How does temperature play a role in rate of photosynthesis?

Which of these conditions would decrease the rate of photosynthesis in a plant?

• Above average precipitation
• Changing the daylight hours from 14 hrs to 10 hrs
• Changing the CO₂ concentration from 380 ppm to 410 ppm
• All of these choices

As light intensity (amount/lumens) decreases in a forest, what will happen to the rate of PHOTOSYNTHESIS?

• Slow down with less light

• Continue at the same pace

• Speed up with the decreasing light

• Stop completely

The graph is showing you that plants will have an ​ (a)   temperature where the ​ (b)   of photosynthesis will be highest. Too ​ (c)   or too low of temperatures will ​ (d)   down the rate/stop the reaction.

• optimal
• rate
• high
• slow
• low
• worst
• least

In general, plants have a maximum (a)   of the photosynthesis reaction. There is always a peak regardless of if you keep adding CO2, water, or light.
