BIOLOGY 4: Rate of Photosynthesis

?
How many factors are there that can affect the rate of photosynthesis?
3
1 of 13
What are the three factors that can affect photosynthesis?
Light, carbon dioxide and temperature
2 of 13
What is a limiting factor?
A factor that stops the rate of photosynthesis from increasing
3 of 13
If it's night, what is most likely the limiting factor?
Light
4 of 13
If it's winter, what is most likely the limiting factor?
Temperature
5 of 13
If it's warm and sunny, what is most likely the limiting factor?
Carbon dioxide
6 of 13
How does not having enough light affect the rate of photosynthesis?
It slows it down
7 of 13
What happens to the rate of photosynthesis as the light intensity increases?
The rate of photosynthesis increases steadily, but only up to a certain point
8 of 13
How does not having enough carbon dioxide affect the rate of photosynthesis?
It slows it down
9 of 13
Usually if temperature is the limiting factor, is it too high or too low?
Too low
10 of 13
Why is it that, if temperature is the limiting factor, it is usually too low?
The enzymes needed for photosynthesis work more slowly at a low temperature
11 of 13
What happens to the enzymes needed for photosynthesis if a plant gets too hot?
The enzymes will become denatured
12 of 13
A what temperature do the enzymes needed for photosynthesis become denatured?
45°C
