AP Biology Photosynthesis Lab Bethany Boyer Due 11/12/14 Lab Write-Up Questions First Experiment 1) The independent variable in this experiment was the presence of CO2 (carbon dioxide). The dependent variable was the speed at which the leaf disks started to float. 2) In the leaf tissue‚ the bicarbonate and light are combining to carry out photosynthesis. This will cause oxygen to collect in the leaf tissue‚ causing it to rise. 3) If we were to boil the leaf disks‚ the reaction would most likely

6/7 Photosynthesis and Cellular Respiration Review 1. _Energy__ is required for transport of certain materials‚ movement‚ growth‚ and reproduction. 2. Define autotroph and heterotroph. Name the organisms that make up each. Autotrophs use the suns energy to produce their food. Heterotrophs consume other organisms to obtain food. Plants Animals 3. ___Sun__ is the ultimate source of energy for all living things on Earth based on the cycle of photosynthesis and cellular respiration. 4. What

- Cellular Respiration Assignment - 1. What two molecules are formed when a phosphate is removed from ATP? There are three phosphate groups in ATP molecule (Adenosine Triphosphate)‚ when removing one phosphate molecule‚ ADP molecule is formed (Adenosine Diphosphate). 2. What is the function of ATP? Describe the molecule. The function of ATP is storing energy within a cell. ATP is adenosine triphosphate‚ C10H16N5O13P3‚ a high energy complex‚ giving the necessary power to push metabolistic

Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things

Cell Respiration & Photosynthesis BIO STUDY GUIDE (Ch. 9.1-9.5‚ 10.1-10.3) I) CELLULAR RESPIRATION A) Catabolic Pathways A.1) Fermentation: partial degradation of sugar that occurs w/o oxygen A.2) Cellular Respiration: oxygen is used A.3) Redox Reactions (Oxidation-Reduction that exchanges electrons) Oxidation: loss of electrons (energy must be added) Reduction: addition of electrons. (-) charged electrons added to atom reduce amount of (+) charge of that atom A.4) Stepwise Energy Harvest

Submit your completed lab report to the Lab: Photosynthesis Lab assignment link for grading. For information on how this assignment will be graded‚ please visit the Course Information sectionChlorophyll and Accessory Pigments A pigment is any substance that absorbs light. The color we see comes from the wavelengths of light that reflect. Chlorophyll‚ the green pigment common to all photosynthetic cells‚ absorbs all wavelengths of visible light except green. The green reflects back to our eyes

Bio Block B Photosynthesis Lab 12/6/12 Introduction: Photosynthesis is affected by light intensity‚ water‚ and temperature. Plants grow more abundantly because the weather is warm. Carbon Dioxide given off by animals is consumed by plants that replace the oxygen animals take it. Experimentation will help understanding how plants are vital because of the oxygen they release. If leaf disks in the experiment release oxygen‚ they will undergo photosynthesis and float. If there

Photosynthesis and the Amount of Light _______________________________________________________________________ I. Introduction Photosynthesis the process where plants use sunlight (energy) to synthesize foods forming the products carbohydrates and water (H20 + CO2 + Light CH2O + O2). For photosynthesis to take place they need water‚ carbon dioxide and light and chloroplasts. Light is absorbed inside he thylakoid

Analysis: In this lab we measured the rate of respiration of germinating mung beans and germinating peas at room temperature and 10 degrees Celsius. The rates of respiration at room temperature were higher than the rates of respiration in cold water. The reaction rate of the germinating peas at room temperature was .0125 ml/min and the reaction rate of the peas at 10 degrees Celsius was .0095 ml/min. The same is true for the germinating mung beans. At room temperature the rate of reaction was .0105
