In the photosynthesis lab, a group of students found that in the blue light condition, there was a change in absorbance (ΔA620) of 0.324 in extracted spinach chloroplasts. The students later went on a hike and located a plant they had never seen before and were interested in how the photosynthesis rates would compare to their experiment with spinach chloroplasts. They extracted chloroplasts of the unknown green-leaved plant and exposed them to the same experimental conditions as before. The students calculated the ΔA620  to be 0.100.  Which plant (spinach or unknown) has the highest rate of photosynthesis? Explain your answer using evidence, being sure to demonstrate your understanding of the dependent variable.

Photosynthesis

Plants have a capacity that we humans can only imagine— the ability to produce food from sunlight. Sure, we can prepare some dishes that we can savor on, but it become possible because of the plants (as they serve as a producers of all the raw materials required). Photosynthesis is the method of assembling carbohydrates with the aid of sunlight.
