Measuring The Rate Of Photosynthesis Flashcards
1
Q
How do you measure the rate of photosynthesis
A
-using a photosynthometer
2
Q
What is rate
A
-quantity taken up per unit time
3
Q
What do we measure to be able to work out the rate of photosynthesis
A
-measure the volume of oxygen produced per minute
4
Q
What type of plants do we use to measure the rate of photosynthesis
A
-aquatic plants
5
Q
What are the 2 limitations of finding the rate of photosynthesis by measuring the volume of oxygen produced per minute
A
1) some of the oxygen produced by the plant will be used for respiration and not photosynthesis
2) there may be come dissolved nitrogen in the gas collected
6
Q
How do you calculate the volume of gas collected
A
-length of bubble/distance bubble travelled x pi r^2
