Q

How does the rate of photosynthesis change as light energy is increased?

A

1) It increases steadily up until a certain point.

2) After this point is reached, it won’t make a difference because light intensity is no longer the limiting factor.

Q

How does the rate of photosynthesis change as temperature is increased?

A

1) It causes it to increase because it affects the enzymes involved.
2) Up until a certain point.
3) If the temperature gets too high, the enzymes will denature.
4) So the rate of photosynthesis decreases.
