Three Anacharis plants were placed inside inverted test tubes filled with water. One test tube was exposed to low light, another to medium light while 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? Record your answer below

Answer value

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:

carbon dioxide concentration

water availability

ambient temperature

light intensity;

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex
