What did we learn from the GIZMO Lab for the effect of temperature on the rate of photosynthesis? Choose the TWO correct options.

• Temperatures that are right in the middle maximize the rate of photosynthesis.

• Temperature has no effect on the rate of photosynthesis. In other words, photosynthesis occurs at the same rate regardless of the temperature.

• Extremely cold and extremely hot temperatures increase the rate of photosynthesis.

• Temperatures that are very cold and very hot minimize the rate of photosynthesis.
