Study Notes
Photosynthesis and Life
- Photosynthesis is crucial for sustaining life on Earth.
- Photosynthetic organisms produce oxygen and make their own food, sustaining themselves and other organisms.
Sun's Energy
- The sun releases energy in various wavelengths, including visible light.
- Visible light is perceived as colors, ranging from violet to red.
Photosynthesis in Chloroplasts
- Photosynthesis occurs in chloroplasts, found in mesophyll cells inside leaves.
- Chloroplasts contain stacks of thylakoids called grana, which are involved in the light-dependent reactions of photosynthesis.
Carbon Fixation Pathways
- Plants utilize different carbon fixation pathways, including C3, C4, and CAM pathways.
- C4 pathway occurs in plants adapted to hot, dry environments, reducing photorespiration to conserve water.
- CAM pathway occurs in succulent plants like cacti, allowing them to absorb carbon dioxide at night and fix it during the day to conserve water.
