- Unit B8
- Unit 1
- Photosynthesis
- Endothermic reaction
- Can be seen in a plant by the gas given off as a by-product
- Enzyme controlled reaction
- Leaf adaptations
- Veins bring plenty of water and remove photosynthesis by products
- Air spaces allow carbon dioxide to get to cells
- Guard cells regulate gas exchange
- Chlorophyll in chloroplasts absorb light
- Thin leaves so gas diffusion distance is short
- leaves move to face sun
- Photosynthesis
- Unit 2
- Rate of Photosynthesis
- Factors
- Wavelengths of light
- Temperature
- As the temperature increases so does photosynthesis
- This is because more energy is provided for the reaction
- As the temperature increases so does photosynthesis
- Light intensity
- As it increases so does the rate of photosynthesis
- Because more energy is provided for thee reaction
- As it increases so does the rate of photosynthesis
- Dissolved carbon dioxide
- As the concentration increases so does the rate of photosynthesis
- If a factor is in limited supply it is known as a limiting factor
- Factors
- Rate of Photosynthesis
- Unit 3
- How plants use glucose
- Any glucose made in photosynthesis is stored as starch because it's insoluble in water and wont affect the water balance of the plant
- Starch storage
- Leaf cells
- Tubers and bulbs etc.
- Plant and algal cells use glucose for respiration
- How plants use glucose
- Unit 4
- Making the most of photosynthesis
- Greenhouses
- Hydroponic growing system
- Growing plants without soil
- Propane Burner
- Burning hydrocarbons to produce carbon dioxide
- Thermostatically controlled vents
- open if the temperature is too high
- Artificial lighting
- Allows for photosynthesis 24 hours a day
- Irrigation system
- Brings water to somewhere there isn't
- Hydroponic growing system
- Greenhouses
- Making the most of photosynthesis
- Unit 1
