Rate Of Photosynthesis Flashcards
1
Q
What are the three factors that affect how quickly a plant carries out photosynthesis?
A
- light intensity
- temperature
- carbon dioxide concentration
2
Q
What are three reasons why plants grow faster in the summer?
A
- days longer+ more exposure to light
- light intensity is higher
- temperature is higher
3
Q
What is the easiest way to measure the rate of photosynthesis?
A
- to use a plant that lives in water and measure the rate of oxygen production
4
Q
Why do we use sodium hydrogen carbonate solution in the experiment of testing the effect of light intensity on the rate of photosynthesis?
A
The solution provides carbon dioxide that the plant needs for photosynthesis
5
Q
What is the formula for light intensity?
A
1 divided by distance squared
6
Q
What is the unit for “distance squared” in the formula for light intensity?
A
metres
