    Abstract: The rate of photosynthesis and cellular respiration can change in varying conditions. How does the rate change with varying degrees of temperature and light exposure? To test this algae beads were exposed to a CO2 indicator‚ which changes colors based on the level CO2 level present. The algae beads were exposed to two different variables‚ light and temperature and tested for color change‚ Ph‚ level‚ and CO2 absorbance level. The beads were exposed to a light and a dark condition‚ and another

    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

    for waste is carbon dioxide (CO2) and water (H2O). CO2 can combine with water to form carbonic acid during cellular respiration. Phenolphthalein can be used to help detect any changes in pH because of production of CO2 during cellular respiration. Phenolphthalein usually appears clear or colorless in acidic solutions‚ and red in basic solutions. Procedures: In the first lab‚ seven test tubes were attained and six of them were filled with the solutions that were listed (Na Pyruvate‚ MgSO4

    rate of photosynthesis until optimal levels are reached‚ then plateauing of results will occur. The hypothesis was refuted by evidence shown in the results (table two) as 0.5% concentration produced the greatest rate of photosynthesis‚ 3.10x10-3. Concentrations of 5% and 10% were deemed unusable as the agapanthus discs would not submerge‚ therefore the results did not enable a range of data. The results of the data indicate that 0.5% NaHCO3 is optimal in determining the rate of photosynthesis‚ 3.10x10-3

    Maria Ruiz Feb.7‚ 2012 Bio. Report Problem: Dows light intensity and wavelength affect Photosynthesis? Introduction: Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. It produces sugar and other organic compounds such as lipids and proteins. The sugars are then used to provide

    layer of flat cells and supported by a mesh of fine elastic fibers. The alveoli are surrounded by a rich network of pulmonary capillaries (Couch and Berger‚ 2004). Our lungs are a network of connected tubes that bring oxygen from the air into our blood‚ nourishing the trillions of cells that make up our bodies. The lungs also clean the blood of carbon dioxide waste created when cells use oxygen (Natural Geographic‚ 2012). In experiment one I hypothesize that the effect of respiration changes on carbon

    highest amount rise‚ which will show us the optimal color of light for photosynthesis. These different colors of light included blue‚ red‚ green‚ fluorescent‚ regular light‚ and classroom light. The classroom light was our control cup during the lab. Before we conducted our experiment‚ the class learned about the photosynthetic process of‚ not only spinach discs‚ but plants in general. As I did more research on photosynthesis‚ the Calvin Cycle‚ wavelengths and pigments required for a proper equation

    1112.317 Lab Report Amounts of Carbon Dioxide/ Oxygen Animals are Producing/ Consuming Introduction Every cell needs a source of energy in order to perform their daily functions. However the process to get this energy is different for plant and animal cells. Plants cells undergo a process called photosynthesis where light energy from the sun is used to convert carbon dioxide and water into glucose and oxygen. For animal cells‚ the process is known as cellular respiration by which cells break down
