The Aquatic Plant Elodea Is Commonly Used to Study Photosynthesis

The aquatic plant Elodea is commonly used to study photosynthesis. You put some Elodea in a test tube, shine light on the plant, and count the bubbles that were released under varying conditions. Which results would you expect to see in your analysis of photosynthetic rate?

A) the number of bubbles increase indefinitely with increased illumination
B) as light intensity increases, the number of bubbles increase and then rapidly decrease
C) at high light intensities, the number of bubbles increase when the temperature is increased to human body temperature (37 degrees C)
D) at low light intensities, the number of bubbles increase as temperature increases and the number of bubbles decrease as carbon dioxide concentration decreases
E) at high light intensities, the number of bubbles increase as carbon dioxide concentration increases
