NADPH from the light reactions. Unlike the light reactions‚ which take place in the thylakoid membrane‚ the reactions of the Calvin cycle take place in the stroma. In the Calvin cycle‚ getting pulled into the cells using RUBISCO to facilitate the process incorporated gaseous CO2 molecules. RUBISCO acts much like a sponge with a great absorptive power to suck up the CO2 from the air surrounding a plant. Photosynthesis is a process used by plants and other organisms to convert light energy‚ normally

Photosynthesis Experiment Introduction Photosynthesis is a process used by plants‚ making inorganic molecules into organic molecules (food) using sunlight. Carbon dioxide + Water (mainly from rain) Glucose + Oxygen From this process‚ carbon dioxide comes from environment. Glucose‚ as a product is used to make energy for growth. Lastly‚ the oxygen is a waste product in this chemical reaction‚ which become part of the Earth’s atmosphere. At this experiment‚ carbon dioxide and water

Photosynthesis Lab Report Introduction The lights are essential for photosynthesis and it plays a major role. All the food we eat and all the fossil fuel we use is a product of photosynthesis‚ which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems. Photosynthesis is carried out by many different organisms but usually by plants and algae. All these organisms convert CO2 (carbon dioxide)

Light Intensity Experiment: For the light intensity experiment‚ our first set of data illustrated strange correlations between the three tubes placed in front of a light source‚ so the data provided in e-campus was used. The tube that was 24 cm away from the light had the greatest decrease in absorbance over the course of 20 minutes‚ followed by the 30 cm and then the 49 cm light apparatus. The tube that was placed in the dark (wrapped in foil) remained a dark blueish-green color whereas the tubes

The Effect of Light Intensity The effect of different light wavelengths was tested in the following experiment. The rate of photosynthesis can be affected depending on the light treatment it receives. With the aid of DPIP acting as NADPH in photosynthesis‚ it was possible to observe the reaction as it took place. Samples were created with dark‚ 24 cm‚ 30 cm‚ and 49 cm light treatments. The absorbance was measured in five-minute intervals for each sample and recorded in an appropriate table

LIGHT IN PHOTOSYNTHESIS Theory: Leaf discs float normally. When the air spaces are infiltrated with the solution the overall density of the leaf disc increases and the disc sinks. The infiltration solution includes a small amount of sodium bicarbonate. The bicarbonate ions serve as the carbon source for photosynthesis. As photosynthesis proceeds oxygen is released into the interior of the leaf which changes the buoyancy – causing the discs to rise. Since cellular respiration is taking place

It is hypothesized that altering the amount of light received by duckweed will alter its photosynthetic rate. It is predicted that a lower light intensity will lower the rate of growth in duckweed. Two treatment groups were covered with a screen in order to reduce light intensity. Both groups were kept under a controlled light source for fourteen days and plant counts were taken at regular intervals. The

I will test this by exposing the pondweed to different wavelengths of light to see how it reacts. Method I will do this by passing white light through a filter. The filter will remove all unwanted wavelengths of light leaving the plant exposed to only the desired wavelength of light. I will use three different wavelengths of light 750nm

Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water
