the process). Scientists interested in measuring the rate of photosynthesis have . two potential avenues: they can measure how much CO2 is taken up by the plant or . they can measure how much O2 is released from the plant. In the third and final . part of this laboratory we will determine the effect of light wavelength on the . photosynthetic rate.

Photosynthesis. Objectives. At the completion of this laboratory you should be able to: * Describe how light intensity, light wavelength, and temperature can affect photosynthesis. * Design an experiment to measure how light intensity, light wavelength, and temperature can affect photosynthetic rates.

The effect of light colour and intensity on the rate of photosynthesis. 1. ... A convenient way to investigate the effect of light colour on the rate of photosynthesis is to place a filter between the light source and the sample and an experimental set-up, using a blue filter, is shown schematically below. ... Wavelength (nm) Absorbance ...

photosynthesis, plants use the energy of light to produce . glucose (C. 6 H 12 O 6) from carbon dioxide (CO. 2), and water (H 2. O). Glucose is a simple sugar that plants use for energy and as a building block for larger molecules. A by-product of photosynthesis is oxygen. Plants use some of the oxygen they produce, but most of it is released ...
