Photosynthesis Experiments
Biology: Cambridge International GCSE Supplement, topic 6.1.6
Measuring the Rate of Photosynthesis
The rate that pond weed produces bubbles indicates the rate of photosynthesis. The bubbles released are oxygen, a waste product of photosynthesis.
Investigating Photosynthesis Rates
Light intensity is not the only factor that can affect the rate of photosynthesis. Other factors that you might want to investigate are:
Temperature
Carbon dioxide concentration
Test yourself on Photosynthesis Experiments
Light intensity can affect the rate of which process in plants such as pondweed?
The bubbles used to measure the rate of photosynthesis in pondweed are full of which gas?
Which of these is NOT a variable that should be controlled when testing the effect of light intensity on plant photosynthesis?
