Question

The concentration of carbon dioxide in parts per million (ppm) was measured for a closed container in several situations. Which of the following data collected would demonstrate the action of photosynthesis?

Answer 1

The data collected would demonstrate the action of photosynthesis as when the container included a plant exposed to light, carbon dioxide concentration went from 800 to 600 PPM

Explanation:

• The data collected would demonstrate the action of photosynthesis as when the container included a plant exposed to light, carbon dioxide concentration went from 800 to 600 PPM.

• In a closed system, a decrease in carbon dioxide is evidence of photosynthesis, while an increase in carbon dioxide is evidence of cellular respiration. A plant in the dark will only carry out respiration, but in the light, the plant can carry out both respiration and photosynthesis.
