Rate Of Phtosynthesis Flashcards
1
Q
What are the three factors that affect the rate of photosynthesis
A
The amount of light, the amount of co2 and temperature
2
Q
Environmental conditions that affect the rate of photosynthesis
A
At night light is the limiting factor, in winter temperature is the limiting factor and if it’s warm enough and light enough co2 is the limiting factor
3
Q
What happens when the light levels are raised
A
The rate of photosynthesis increases steadily
4
Q
What is co2 in photosynthesis
A
A raw material needed for photosynthesis
5
Q
What happens to enzymes at low temperatures
A
They work a lot more slowly
6
Q
What happens if the plant gets to hot
A
The enzymes it needs for photosynthesis and other reactions will be denatured
7
Q
At what temperature do enzymes usually denature
A
At 45•c
