Lab Report on Photosynthesis
Gen Biology Lab
Abstract: This lab was called photosynthesis: understanding photosynthesis. It is a highly complex process that needs to be broken down in many steps to understand how it works. This lab covers the big components in photosynthesis including carbon dioxide intake, light consumption, and varying pigmentation.
Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special way of using the ATP they produce. Photosynthesis is a process where plants harness the sunlight they receive and they produce carbohydrates, as well as oxygen for living things and other plants. Now the sunlight ultimately powers the process of …show more content…
Then we placed the chromatography strip in the test tube, positioning it so the tip of the strip barely touched the solvent. Then we kept the test tube capped and put it in the test tube rack. We then observed as the solvent rose on the paper and we recorded our findings. After the solvent has moved up to the line drawn on the paper, remove test tube and the paper from the test tube. We set aside the paper to let it dry. Then we identified the pigment bands, the migration, and the rate of migration. The proceeding activity dealt with leaf collection and pigments from native trees. The materials needed are: at least three leaf specimens collected from a nearby source and a piece of typing paper. First someone in our group took a walk around campus and collected three different leaves. We then had to identify the plant specimens and smear them onto a piece of white typing paper. But right before smearing them, we observed them and described what we saw. We then recorded what we saw on the smeared paper. The least procedure dealt with the intake of carbon dioxide. The materials needed are: a test tube, a large leafy piece of Elodea, test tube rack, medicine dropper, 1% solution of phenol red (pH indicator), stopper, straw, and water. First fill two thirds of a test tube with water and place the Elodea in a tube. We added four to five drops of the phenol red to the test tube. We inserted the straw into a test tube, and blew gently to release carbon
