Calculating Rates of Photosynthesis
In exams, you may be asked to calculate the rate of photosynthesis from experimental data.
If 20 bubbles are produced in 2 minutes, what is the rate per minute?
What is Calculating Rates of Photosynthesis?
"Photosynthesis rate calculation is the process of using time and volume data to determine the speed of the reaction."
In the pondweed practical, what is often counted to estimate the rate of photosynthesis?
GCSE Biology: In the pondweed practical, what is often counted to estimate the rate of photosynthesis?
A graph of photosynthesis rate rises and then levels off as light intensity increases. What does the flat section show?
Rate Math
Rate = Volume or Number of Bubbles / Time.
Always check the units required (e.g., bubbles/min or cm³/hour).
Use the inverse square law when distance is involved.
Rate calculations are common in Paper 1 Biology exams.
