Serjik [45]

A student set up an experiment to show the effect of light color on photosynthesis in Elodea plants. She filled two test tubes with distilled water and placed a piece of Elodea in each of the tubes. She added a drop of phenol red, which turns red in a basic solution and yellow in an acidic solution. She blew in each tube before placing the volumeters on the top of the tube to add carbon di oxide.

She blew in the test tubes to add the carbon di oxide to the tube which caused the distilled water to become more acidic so the phenol red turned yellow, and when she exposes the tubes to different set of color lights. So, in the presence of light it turn the water into red color, which shows the process of photosynthesis depending on the wavelength of different color.
