Question/Purpose: The Question or Purpose of our lab is to answer the question “How is the 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

Background: Photosynthesis is the reaction carried out by green plants to produce a supply of food. The reactions occur in the chloroplasts and require light energy. 6CO2 + 6H2O C6H12O6 + 6O2 In aquatic plants‚ the production of oxygen can be used to measure the rate of photosynthesis as the oxygen bubbles can

growth. For those interested in harvesting duckweed‚ future studies can focus in determining the amount of light needed for optimal growth. Introduction Plants are able to convert light energy into chemical energy through the process of photosynthesis (Campbell & Reese‚ 2005). This process is dependent on both abiotic and biotic factors. Since plants are autotrophs‚ the most vital are abiotic factors such as light‚ temperature‚ wind‚ water‚ and atmospheric gases (Campbell & Reese‚ 2005). The

increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate of photosynthesis will also increase in a linear trend. Carbon dioxide concentration is shown to be directly proportional to rate of photosynthesis ([CO2] ∝ rate of photosynthesis). The line of best fit

of CO2. These values of the photosynthesis (plus respiration) rates in red light were 0.443‚ -0.141‚ and -1.1 ppm/g/min with a mean value of -0.27 ppm/g/min. The values of photosynthesis (plus respiration) rates in blue light were 2.449‚ 1.667‚ and 2.997 ppm/g/min with a mean value of 2.36 ppm/g/min. A t-test comparing the mean photosynthetic rates under red and blue light indicated no significant difference

In 1905‚ Frederick Blackman‚ a British physiologist‚ concluded that photosynthesis‚ the capture of light and conversion of it into chemical energy is a two-way process‚ of which only one uses direct light to trap radiant energy. In the Hill Reaction activity‚ our group will be focusing directly on the light dependent reaction. The overall purpose of this experiment is to try to prove the hypothesis that this reaction does produce compounds that have the energy of light. The first of the two major

Each chlorophyll molecule will travel up the paper at different rates. Hypothesis: If chlorophyll is removed from the plant‚ then the different pigments in the plant can be visible.
