This next week or so in my Cell Physiology class, we are studying metabolism in plants. My group and I set out to see if we could increase the efficiency or rate that photosynthesis occurs in our plant.
We set up a control, giving it 200 mL water everyday and along side it we set up a plant that was given the same amount water everyday, but every third day we would give it 200 mL coffee instead. To study it further, we set up a third plant that was given 200 mL coffee everyday. We felt that this would help us see how much of a role coffee was having on our plants’ ability capture energy via photosynthesis.
So how do we do that? Well, it’s pretty involved and it’s an ongoing experiment, but we are essentially extracting the chlorophyll from the leaves our plant and then comparing the pigment levels between the plants tested. The pigment levels will tell us if one should give coffee to their plant!
