Three Anacharis plants were placed inside inverted test tubes filled with water. One test tube
was exposed to low light, another to medium light, and another was exposed to high light. The
table provided shows the results of this experiment. Notice that more oxygen was produced by
the Anacharis in high light.

Based on the information provided, what is the difference in volume (in mL) of oxygen
produced between the low-light and high-light plants after 45 minutes?

Anacharis in High Light produces more mLof oxygen per min than Anacharis in Low Light Anacharis and in Medium  Light.

Explanation:

The increased  light intensity also increases the rate of photosynthetic activity. As photosynthesis occurs, the energy from sunlight, along with CO2 is converted to chemical energy in the form of glucose.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

or Carbon dioxide + water = energy (glucose) + oxygen

Photosynthesizing cells in green plants produce oxygen as a waste product. As this process is rate-limited, certain factors may increase the reaction rate. These include:

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
