Effect of different light conditions on the rate of photosynthesis
Data Table
Results of Different Light Conditions on Spinach Leaf Disks
| Light Condition | # Disks Floating | % Disks Floating |
| Dark | ||
| Room light | ||
| Sunlamp |
Graph
Prepare a bar graph of the % disks floating for each light condition. Be sure to give the graph a title and label each axis.
Analysis
- Predict what the results will be if your hypothesis is supported.
- What is the independent variable in this experiment
- What is the dependent variable in this experiment.
- Name one other independent variables that could affect the rate of photosynthesis?
- What petri dish is serving as the control group?
- What is the function each of the following components of photosynthesis:
a. Light
b. H2O
c. O2
d. Chloroplasts - In this experiment the spinach leaves were infiltrated with sodium bicarbonate
solution. Why did the disks float again when exposed to light?
