- 1Equation for photosynthesiscarbon dioxide+water----------> (+light energy) glucose + oxygen
- 2What is photosynthesisLight energy being transferred to chemical energy by plants
- 3Process for photosynthesis1. Carbon dioxide taken in by the leaves
2. Chlorophyll traps the light energy needed for photosynthesis
3. Energy is used to convert the carbon dioxide and water into glucose - 4Limiting factorsPlants grow best when the have enough, light, carbon dioxide, water and kept at suitable temperatures.
- 5LightLack of light would slow down process as provides energy might be limited by shade
- 6ColdEnzymes do not work effectively and slow down the rate of photosynthesis
- 7Independent VariableOne being tested
- 8Dependant variableOne you measure
- 9How plants use glucoseConverted into insoluble starch for storage
Used for respiration
Converted into fats and oils for storage
used to produce cellulose strengthens cell walls
Used to produce proteins - 10Mineral ionsPlants also need these absorbed from water by algae or soil by plants nitrate ions used to produce protein
- 11Distribution of organismsAffected by:
temperature, availability of nutrients, amount of light, availability of water, availability of oxygen, availability of carbon dioxide.
