Use the fоllоwing scenаriо to аnswer the question below: Joe’s biology clаss was studying the effects of different wavelengths of light on the process of photosynthesis in bean plants. Four flats of bean plants (25 plants per flat) were grown for five days. The plants were then exposed to different colors of light as follows: Flat A was placed under red light; Flat B was placed under blue light; Flat C was placed under green light; and Flat D was placed under white light. The plants were exposed to the same temperature conditions and received the same amount of water and carbon dioxide each day. At the end of 20 days, the students recorded the height of the plants in centimeters. What was the independent variable in the experiment?
