1
Q
What three things slow down the rate of photosynthesis?
A
Lack of light, low temperature and too little carbon dioxide
2
Q
How does the lack of light affect the rate of photosynthesis?
A
Light provides energy for the process
3
Q
How does low temperature affect the rate of photosynthesis?
A
If it to too cold the enzymes will not work effectively which slows down the rate of photosynthesis
4
Q
How does too little carbon dioxide affect the rate of photosynthesis?
A
Carbon dioxide is needed for photosynthesis.
5
Q
What is the independent variable?
A
The one being tested e.g. concentration of CO2
6
Q
What is the dependent variable?
A
The one you measure
7
Q
If you are testing the concentration of CO2, what variables have to be controlled?
A
Light, temperature and type of plant
