Plants use photosynthesis to convert solar energy into chemical energy. The rate of photosynthesis can be determined indirectly by DPIP, which is a dye that essentially mimics coenzyme NADP, which becomes reduced when an electron is added to NADPH during light reactions (Lab...

...rmines what wavelengths of light can be absorbed. Plants that are green normally contain chlorophyll a as well as b. These chlorophylls, absorb different types of wavelengths, but don 't absorb ones that are green. These plants are green because that wavelength of light is reflected instead of absorbed. Different colors of light can affect how much photosynthesis occurs, because only certain colors are absorbed. The more color that’s absorbed, the more light that’s absorbed, which leads to more photosynthesis. Our experiment demonstrated that the red wavelength was the most effective for photosynthesis behind white, which was our positive control due to the fact that it contains all the colors of the spectrum. In our final experiment for the absorption spectrum our results supported our hypothesis and the absorbance levels decreased as we increased the wavelength.

- Investigating How Much Light Intensity Affects the Rate of Reaction Aim: To investigate how much light intensity affects the rate of reaction. Reaction: photosynthesis of Canadian pondweed (Elodea) Introduction- what is photosynthesis. The definition of photosynthesis is when plants process water and carbon dioxide to produce glucose by the process of photosynthesis. Photosynthesis is the method that plants use to make their own food. When photosynthesis takes place, plants use the suns energy to combine carbon dioxide from the air with water from the soil to create glucose (a carbohydrate).... [tags: Papers]

- The Effect of Light Intensity on the Rate of Photosynthesis Introduction Green plants don't exude food from the soil they make their own, using sunlight. This is called photosynthesis, which means "making through light". This occurs in the cells of a green plant, which are exposed to sunlight. Four things are needed to make this process work and this gives two thing: the four things needed are light from the sun, carbon dioxide diffuses from the air, water from the soil and chlorophyll in the leaves....

- The Effect of Light Intensity on the Rate of Photosynthesis Plan: Aim: To investigate the affect of light intensity on the rate of photosynthesis. Theory: Before I predict what will happen I must look at how photosynthesis occurs. Photosynthesis is the way plants create a source of food for themselves. Photosynthesis requires the following resources; Carbon Dioxide, Water and light. Inside the leaves of a plant there is a green substance, this substance is known as chlorophyll.... [tags: Papers]

- Investigating the effects of light intensity, NH4CL, and DCMU on the rate of electron transport in spinach thylakoid membranes was the purpose of this lab. Photosynthesis is the process that routinely drives electron transport across the thylakoid membrane but can be impacted when additional factors are added. Two phases known as Light reactions and the Calvin cycle makeup photosynthesis. Plastoquinone shuttle, water oxidation, and NADP+ reduction are the major factors of the light reactions. Photosynthesis creates a proton gradient when pigments in the thylakoid membrane absorbs light energy from the sun.... [tags: Photosynthesis, Cellular respiration]

- The Effect of Light Intensity and Temperature on the Rate of Photosynthesis Aim The aim of my experiment is to determine whether intensity of light and temperature would affect the rate of photosynthesis in a plant. To do this, I will place a piece of pondweed in varying light intensities and temperatures, and observe the amount of oxygen being given off. I am using pondweed because of its unusual quality of giving off bubbles of gas from a cut end, when placed in water. Introduction Photosynthesis occurs only in the presence of light, and takes place in the chloroplasts of green plant cells.... [tags: Papers]

- An Experiment to Investigate the Effect of Light Intensity on the Rate of Photosynthesis Introduction Photosynthetic takes place in the chloroplasts of green plant cells; it can produce simple sugars using carbon dioxide and water causing the release of sugar and oxygen. The chemical equation of photosynthesis is: [IMAGE]6CO2 + 6H20 C6 H12 O6 + 6O2 it has been proven many times that plants need light to be able to photosynthesize , so you can say that without light the plant would neither photosynthesize or survive....

- How concentration affects reaction rate. The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the solution will become yellow and will change from being transparent to translucent to opaque. The sulphur is formed as a solid but not in the usual precipitation way. Na2 + S2 + 2HCL 2NaCl+SO2 + S2 +H2O To time the reaction I will draw a black cross on a piece of plain paper on which the beaker of reactants will be placed (HCL and Thiosulphate)....

- Light Intensity's Effect on Photosynthesis Aim : To find out how light intensity will affect the rate of photosynthesis in a piece of Canadian Pondweed. Prediction : I predict that as I increase the distance between the light source and the Canadian Pondweed (reducing the light intensity), the volume of oxygen produced within the time limit (the measure of the rate of photosynthesis) will decrease. This will happen because as the light source is moved further away, less light rays will reach the surface of the Pondweed, shown by this diagram; [IMAGE] [IMAGE] [IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE] Light source [IMAGE][IMAGE...

- Lab Report Testing the Effect of Light Intensity on the Rate of Photosynthisis I'm going to investigate the amount of light used in photosynthisis to see if it has a noticable effect when you increase or decrease the light intensity. Photosynthisis is the way in which light and carbon-dioxide is used by a plant to produce energy in the form of starch. 6CO + 6H O = C H O + 6O The factors that effect the rate of photosynthisis are the amount of light, the amount of carbon-dioxide (CO ) and the temperature that can be used by the plant....
