Lab Report: Understanding 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. 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†¦show more content†¦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. The materials needed are: a pencil, safety goggles, scissors, chromatography paper strip, capillary tube, spinach plant pigment extract, test tube, cork stopper, graduated cylinder, chromatography solvent (alternative isopropyl alcohol), metric ruler, stopwatch or clock with a secondhand, hook/fashioned paperclip, paper towels, test tube rack, and mortar and pestle. First we obtained a strip of chromatography paper and cut it so it would fit insid e 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. Next we used the pencil to draw 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. 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 darkShow MoreRelatedLab Report On Photosynthesis1364 Words   |  6 PagesPurpose The purpose of this lab is to observe the effect of white, green, and dark light on a photosynthetic plant using a volumeter and followed by the calculation of the net oxygen production using different wavelengths color of white and green light, and also the calculation of oxygen consumption under a dark environment, and finally the calculation of the gross oxygen production.

Solar energy is converted to carbohydrate sugars which are used for metabolism later on. A simple way of explaining this is that the sun s energy is used to make chemical energy. Fig.1 (Royal Society of Chemistry, 2004) Question - Does the intensity of the light source affect the rate of photosynthesis? Hypothesis - If the wattage increases, the average time to float will decrease. Prediction - TheRead MorePhotosynthesis Lab Report1392 Words   |  6 Pagesuse a process called photosynthesis to covert energy from the sun into energy they can use for their activities. The plant’s chloroplasts, along with water, carbon dioxide, and light are the essential elements required for photosynthesis to take place. The â€Å"photo† part of photosynthesis is in reference to the fact that the process requires light. The simplest form of the photosynthesis equation is: H2O + CO2 ----light---- (CH2O)N + O2 As shown in the equation, photosynthesis produces carbohydratesRead MorePhotosynthesis Lab Report866 Words   |  4 Pages Photosynthesis Lab 8 Section 022 Kaileen Savage Tanushree Majumber Introduction â€Å"Photosynthesis is a biochemical process for building carbohydrates using energy from sunlight and carbon dioxide taken from the air†, (Morris, J.

Photosynthesis ultimately produces O2 and glucose. It, like many other biological processes, can be affected by environmental variables. The variable that we altered in the following experiment are intensity, light wavelengths, and pigment types. In order to do this, we conducted three experiments. In the first experiment, we examined the effect of light intensity by placing vials with chloroplastsRead MorePhotosynthesis lab r eport1791 Words   |  8 PagesAbstract Photosynthesis is a food making process for algae and plants. The photosynthesis process rate varies from different wavelengths and intensities of light. This lab will evaluate the optimal wavelengths and degrees of intensity during photosynthesis when chloroplast is exposed to light. The mixtures of DCPIP with water, PO4 buffer, and chloroplast will be prepared in a number of cuvettes. The cuvettes were tested individually at different wavelengths and intensities to find the optimal rateRead MoreLab Report : The Photosynthesis1316 Words   |  6 PagesSummary: The photosynthesis lab is comprised of three short experiments. These experiments showed how to understand and apply the absorbance spectrum and which colors and wavelengths correspond to visible light. In order to fully understand this absorbance spectrum and how to apply it, we initially prepared a substance comprised of acetone, a large spinach leaf and petroleum ether and measured its absorbance in the spectrophotometer. This showed us what wavelengths corresponded to the most absorptionRead MorePhotosynthesis Lab Report1828 Words   |  8 Pagesresults obtained from Col-0 and Cvi-0 ecotypes concur with previous observations by Woodward Lake (2008).

Angel Investing: Frequently Asked Questions What is an Angel Investor? An angel investor is a high net worth individual who invests his or her own money directly into an early stage company, in return for equity (ownership) in the company. In addition to providing financial capital, angel investors mentor and coach their portfolio companies, and help fill in functional or skill gaps in the company. They introduce the companies to other investors, and to colleagues who may be able to increase the company’s value. Most angel investors are entrepreneurs who have exited one or more businesses.

In Search of the Real Bill Gates Essay Example For Students

In Search of the Real Bill Gates Essay Bill Gates, the wealthiest man in North America. Readers Digest did a well brought out biography the most well know man in the business today, but doesnt go into his role in Microsoft itself, but rather in his home life and how he got so smart at what he does. Everything between him as a child dreaming of the perfect computer system (and making his own) to his early stages to making Microsoft, including his family lift, his marriage to his wife and having his first child, Jennifer. His life started out quite the same as every other kids life started out until the age of about when he became less aware of his parents needs as a family. Gates spent most of his time in the basement where he did most of his thinking, fights would often arise due to the fact that Gates would not do anything around the house. Bill had reached grade ten, already fully knowledgeable about the computer industry as it was. Bill Gates was still fighting with his mother until a councilor told them it was useless to reason with him. This continued until Gates graduated from high school and went to university for a degree of business and computer science. The article also goes on to explain when Bill Gates planes to retire his position at Microsoft, which is in ten or so years and to switch back to a family life. His wife was a lot like his mother, he says the person you fight with is the one who is most like you, smart and independent as he describes her. There seems to be a lot of web sites today on the Internet that try to make Bill Gates seem like a bad person. Trying to undermine other companies like Netscape, Sun Microsystems and Apple computer, he says there is a lot of internet hate sites out there that have my name on it, it doesnt affect him in any way or his cutthroat instincts. But like other things, moves by other companies like Netscape or Sun Microsystems keep him awake at night and keep him on his toes.

He has paid or given money for new universities and other learning facilities, by the time he dies; Bill Gates will have donated at least 95% of his funds to organizations around the world and still going. But right now, Bill Gates is more concerned with his daughter Jennifer and planes to run Microsoft as long as he has to, contently making sure that no one is trying to debunk him from his work. After all he is only holding it up for another ten years before he calls it a night.
