  • Cell Homogenate Experiment

    1417 Words  | 6 Pages

    Experiment I (Parts 1 & 2) I. Question and Hypothesis In parts 1 and 2 of experiment I, the main goal was to prepare a cell homogenate from broccoli florets and determine which cell fraction had the most electron transport chain activity. Electron transport activity could be determined by the cell fraction with the largest number of chloroplast, which was indicated by the artificial electron acceptor called DCIP. This artificial acceptor can be read using a Spectronic 20 to measure the absorbance

  • Solar Cell Experiment

    2091 Words  | 9 Pages

    Solar Cell Experiment Introduction: Solar Cells convert light energy to electrical energy, so are transducers. Aim 1: To investigate any relationship present between the distance between a solar cell and a lamp, and the current output of the solar cell, at a fixed voltage. Aim 2: To investigate any relationship present between the power supplied to a bulb, and the current of a solar panel, at a fixed distance apart. When investigating a solar cell, there are several variables

  • Solar Cell Experiment

    2285 Words  | 10 Pages

    Solar Cell Experiment Aim: To see how individual factors affect the output of a solar cell. Factors affecting the output of a solar cell: This experiment is going to be performed in the confines of a school laboratory, and so the complexity and cost of the experiment(s) should reflect this. However, to see how different factors affect the solar cell output, I will need to perform at least two experiments. The question is, which ones? · Distance from the light source will affect the

  • Half Cells for Voltage: An experiment

    764 Words  | 4 Pages

    ELECTROCHEMICAL CELLS Purpose: In this experiment, several different half-cells will be prepared and connected to find the voltages generated. Also, the concentration will be change in one of the solutions to see how this affects the cell potential. Thirdly, the electrical potential of a cell containing silver and silver chloride will be measured. Lastly, a cell containing copper (II) and ammonia will be constructed. The potential and the Nernst equation will be used to calculate the formation

  • Experiment on the Functions of Passive Transport in Red Blood Cells

    1772 Words  | 8 Pages

    other words, the plasma membrane is semi-permeable that it allows nutrients to enter the cell but keeps out undesirable substances. This property allows the cell to segregate its inner cytoplasm from the external environment. There are two different ways to pass though this membrane: active and passive transport. Active and passive transport are both biological process that move oxygen, water and nutrients into cells and remove waste products; however, these two processes happen in a different mechanism

  • An Experiment to Find Out the Effect of Osmosis on Potato Cells

    839 Words  | 4 Pages

    An Experiment to Find Out the Effect of Osmosis on Potato Cells Plan ==== Apparatus: · A borer · 25 test tubes · 5 test tube racks · 2 potatoes · A ruler · A sharp knife Variables: Four different sugar solutions at 10%,20%,30%and40% and distilled water Hypothesis: I hypothesis that the higher the sugar the less the potato size will increase. I think this because I think it will be harder for the liquid to get in because it is denser. Using the borer make cuts

  • Investigating the Concentration of Sucrose in Cells of Carrots and Potatoes

    2785 Words  | 12 Pages

    Concentration of Sucrose in Cells of Carrots and Potatoes Plan Introduction Osmosis is defined as 'the net movement of water molecules from a region of high water concentration to a region of lower water concentration through a partially permeable membrane'. In my experiment the process of osmosis will be due to the concentration of sucrose inside the cell compared to outside. Therefore if there is a higher concentration of sucrose molecules outside the cell then the net movement of

  • The Effects of Glucose Concentration on Osmosis in Potato Cells

    2059 Words  | 9 Pages

    The Effects of Glucose Concentration on Osmosis in Potato Cells Apparatus: - * Potato * Blade * Cork borer * Stopwatch * Glucose solution * 50cm3 Measuring cylinder * Electronic Balance (scale in grams) * Five 200cm3 beakers * Forceps * Labels * Water bath Procedure: - * First cut the potato into half * Using the cork borer cut the potato to obtain five cylinders of potatoes (Make sure that the potato cylinders are from the same potato as the

  • Investigating Osmosis in Potatoes at Different Concentrations of Sucrose Solutions

    2740 Words  | 11 Pages

    The aim of this experiment is to find out how solutions of different strength affect the osmotic movement. Preliminary work: For the preliminary work, I did a try out test to see if the method I had works. Also, I wanted to use the results I have after completing the experiment so that I can have an overview of how sucrose solutions of different strengths affect the diffusion of water in potato chips. I would also use what I have concluded at the end of the experiment to make a final

  • The Pros And Cons Of The Scientific Method

    744 Words  | 3 Pages

    world with experiments. Scientists created the scientific method to make a “conclusion about the world around them” (1). “The Scientific Method helps to “organize thoughts and procedures to finalized conclusions” (2). The Scientific Method consists of six steps to carry out an experiment reach. The first step is, ask a question. When an individual questions the things around them they tend to do an experiment to see if it can be affected by something. Before you can perform the experiment the second
