Work out photosynthesis rate instantly with clear inputs, formula shown and shareable results.
Converts collected oxygen volume into a leaf-area-normalised photosynthesis rate, including the micromole units used in gas exchange work.
Photosynthesis rate
Rate = oxygen volume / (leaf area x time); micromoles = volume (mL) / 22.4 x 1000 at standard temperature and pressure
It removes plant size from the comparison, isolating the physiological rate.
No. Measured evolution is net of respiration, so gross photosynthesis is higher.
