Senior Jed Penaso conducts a photosynthesis lab in Marty Stranathan’s Advanced Placement biology class Nov. 30. Students were tasked with testing the effects of temperature, wavelength of light and concentration of a carbon dioxide substrate on the rate of photosynthesis in leaf chads made from punching holes out of spinach leaves. “We were able to measure the rate of photosynthesis within 15 minutes just by following simple procedures,” Penaso said. “Different factors, like the concentration of baking soda and color of light, can have a great effect on the rate of photosynthesis in plants.”
