Photosynthesis nourishes almost all of the living world directly or indirectly(Campbell 1993). It is the process used by certain organisms to trap light energy and convert it to chemical bond energy, forming organic compounds (Vliet 1993). Chloroplasts are the sites of photosynthesis. All of the green parts of a plant have chloroplasts, but the leaves are the major site of photosynthesis (Campbell 1993). Chloroplasts are made up of four major internal membranes. They are arranged in layers …showed first 75 words of 747 total…

We repeated this procedure until all wavelength and intensity values were tested. Results When all of our experiments were finished all of the data was collected and scored in the following tables. Tables one thru four are the data we complied. Table 1: The absobance of the cells at different wavelengths over 14 minutes.
