Absorption minima of the isolated chloroplasts was noted at a wavelength of 580 at an absorption of 0.291 (Fig 1.). This indicated that green light is reflected strongly by the spinach pigment. (Dansereau‚ 2013) Figure 1- Absorption spectrum of isolated chloroplasts from spinach . To test absorption of isolated chloroplasts from spinach when filters were added‚ filters were placed on cuvettes and time was taken in 3 minute intervals When there was no filter the absorption rose

Chapter I Introduction Photosynthesis is the process by which autotrophic organisms convert light energy to chemical energy in the form of glucose. Without this process life on earth would be very different because every organism directly or indirectly depends on photosynthesis. Photosynthesis helps the plants to grow roots‚ leaves‚ flowers and fruits. It is an extremely important process because plant tissue serves as the bottom of every food chain. The process of photosynthesis is dictated

Sociology 205 Professor Rogers January 29‚ 2013 Political Spectrum: Where I Fit In After carefully reviewing what it means to be a liberal or a conservative‚ I have found that I have mixed beliefs depending on what the issue is. With that being said‚ I still tend to find myself leaning a bit more to the left‚ than the right‚ making me fall into the 10.9% of the population who consider themselves to be slightly more liberal. What I like about the liberal point of view‚ is that they are accepting

There was no visible light out. It was calm out tonight; mid night dew still fresh on my boots. The smell of fresh pine covered the bare spot of the forest I was now camped in. It was time to break camp; camping too long in one spot could give away my posion. I quickly put away the rest of the salted pork in my left leg pocket and mounted my gun on my right shoulder. I started to stand up‚ but very slowly as to not alert a fly. I finally reach mid standing (not quite standing‚ but not quite crouching

Determining the concentration of red dye #40 in an unknown solution Introduction: White light is composed of many different wavelengths of light combined together. A spectrophotometer is an instrument that shines a single wavelength of light of a known intensity into a solution and then measures the intensity of the light exiting the solution. If a solution contains

1. What are some benefits of using halogen light bulbs in lighting fixtures for filming? – The benefits of using the halogen lights could be that they can last longer and are much brighter than regular light bulbs. 2. Describe in detail how to create the effect of light coming through a window onstage in a theatrical production. – A metal cutout will create an effect of a light shining through a window‚ so that it doesn’t look like a straight up spotlight on stage. 3. What is hard light? How does

In this experiment spinach‚ DPIP‚ phosphate solutions were placed under various filters and the percent orange light transmittance through the solution was measured to determine the rate of photosynthesis. This experiment was set up to discover how different wavelengths of light affect the rate of photosynthesis in a spinach‚ DPIP‚ phosphate solution. I proposed that the spinach‚ DPIP‚ phosphate solution under no filter‚ and therefore exposed to all light will have a highest percent orange light

Measuring the Effect of Light Intensity on Photosynthesis Introduction Photosynthesis captures energy from sunlight. Plants‚ algae‚ and some bacteria use the energy captured during photosynthesis for their metabolic reactions. During photosynthesis in plants‚ chlorophyll and enzymes in leaves convert certain wavelengths of light into chemical energy. A simple equation can be used to represent photosynthesis. Enzymes and Chlorophyll light energy CO2 H2O carbohydrate O2 In this investigation

Do men really pay attention to what girls wear? Do certain colors make them look more attractive? Research has been shown that men like when women wear the color red. They find it to be a hot color. Woman completed a survey online and they said that they will wear the color red for a romantic date. Scientist are not so sure on this theory. They don’t know if they can put all their evidence into some internet survey. A research took place where they invited woman to go to a lab and join the psychology

The overall experiment consisted of three smaller experiments as a result of the different properties chlorophylls possess and the need to test them individually to receive the most accurate results. Preparation for the lab began with selecting a medium to large spinach leaf and deveining it. Once the spinach was prepared‚ it was ground in 5 mL of 100% acetone‚ creating a green acetone extract. The extract was filtered through a funnel with a kimwipe and into a test tube. The volume of the filtered
