By Cheryl G Introduction & Background Photosynthesis is the process by which light energy is converted to chemical energy. It occurs within each chloroplast in most of the green plants, and Carbon dioxide is one of the main components of this process The process ofcreating energy from light is known as photosynthesis. It’s an extensive process that undergoesmultiple steps that produces the oxygen we use to breathe. When light is absorbed into the leaf ofa plant, electrons within each photosystem are boosted to a higher energy level (Urry et al)/5(47)

Lab Report: Understanding Photosynthesis Gen Biology Lab Abstract: This lab was called lab report on 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, lab report on photosynthesis, and varying pigmentation.
Introduction: 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 photosynthesis. Sir Isaac Newton was an English physicist lab report on photosynthesis used a light prism and demonstrated how white light contains varying colors.
These colors range from red at one end of the visible spectrum to the color violet at the other end. Then another spectrum was added called the electromagnetic spectrum or a continuous spectrum by James Clerk Maxwell; this included: cosmic rays, visible light, x-rays, and radio waves. For plants to use sunlight, they have to absorb it, lab report on photosynthesis. So pigments absorb light energy, lab report on photosynthesis. Chlorophyll is a pigment in leaves that reflect green light waves.
This is the most important pigment in photosynthesis and there are also accessory pigments used in plants. Also in this lab there is the internal and external anatomy of a typical leaf. Materials and methods: The first procedure dealt with the internal anatomy of a leaf. The materials needed are: colored pencils, a prepared slide of a leaf, and a compound microscope.
After obtaining the prepared slide of a leaf, we used a compound microscope to observe the leaf. Then we sketched the leaf and labeled the following structures: cuticle, epidermis, mesophyll, palisade parenchyma, spongy parenchyma, stomata, and guard cells. The next procedure dealt with the external leaf structure.
The materials needed are: a dicot leaf, dissecting microscope or hand lens, and colored pencils. First we obtained a leaf from our instructor. Then we sketched the leaf and labeled the blade and petiole. The following procedure dealt with a chromatogram. First we obtained a strip of chromatography paper and cut it so it would fit inside a test tube with it barely touching the bottom of the tube.
Also, when touching the strip, touch the sides only. Then we attached firmly the top of the strip to a hook or fashioned paperclip at bottom of the cork stopper. Make sure it fits in the test tube, lab report on photosynthesis.
Next we used the pencil to lab report on photosynthesis a faint line across the strip two centimeters from the bottom tip of the strip. We placed the cork and strip in place, and we put a mark on the test tube one centimeter below the top of the stopper.
The next step was to place the strip of chromatography paper on a paper towel. Then dip a capillary tube into the plant pigment extract spinach pigment extract provided by the teacher.
The tube will fill on its own, lab report on photosynthesis. We applied the extract to the pencil line on the paper, blew the strip dry, and repeated it three to four times until the line on the paper is a dark green.
We used a graduated cylinder and carefully measures 5 milliliters of chromatography solvent to pour into lab report on photosynthesis test tube. Then we placed the chromatography strip in the test tube, positioning it so the tip of the strip barely lab report on photosynthesis 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 lab report on photosynthesis paper to let it dry. Then we identified the pigment bands, the migration, and the rate of migration, lab report on photosynthesis. 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, lab report on photosynthesis.
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, lab report on photosynthesis. 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, lab report on photosynthesis.
We inserted the straw into a test tube, and blew gently to release carbon dioxide into the tube. The water will become orange-yellow in color more acidic and carbonic acid is formed. Then immediately place the stopper on the test tube. Results: Paper Chromatogram: Table The fig was described as green, huge, and almost perfectly shaped. Then the dogwood leaf was crunchy and a little brittle. Then the Jane magnolia was slightly brittle, yet soft at the same time.
When doing the color smears the results were that the fig was bright green, the dogwood was rusty brown-orange, and the Jane magnolia was dark yellow with hints of brown. The carbon dioxide uptake color changed from a pink to a light yellow. The chromatography experiment was designed to see the different pigments in plants and which determines how much sunlight is let in. This affects how successful photosynthesis was at the time.
Then the carbon dioxide experiment was to see how easily plants are effected by the amount of carbon dioxide in n their surroundings. Conclusion: Photosynthesis is a very complicated process for students to understand.
The uptake of carbon dioxide depending on the amount affects the rate of photosynthesis. Also another huge factor in the process of photosynthesis is sunlight. It helps determines on what pigments the plant possess and how much work they can do. This essay was written by a fellow student.
