Limp spinach will not undergo photosynthesis. 2. Loosely fill the blender with the light-primed spinach until it is about ¾ full. Pour 0.5 M cold sucrose into the blender cup until the blender cup is about ½ full with liquid. 3. Blend the spinach with three short bursts of 10 seconds each. 4. Pour the blended mixture through a double layer of ...

Reflected/transmitted light energy is generally not available to photosynthesis. It is the absorbed light energy that can do useful work in photosynthesis. In the first part of this laboratory you will prepare a pigment extract from the chloroplasts of spinach leaves.

As photosynthesis proceeds, the disks will start to float. At 2 minute intervals, invert the syringes to agitate the leaf disks and immediately return them to their positions in front of the lights. Count the number of disks floating after each interval until all disks are floating. ... young spinach leaves. 50 mL beaker for sodium bicarbonate ...

6. Set up and run the spinach oxygen production measurements. 7. Set up and run the manometer experiment (effect of wavelength on Ps) A. Photosynthetic “Photography” As pointed out above, in the light dependent reactions of photosynthesis, photon energy is absorbed by pigment molecules and transferred to a reactive chlorophyll a molecule.

The energy to drive the chemical reactions of photosynthesis comes from the sunlight absorbed by the chlorophyll molecules. Hence, the first step in photosynthesis is the absorption of visible light from the sun by chlorophyll molecules. The chlorophyll molecules then transfer the light energy to chloroplasts, the reaction center of photosynthesis.

Photosynthesis may be studied in a number of ways. For this experiment, a dye-reduction technique will be used. The dye-reduction experiment tests the hypothesis that light and chloroplasts are required for the light reactions to occur. ... Use a coin to extract the pigments from spinach leaf cells. Place a small section of leaf on the top of ...

Imagine you actually completed the Section 4-1 of the Photosynthesis Lab, the Chromatography portion. Assume that the chromatogram drawn below is what you obtained after transferring the pigment onto the chromatography paper from a spinach leaf using a coin. Complete the following chart: What is the solvent front for the chromatogram drawn?
