The Rate Of Photosynthesis Flashcards
Why will the rate eventually plato as light intensity gets to a certain point
It will now be temperature of CO2 level that is the limiting factor
How can you change light intensity in a lab
Moving a lamp closer or further from the plant
What temperature do enzymes denature
45°c
What is the equation for light intensity ( inverse square law )
1/d^2
What does the inverse square law mean
If you half the distance the light intensity will be 4 times greater
What is the most common way to artificially grow plants
In a greenhouse
What do greenhouses do
Trap suns heat and make sure the temperature doesn’t become limiting
Protect plants from pests
How can a farmer maintain photosynthesis in a greenhouse during winter
Using a heater to keep temperature level
How can a farmer maintain photosynthesis in a greenhouse in summer
Use ventilation and shading to cool it down
How can farmers make photosynthesis happen at night
Use artificial light
What does a paraffin heater do
Increase carbon dioxide concentration
Why do farmers supply plants with fertilisers in greenhouses
To provide minerals needed for growth
