Interpreting / Limiting Factor Graphs

Question 1

what is meant by inverse proportion

Answer 1

when one one value increases , the other decreases

Question 2

what is meant by direct proportion

Answer 2

as one value increases so does the other

Question 3

is the rate of photosynthesis inversely or directly proportional to the distance of lamp from the plant

Answer 3

inversely proportional

Question 4

what is the inverse square law

Answer 4

light intensity is directly proportional to : 1
——————
distance^2

Question 5

describe the inverse square law

Answer 5

every time you double the lamps distance, the light intensity quarters

Question 6

describe the limiting factor graph for temperature (x) against rate of photosynthesis (y)

Answer 6

as the temperature increases, the rate of photosynthesis increases until it reaches an optimum temperature and then it decreases as the temperature continues to increase

Question 7

explain the limiting factor graph for temperature (x) against the rate of photosynthesis (y)

Answer 7

temperature increases kinetic energy in particles which causes an increase in collisions of particles which increases the rate of photosynthesis
optimum temperature has the most collisions however too much heat means the enzymes denatures

Question 8

what happens when the enzyme denatures

Answer 8

the substrate no longer fits into the enzymes active site

Question 9

describe the limiting factor graph for light intensity (x) against rate of photosynthesis (y)

Answer 9

as the light intensity increases, as does the rate of photosynthesis until it reaches a point then plateaus (levels out)

Question 10

explain the limiting factor graph of light intensity (c) against the rate of photosynthesis (y)

Answer 10

the rate of photosynthesis increases as the light intensity increases because light is required for photosynthesis to occur
it plateaus because of other limiting factors such as CO2 concentration

Question 11

describe the limiting factor graph of CO2 concentration(x) against the rate of photosynthesis (y)

Answer 11

as the CO2 conc increases, as does the rate of photosynthesis until a certain point then it plateaus

Question 12

explain the limiting factor graph of CO2 concentration (x) against the rate of photosynthesis (y)

Answer 12

the rate of photosynthesis increases as the CO2 conc does because CO2 is a factor rehired for photosynthesis to occur
it plt said because of a different limiting factor such as light intensity
