What to Focus On
- Life processes are maintenance functions that must continue even during rest or sleep.
- Living structures are organised and must be continuously maintained to prevent breakdown.
- Molecular movement is the fundamental indicator of life — even if not visible externally.
- Autotrophs make food via photosynthesis; heterotrophs depend on others for food.
- Photosynthesis equation: 6CO₂ + 12H₂O → (Chlorophyll+Sunlight) → C₆H₁₂O₆ + 6O₂ + 6H₂O
- Three events in photosynthesis: light absorption, light-to-chemical energy conversion + water splitting, CO₂ reduction.
- Respiration is a cellular process that releases energy from food; it is different from breathing.
- ATP is the energy currency of cells; produced during respiration and used for all cellular activities.
- Glycolysis occurs in the cytoplasm for all organisms; pyruvate is the product.
Common Mistakes to Avoid
Plants only perform photosynthesis, not respiration
Photosynthesis and respiration are opposite processes that cancel each other out
Fermentation and anaerobic respiration are completely different processes
Memory Tips
Life Processes — Nutrition, Respiration, Transportation, Excretion
Photosynthesis — Reactants, Products, and Conditions
Three Events of Photosynthesis — Absorption, Conversion/Splitting, Reduction
Stomata — Opening and Closing Mechanism via Guard Cells
