as the carbon source for photosynthesis. As photosynthesis proceeds oxygen is released into the interior of the leaf, which changes the buoyancy--causing the disks to rise. Since cellular respiration is taking place at the same time, consuming oxygen, the rate that the disks rise is an indirect measurement of the net rate of photosynthesis.

The central vacuole, shown in the center, stores the product of photosynthesis: sugar (in various forms like starch). u This lab focuses on several different factors that affect the net rate of photosynthesis. We will be comparing the rate of photosynthesis in different light intensities -including in the dark- by

The higher temperature had a rate of - 0.044447 ppm/s. The hypothesis was supported because the plants had a faster rate of photosynthesis at the lower temperature. Introduction The purpose of this experiment was to test whether or not raising the temperature in an environment would effect the rate of photosynthesis. In the process of

This lab examines photosynthesis using an inquiry approach. Should be placed after basic concepts of photosynthesis have been covered. This lab examines how light intensity (a variable) affects the rate of photosynthesis and demonstrates that photosynthesis is a measurable process. Background: Knowledge - Photosynthesis

Jan 31, 2014 · Changing the amount of CO2 a plant receives impact the rate of photosynthesis because if there is an increase of the carbon dioxide concentration, then the rate of photosynthesis will go up. Changing the amount of light a plant receives impact the rate of photosynthesis because the brighter the light gets, the rate of photosynthesis increases.
