photosynthesis experiment

Question 1

how can the rate of photosynthesis be measured

Answer 1

by recording the amount of oxygen produced or carbon dioxide used

Question 2

why cant theses measurement be relied upon

Answer 2

as they are also affected by respiration which plants do all the time so respiration rate must be treated seperatelu

Question 3

what is the compensation point

Answer 3

when the rate of photosynthesis are equal so there is no net change in the oxygen or carbon dioxide concentration

Question 4

how does temperature affect photosynthesis

Answer 4

influences the enzyme which are required for photosynthesis an increase in temperature increases the kinetic energy and speed of the molecules so are collide more often

Question 5

what happens when there is higher levels of co2

Answer 5

the faster the rate of the calvin cycle as co2 is the substrate for the enzyme rubisco so is used in the calvin cycle to combine with rubp

Question 6

why and how does light influence photosynthesis

Answer 6

it is the source of energy in the light dependent stage for the production of atp and nadh so higher the insentity the rater rate of photosynthesis
