What 4 factors affect the rate of photosynthesis?
- temperature
- carbon dioxide concentration
- light intensity
- chlorophyll concentration
What can damage chlorophyll concentration?
- disease (TMV)
- environmental stress
- lack of nutrients
- damaged chloroplasts
How can farmers artificially create optimum conditions?
- greenhouses
- artificial light
- pump in CO2 with a paraffin heater
- fertiliser (for minerals)
How do greenhouses help plants?
they trap the sun's heat ad prevent diseases getting in
How can the temperature being too high damage the rate of photosynthesis?
