Factors of Photosynthesis

Question 1

what are the potential limiting factors for photosynthesis

Answer 1

light
carbon dioxide
water
temperature
chlorophyll

Question 2

what is important to remember about water

Answer 2

it won’t effect photosynthesis because too important and would kill the plant if low availability

Question 3

what does increasing light intensity look like on a graph for rate of photosynthesis

Answer 3

on y axis is rate of photosynthesis
on x is light intensity

as it increases it moves up straight line but plateaus because CO2 or temperature limits the rate

Question 4

what is the equation for light intensity

Answer 4

1/distance^2

Question 5

what does increasing carbon dioxide look like on a graph for rate of photosynthesis

Answer 5

straight up originally whilst CO2 limits the amount of photosynthesis
plateaus because temp and light intensity being controlled and CO2 still increasing

Question 6

what does increasing temperature look like on a graph for rate of photosynthesis

Answer 6

like a mountain/hill because photosynthesis increases with temp due to more successful collisions until the chlorophyll active site denatures - no longer complementary

Question 7

what does increasing chlorophyll look like on a graph for rate of photosynthesis

Answer 7

straight positive colleration
