Biology Final Exam Review

The process of photosynthesis is plants producing oxygen. Two students were investigating the effect of light intensity on the rate of photosynthesis of elodea, an aquatic plant.  They exposed elodea to different amounts of light. After exposing the elodea to different amounts of light, the students counted the number of bubbles of oxygen produced in the water to determine the rate of photosynthesis.
What QUANTITATIVE DATA would be gathered?

• Light intensity
• Rate of photosynthesis
• Aquatic plant (elodea)
• Number of bubbles of oxygen

After exposing the elodea to different amounts of light, the students counted the number of bubbles of oxygen produced in the water to determine the rate of photosynthesis.
Which is a CORRECT HYPOTHESIS for this experiment?

• If light intensity increases, then the photosynthetic rate will increase.
• Light intensity will increase the rate of photosynthesis.
• If the rate of photosynthesis increases, then the light intensity will increase.
• If the rate of photosynthesis increases, then the number of bubbles will increase.
