Measuring the Rate of Photosynthesis

From A to B

• light intensity does not affect the rate of P/S

• as light intensity increases the rate of P/S increases

• as the light intensity increases the rate of P/S decreases

From B to C

• carbon dioxide in the air become the limiting factor

• as light intensity increases the rate of P/S increases

• as the light intensity increases the rate of P/S decreases
