Will mark worth 30 ! which temperature listed below allows for the greatest rate of photosynthesis? use the graph below to determine the answer.
a. 10 degrees celsius
b. 15 degrees celsius
c. 20 degrees celsius
d. 25 degrees celsius

25 degrees Celsius, as this is the highest point on the graph which means that the oxygen flow is optimal at this temp. Since oxygen is a product of photosynthesis, if more is flowing at 25 degree, more photosynthesis is happening.
