Photosynthesis Rate Practical
Investigating the effect of light intensity on the rate of photosynthesis, usually using pondweed (Elodea).
How do we measure the rate of photosynthesis in this experiment?
What is Photosynthesis Rate Practical?
"The photosynthesis practical is a common experiment used to determine how light intensity affects the speed of the reaction."
Which statement accurately describes light intensity practical at a GCSE level?
Which change would usually increase the rate of photosynthesis if light intensity is the limiting factor?
In the pondweed practical, what is often counted to estimate the rate of photosynthesis?
Select which change would usually increase the rate of photosynthesis if light intensity is the limiting factor?
Pondweed Method
Place a piece of pondweed in a test tube of water.
Move a light source to different distances from the pondweed.
Count the number of oxygen bubbles produced per minute.
To make the results more accurate, measure the volume of gas collected using a gas syringe.
