    6‚ 2012 Photosynthesis Lab 1. Introduction: Light dependent reactions are the first phase of photosynthesis. It requires light to happen and happens in the thylakoid membrane in a chloroplast. The light energy is absorbed from the sun and converted into chemical energy. Which is then stored temporarily in ATP and NADPH. Hypothesis: I predict that the wavelength intensity will affect the rate of photosynthesis more than light intensity will. 2. Data: # ATP | Light Intensity (Lux) | Time

    What Factors Affect the Rate of Photosynthesis in living leaves? Abstract: In this lab‚ four different types of leaves were tested to see the rate at which each leaf photosynthesized. This lab demonstrates how plants store light‚ capture light‚ and use light as energy for reproduction and growth‚ by photosynthesis. The control in this experiment was spinach‚ which was tested before any of the other plants were. The other plants that were tested were English Ivy‚ C4 Plant‚ and a multicolored

    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

    The effect of wavelength of light on the rate of photosynthesis was investigated in this experiment. The results from Figure 13 suggest that white light‚ containing all wavelengths of coloured light‚ has the highest rate of photosynthesis. Purple light had the second highest efficiency‚ followed by blue‚ red‚ and yellow light. Green light was significantly less efficient‚ producing the second lowest pH reading (Figure 14). The samples exposed to no light had the lowest rate of photosynthesis. The

After the leaves of the seed are exposed to lightphotosynthesis provides the seed with food and the food stores are no longer needed. In this research‚ the relationship between Mung bean light exposure and germination will be investigated. In order for germination to take place certain external factors are needed.
