gracilis have widely been applied as endpoints in assessing the toxicity of water pollutants like organic substances, toxic metals, detergents and wastewaters [2,5,6,54,66] .All green plants and algae absorb and utilize light with their pigments to run photosynthesis.

Photosynthesis and photosynthetic pigments in the flagellate Euglena gracilis - As sensitive endpoints for toxicity evaluation of liquid detergents

Investigating the light dependent reaction in photosynthesis

Do not use too much baking soda! Use just enough to barely cover the bottom of the film can. If you use too much, bubbling will occur. The resulting bubbles will stick to the leaf disks and keep them from sinking. Add a drop of liquid soap or detergent to the baking soda solution to reduce static. After you have created a vacuum in the syringe, some of the leaf disks may still float. This is frequently caused by bubbles stuck to the disks. These bubbles can usually be removed by sharply rapping the syringe on the edge of a desk or with your finger. While running your experiment, tap the syringe with your finger every 20-30 seconds to dislodge disks which are ready to float but stuck to the syringe. Remember that photosynthesis is dependent on light. For your initial experiments you may want to have the disks rise quickly (3-5 minutes). This will require that your syringes be several centimeters from the light source. This investigation can also allow you to explore respiration through the measurement of oxygen consumption. Respiration is common to all plants, animals and other organisms which live in an aerobic environment. When plants are grown in the light they usually produce more oxygen through photosynthesis than they consume through respiration. However, when plants are grown in the dark, the trapping of light by photosynthesis can no longer occur, and more oxygen is produced by photosynthesis. Thus, when the syringe in this experiment is put in a dark place, or covered by a black film can, it is possible to investigate plant respiration. White light is composed of all of the colors of the spectrum. You can investigate which of these colors are necessary for photosynthesis by covering the syringe with cylinders of different colors of plastic film. We suggest you try at least the three primary colors: red, yellow and blue.
