Lab #2: Energy in Cell Virtual Lab - Week 3 NAME: ________________________________________ 1. What is the importance of the light and dark reactions in photosynthesis? Photosynthesis works by absorbing light. Our sun gives off energy and the chlorophyll from the plant absorb this energy. The energy is then used to separate water into hydrogen and oxygen and then they combine hydrogen and carbon dioxide to make sugars. 2. What happens to food energy during photosynthesis? During

Lab 4: Photosynthesis and Chromatography of Spinach Leaves Discussion: The chromatography of the spinach leaves was taken to establish what pigments were present in the chloroplasts of the leaves. The solvent carried and separated the different pigments up the cellulose paper. The solvent moved up the paper because of capillary action because of adhesion of the solvent molecules and the paper. The pigments dissolved in the solvent also were carried up the paper and were separated because

Photosynthesis and Cellular Respiration Nina R. McCray May 5‚ 2015 Biology Lab (SCIE207-1502-A-07) LaDonna McCowan-Ferrier Photosynthesis and Cellular Respiration Lab Report Introduction This is an investigation of the effect of the intensity of light (photosynthesis) have on the rate of cellular respiration (measured as the number of oxygen bubbles). We will determine whether or not it is possible to examine the relationship between photosynthesis and cellular respiration under controlled

Photosynthesis Lab Kozlowski Kendal Schweiss Hour 6 Introduction: Photosynthesis is carbohydrate production using light and chlorophyll. It is a process when green plants and other organisms turn carbon dioxide and water into carbohydrates and oxygen‚ using light energy trapped by chlorophyll. The rate of photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. 2H2O + CO2 + light -> carbohydrate (CH2O) + O2 + H2O There is a spongy mesophyll

HW Review for Photosynthesis exam: Due Monday March 28 Reminder your lab write up will be a next week. If your lab is this Friday you also will get a week to complete your full lab write-up. Sample questions: 1. twenty-five plants were placed in each of four closed containers and then exposed to light conditions shown in the data table below. All other environmental conditions were held constant for a period of 2 days. At the beginning of the investigation‚ the quantity of CO2 present in each closed

Aquaponics system is a food production system that combines conventional aquaculture‚ raising aquatic animals such as snails‚ fish‚ crayfish or prawns in tanks‚ with hydroponics cultivating plants in water in a symbiotic environment. In normal aquaculture‚ excretions from the animals being raised can accumulate in the water‚ increasing toxicity. In an aquaponic system‚ water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by nitrogen-fixing bacteria

The Rate Of Photosynthesis: Lab report 1) Construct a graph of your data 2) Using the graph‚ estimate the time at which 50 percent of the leaf disks were floating on the surface. The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to

The effect of different wavelengths of light on photosynthesis rate in spinach leaves Abstract: This experiment was performed to test the effect of different wavelengths of light had on photosynthesis. According to the results gathered we can say that if two plants are put under different lights‚ one green and one a normal light‚ that the plant under the normal light will perform photosynthesis at a higher rate than the plant under the green light. This experiment is important because it shows
