Question

A scientific explanation states that plants produce carbohydrates through the process of photosynthesis and that photosynthesis can only take place in the presence of light and carbon dioxide. A student does an experiment to see whether light intensity affects the rate of photosynthesis. The data collected during the experiment is summarized in the graph below. Does the student's data support the scientific explanation above? A. Yes, the graph shows that the rate of photosynthesis continuously increases with light intensity. B. No, the graph shows that as light intensity increases, photosynthesis tapers off. C. Yes, the graph shows that the rate of photosynthesis increases with light intensity up to a point. D. No, the graph shows that there is no direct relationship between the rate of photosynthesis and light intensity.

Answer 1

Answer:

C. Yes, the graph shows that the rate of photosynthesis increases with light intensity up to a point.

Answer 2

The dependent variable is the part of the experiment that depends on the other part, the independent part. The dependent variable would be the plant because it's growth depends on the light wavelength.
