The floating leaf disk assay for investigating photosynthesis brad williamson introduction: trying to find a good, quantitative procedure that students can use for exploring photosynthesis is a challenge the standard procedures such as counting oxygen bubbles generated by an elodea stem tend to not be “student” proof or reliable this is a particular. Floating leaf disk assay lab if a fluorescent light is covered in red cellophane, then photosynthesis will happen at the quickest rate, and leaf disks will float to the top of a baking soda solution quickly due to oxygen production. In the floating leaf disk procedure, a vacuum is used to remove trapped air and infiltrate the interior of plant (leaf) disk samples with a solution containing bicarbonate ions that serve as a carbon source for photosynthesis. The floating leaf disk assay for investigating photosynthesis brad williamson introduction: trying to find a good, quantitative procedure that students can use for exploring photosynthesis is a challenge.

the floating leaf disk assay for Investigating photosynthesis using a floating leaf disk assay introduction photosynthesis is the metabolic process used by all autotrophs to capture light energy and convert it to the chemical energy in carbohydrates.

Leaf disks float, normally when the air spaces are replaced with water the overall density of the leaf disk increases and the disk sinks.

Try the leaf disk assay, one of the easiest and best photosynthesis labs available students measure the rate of photosynthesis using leaf disks the equipment and supplies needed are inexpensive, simple, and readily available this activity is great for stimulating additional student projects. The floating leaf disk assay for investigating photosynthesis background: photosynthesis fuels ecosystems and replenishes the earth’s atmosphere with oxygen.

Leaf disk increases and the disk sinks the saturating solution should include a small amount of sodium bicarbonate of floating disks microsoft word - floating leaf disks for investigating photosynthesis v2 author.

  • Leaf disks into the syringe barrel replace the plunger being careful not to crush the leaf disks push on the plunger until only a small volume of air and leaf disk remain in the barrel ( 10%) • pull a small volume of sodium bicarbonate solution into the syringe tap the syringe to suspend the leaf disks in the solution.

The punched out leaf disks will initially sink in a test tube of water but will float as photosynthesis occurs students will write a lab report including, hypothesis, experimental design, data collection / analysis, and conclusion (findings. 14 minutes, the leaf disks were moved into the dark and the number of floating disks were recorded every minute below is a graphical representation of the data.
