂)
- Water (H₂O)
- Sunlight (or other light source)
Location of Photosynthesis
Photosynthesis takes place in the chloroplasts of plant cells, specifically in the thylakoid membranes.
