**INFORMATION NEEDED TO COMPLETE THE FOLLOWING PROBLEMS**
Independent Variable: This is the cause.
Dependent Variable: This is the response or effect.
One hundred samples of several different plants were placed in each of six sealed containers with water in them. At the end of two days the amount of oxygen produced was measured. Results are shown in the table below.
Container Plant Height of Plant Light Intensity Source of Light Distance from Light mL O2 Produced
1 Iris 4? High Artificial 6? 16
2 Iris 4? High Natural 6? 13
3 Iris 6? Low Artificial 5? 12
4 Carnation 6? High Natural 4? 13
5 Carnation 6? Low Natural 4? 9
6 Carnation 4? Low Artificial 5? 14
13. Based on the data presented in the table, which two containers could be correctly used to compare the rate of photosynthesis at two different light intensities? (5 points)
a. 1 and 2
b. 2 and 3
c. 1 and 5
d. 5 and 6
e. 4 and 5
14. Compare Containers 1 and 2. What independent variable is tested by this comparison? (5 points)
a. Kind of plant
b. Height of plant
c. Light intensity
d. Distance from light source
e. Light source
15. Which container had the slowest rate of photosynthesis? (5 points)
a. 1
b. 2
c. 3
d. 4
e. 5
f. 6
16. (Application) How might the information gained from this lab pertaining to photosynthesis and pigments be useful to the student or how can the student apply this knowledge to everyday life as a non-scientist?
