What to Focus On

  • Photosynthesis converts light energy into chemical energy.
  • It occurs in chloroplasts of green plants.
  • Raw materials: CO₂ and H₂O; Products: Glucose and O₂.
  • Provides food for almost all living organisms.
  • Releases oxygen essential for respiration.
  • Reduces greenhouse gases by absorbing CO₂.
  • Chloroplasts have a double membrane and internal thylakoid system.
  • Grana are stacks of thylakoids; stroma is the fluid surrounding them.
  • Pigments in thylakoids trap light energy.

Common Mistakes to Avoid

Oxygen released during photosynthesis comes from carbon dioxide (CO₂).

Dark reaction happens only in the dark or requires darkness.

Chlorophyll is the only pigment involved in photosynthesis.

Memory Tips

Definition of photosynthesis: process by which green plants use sunlight to make food from CO₂ and H₂O, releasing O₂.

Overall photosynthesis equation: 6CO₂ + 12H₂O → C₆H₁₂O₆ + 6H₂O + 6O₂

Chloroplast structure: outer membrane, inner membrane, stroma, thylakoids, grana, lamellae

Photosystems: PSII (P680) and PSI (P700)
