The following equation shows the relationship between the distance of a light source and the light intensity: .
If the distance between the plant and the light source halves, what happens to the rate of photosynthesis?
What gas is produced by plants when they photosynthesize?
The diagram shows a simple set of the equipment used to investigate the effect of light intensity on the rate of photosynthesis in pondweed.
Using this equipment, how can the rate of photosynthesis be measured?
In this experiment, what is the independent variable?
