Photosynthesis is the process plants use to capture and store the Sun’s energy in chemical form. In aquatic plants like Elodea, light, carbon dioxide, and water are absorbed to produce glucose (a type of sugar) and oxygen. The oxygen escapes as bubbles from the plant’s surface - which can be counted to estimate the rate of photosynthesis.
The chemical reaction for photosynthesis can be written as:
When Elodea is placed near a bright light source, photosynthesis occurs faster, and the rate of oxygen bubble production increases. If the light source is dimmed or the plant is moved farther away, fewer bubbles form because the plant receives less light energy to power the process.

Which observation best supports that an aquatic plant is performing photosynthesis?
Using the table and Figure 1, describe the relationship between light intensity and the number of oxygen bubbles produced.
Does the data support the idea that photosynthesis depends on light?
Claim:
Evidence:
Reasoning:
Explain why oxygen production slows down when aquatic plants are placed in low carbon dioxide conditions.
Compare bubble production in warm water versus cold water. What does this suggest about enzyme activity in photosynthesis?
Which statement best explains why a plant gives off oxygen during photosynthesis?
