Lab # 1 Inverse Square Law Lab Lab Executed: September 13‚ 2012 By: Arfan Rehab Colleagues: Edwin Chen‚ Tamzid Hassan‚ and Tony Zhao Abstract: The objective of this experiment was to measure the relative intensities of light at various horizontal distances from the lamp. The light detector (photocell) will enable us to make light intensity measurements that are more precise than those made with the human eye. The photocell converts light intensity to an electrical potential

Photosynthesis is a process through which plants and some certain types of bacteria get energy from the sun’s UV-rays and use it to create and store sugar that is transformed into ATP by cellular respiration later on in the process. In plants‚ this process takes place in chloroplasts‚ which concentrate in the mesophyll cells‚ with the help of chlorophyll‚ the green pigment‚ which is directly involved in photosynthesis. It is important to understand that we see leaves green simply because the green

All green parts of a plant have chloroplasts. However‚ the leaves are the major site of photosynthesis for most plants. There are about half a million chloroplasts per square millimeter of leaf surface. The color of a leaf comes from chlorophyll‚ the green pigment in the chloroplasts. Chlorophyll plays an important role in the absorption of light energy during photosynthesis. Chloroplasts are found mainly in mesophyll cells forming the tissues in the interior of the leaf. O2 exits and CO2 enters
Premium Photosynthesis
Photosynthesis (pron.: /foʊtoʊˈsɪnθəsɪs/; from the Greek φώτο- [photo-]‚ "light‚" and σύνθεσις [synthesis]‚ "putting together"‚ "composition") is a process used by plants and other organisms to convert the light energy captured from the sun into chemical energy that can be used to fuel the organism’s activities. Photosynthesis occurs in plants‚ algae‚ and many species of bacteria‚ but not in archaea. Photosynthetic organisms are called photoautotrophs‚ since they can create their own food. In plants

SCIENTIFIC REPORT ON THE EFFECT OF WAVELENGTH ON PHOTOSYNTHESIS Red wavelengths will increase the rate of photosynthesis to a greater degree than blue or green wavelengths and thus will be the most optimal for plant growth. This hypothesis will be tested under laboratory conditions using silver beet extracts and DCPIP under different wavelengths and assessing the photosynthetic qualities using a spectrometer at 605nm. Photosynthesis is the process by which the suns visible light (electromagnetic

This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating
