Lab Report: Photosynthesis Name: Purpose of this Lab What is the goal of this lab? What question are you trying to answer‚ or what problem are you trying to explain? In this lab I will perform experiments to explain photosynthesis. I will answer questions like what does photosynthesis do and how does photosynthesis work? Hypothesis After reading the lab instructions (but before starting the lab) record your best educated guess about what will happen in the experiment. Explain

AP Lab #5 Plant Pigments/Photosynthesis I. Identifying the Effects of Different Variables of Light and Carbon Dioxide on the Rate of Photosynthesis and Observing the Separation of Pigments Through Chromatography II. Introduction Plants have a variety of pigments‚ all of which absorb a different color of light. The three main pigments are chlorophyll a‚ chlorophyll b and carotenoids. Chlorophyll a is the primary plant pigment that absorbs red and blue light‚ which ultimately appears green to the human eye

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 us the

Photosynthesis Abstract: An experiment was carried out to determine how certain factors such as light intensity and availability of carbon dioxide‚ affected the rate of photosynthesis. The rate of photosynthesis was measure by the amount of oxygen produce (cm3/min). A valid conclusion was made and most of the results were in accordance with the prediction‚ although there were some anomalies present. The errors and limitations were evaluated and some improvements were suggested. Introduction: Photosynthesis

Evidence of Photosynthesis Photosynthesis is the process during which a plant’s chlorophyll traps light energy and sugars (glucose) are produced. In plants‚ photosynthesis occurs only in cells with chloroplasts. Water (H2O)‚ carbon dioxide (CO2) and light energy are required. The light energy is absorbed by the green pigment‚ chlorophyll‚ and is converted into chemical energy‚ which causes the water drawn from the soil to split into molecules of hydrogen and oxygen. The hydrogen combines with

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

germination of a seed affected by sunlight?” Experimental Hypothesis: We believe these results will occur. 1. The seeds that are water deprived (1 mL of H2O a day) will not grow very well due to a lack of water which is important in photosynthesis and also lacks nutrients. The seeds may also die off due to a lack of water. 2. The seeds that are have a proper amount of water (10 mL of H2O a day) will grow the best and achieve the greatest height‚ and overall best appearance.

process of photosynthesis requires sunlight for its nutrients to make their way into the chlorophyll on green plants. This suggests that without direct sunlight‚ photosynthesis will not be completed correctly or the plants functions will not work properly. Majority of plants that undergo photosynthesis have chlorophyll stored within them‚ it is what gives them their green color. However‚ there are few species of plants that don’t acquire chlorophyll‚ but still undergo the process of photosynthesis. Specific
