Identify the data set that is most likely from the flask wrapped completely in foil, and explain the evidence you used to determine your answer. support your explanation using information about the processes that are occurring in the flask during the experiment.

Note: I have chosen to answer both a and b in the second image as they are the opposite case to each other.

General information: Photosynthesis is the process through which plants produce nutrients necessary for survival and growth by utilizing sunlight as an energy source and carbon dioxide together with water. Oxygen is released as a by-product.

Answer:

a. The plant exposed to 100% light intensity will have the maximum amount of photosynthesis. Thus, this plant will have the highest amount of oxygen production. The plant that exhibits this, is found in flask 2, where after 12 hours in light it has the highest production (8.4).

b. The plant covered in foil will be the opposite of point a. As no photosynthesis can occur due to a lack of sunlight, it will show a constant decrease in . This occurs due to the fact that plants, as well as animals, have cellular respiration. During this process oxygen is used to produce cellular energy. The plant that exhibits this is in flask 1 where after 12 hours in light shows a decrease from 4.1 to 3.2.

All plants will show a decrease in O2 in the 12 hours of dark due to a lack of photosynthesis and the presence of cellular respiration.

the answer is:

carbon dioxide
