Biology chapter 6 plant nutrition: The rate of photosynthesis of parts of individual leaves can be measured using a hand-held device as shown in the picture.
This apparatus allows air to flow through the transparent chamber that encloses part of the leaf. The apparatus measures the carbon dioxide concentration of the air entering and leaving the chamber.
Explain how the results from the apparatus can be used to calculate the rate of photosynthesis.
