How does light intensity and carbon dioxide levels affect photosynthesis rate Phaladi Phaladi 201102379 Department Of Mathematics And Science Education University Of Botswana Plants‚ through the use of chlorophyll (green pigment in plants) that traps light can generate ‘food’ by combining carbon dioxide in the air and water. As with many chemical process energy is need to make and break molecules during the chemical process. The greater the light levels the more energy is available to carry

In conclusion‚ one can determine how photosynthesis is impacted by light intensity through the experimentation on ivy leaf disks in a bicarbonate solution. The function of the sodium bicarbonate in this experiment was to provide a sufficient amount of carbon dioxide (CO2) for the photosynthesis process to occur. Without CO2 or any of the other necessary reactants‚ glucose nor oxygen cannot be produced. The leaves rise and sink due to photosynthesis occurring in the plant cells. As the carbon from

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 radiation)

the wavelength of the light and the rate of photosynthesis and instead it starts relatively high then decreases and increases again. The colour red gives the highest rate of photosynthesis (89 bubbles per minute) with blue giving the second highest rate of photosynthesis (70 bubbles per minute)‚ and yellow giving the third highest rate of photosynthesis (64 bubbles per minute) and green with by far the least (44 bubbles per minute). Although‚ we can see no direct correlation between the rate of photosynthesis

Investigating the Effect of Light Wavelength on the Rate of Photosynthesis Method Take a 250cm3 beaker and fill it with distilled water. Use distilled water so there are no impurities to disrupt photosynthesis. Then take x cm’s of elodia and put it in the beaker. Cover the elodia with the large end of a funnel and the tip of the funnel cover with a test tube. Then direct a light onto this experiment. Measure the amount of bubbles that come from the elodia for x minutes. A prediction

The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to
