WebHow will you determine the dependence of rate of photosynthesis on color. I will compare the rate of photosynthesis a green light and blue light. Steps. - Step 1: add 3% sodium bicarbonate (NaHCO3) to each tube. - use tweezers to add piece of Elodea to each tube. - add top of volumeter to each tube to assemble. -Cover tube 2 in aluminum foil. WebGreen light drives photosynthesis and controls plant shape. Our previous research (bit.ly/greenblueLEDs) showed that the inclusion of 33% green light did not affect lettuce dry weight under low blue light (0 or 20 µmol·m–2·s–1), although it decreased lettuce dry weight under high blue light (60 or 100 µmol·m–2·s–1).
