The rate of photosynthesis

Question 1

give three examples of limiting factors in photosynthesis

Answer 1

Light, Carbon dioxide, temperature

Question 2

how does light become a limiting factor?

Answer 2

As the light level is raised, the rate of photosynthesis increases steadily-but only up to a certain point, after this the C02 or temperature needs to be increased

Question 3

how does CO2 become a limiting factor?

Answer 3

As the CO2 level is raised, the rate of photosynthesis increases steadily-but only up to a certain point, after this the light or temperature needs to be increased

Question 4

how does temperature become the limiting factor?

Answer 4

If the temperature is too low photosynthesis cannot occur, however if it is too hot 45’ or over then the enzymes become denatured and photosynthesis cannot occur
