Floating disks photosynthesis experiment
WebIn short, the data from the experiment demonstrated that the rate of photosynthesis of leaf disks varied depending on the color of the light source. White light appeared to be the most efficient light source for photosynthesis in spinach leave cells. Table 1: Number of Floating Spinach Leaf Disks under different Colored Lights over Time WebAt any given point in this experiment, the number of floating leaf disks is an indirect measurement of the net rate of photosynthesis. In photosynthesis, plants use energy from the sun, water, and carbon …
