use 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 “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 carbohydrates

Problem How can you tell pigment separation by using Chromatography? Objective To prepare a chromatogram‚ separate pigments in a leaf and interpret the chromatogram. Hypothesis If I am to put a chromatography paper into a solvent‚ then it would separate the pigments depending on their Rf value. I think the pigments will separate in this order: Chlorophyll A‚ Chlorophyll B‚ Carotene‚ and Xanthophyll. Introduction Chlorophyll is the molecule that absorbs sunlight and uses its energy

Abstract: Two parts of this lab were performed involving photosynthesis and cellular respiration. The first part of the lab consisted of cutting out spinach leaf disks with a straw and then putting them into syringes containing an infiltration solution and sodium bicarbonate. Then the syringes were place under the presence of light and watched as certain disks floated. This part of the lab consisted of watching photosynthesis take place. Then for the second part of the lab we tested cellular respiration

Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of

Benjamin Kleveland 502 October 26‚ 2014 Lab 7 Report Lights Distance and Wavelength Effect on Photosynthesis Photosynthesis and cellular respiration are often mistaken as the same thing. Although they are similar in many ways‚ photosynthesis and cellular respiration are the exact opposite of each other. Not figuratively‚ but literally the reverse (Photosynthesis). They incorporate the others products while adding some outside energy to create a never ending cycle. This brings us to the photochemical

The Effect of Distance from Light Source on the Rate of Photosynthesis Introduction: The effect of distance from the light source on the rate of photosynthesis was tested in this experiment. This was tested to find ways to accelerate the rate of photosynthesis. If plants are placed closer to a source of light‚ then their rate of photosynthesis will be higher because they are receiving more light. Experimental Design: The independent variable is the distance of the beaker from the light source

Title Page Chelsea Maksin Organic Chemistry Laboratory 1 Column and Thin Layer Chromatography: The Separation of Spinach Pigments Russ Hoburg 02/15/2012 Abstract The main goal in doing the column and thin layer chromatography was to separate spinach extract into its components based on polarity and then to analyze the components. The separation of the spinach extract was done using the column chromatography with the wet/slurry packing method. Alumina was inserted into the column to act as

is called photosynthesis. This process is used by plants and other organisms for synthesis of lipids and amino acids or can be metabolized during cellular respiration to produce ATP. This process takes place in chloroplasts‚ which is a plastid that contains chlorophyll and involves two interlinked reactions‚ which are light dependent reactions and light independent reactions. Throughout our lab experiment‚ we focused on the affect access of light has on carbon dioxide during photosynthesis. Carbon

Effects of Light on Photosynthesis Introduction: Photosynthesis is the complex process by which carbon dioxide and water are used to make carbohydrates by using light energy in green plants. The objective of this experiment is to measure the rate of photosynthesis Hypothesis: The petri dish that is exposed to the most light and with the NaHCO3 solution will have the best results and the petri dish that is kept in the dark will have the poorest results. Material and Methods: 1. Get 4 deep petri dishes
