Rate of photosynthesis Flashcards
1
Q
What can the pondweed be used to measure ?
A
effect of light intensity in photosynthesis
2
Q
What does the rate pondweed produces oxygen correspond to?
A
the amount of photosynthesis- faster oxygen produced faster photosynthesis
3
Q
First step of practical ?
A
source of white light is placed a distance from the pondweed
4
Q
second step of this practical?
A
pondweed is left to photosynthesise for a certain time, oxygen produced will be collected out of the capillary tube
5
Q
Third step of practical?
A
at end of experiment syringe is used to draw gas bubble in the tube in the tube up alongside the ruler and the length of the gas bubble is measured
6
Q
How many times is this experiment repeated?
A
Twice with different distances from the light source
