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 …

Alternatively, they could explore how to measure the rate of photosynthesis using various probes interfaced to computers. 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.

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

the time it takes for leaf disks to rise to the surface. As an extension you may propose that the floating disks be placed in the dark to determine if the disks will sink after photosynthesis ceases. After mastering the basic techniques in the controlled lab, each pair of students will design and carry out

In this lab, leaf disks will be used to assay the rate of photosynthesis under various light conditions. The leaf disks will be put into a solution of baking soda (sodium bicarbonate, NaHCO 3) and detergent. The baking soda is a source of carbon, and the detergent acts as a wetting agent that makes it easier for the

While this is going on, the leaf is also carrying out cellular respiration. This respiration will consume the oxygen that has accumulated and possibly cause the plant disks to sink. In other words, the buoyancy of the leaf disk is actually an indirect measurement of the NET rate of photosynthesis occurring in the leaf tissue. Pre-lab Questions: 1.

leaf disks. 9. How do floating disks correspond to the rate of photosynthesis? As photosynthesis occurs, oxygen is released. An accumulation of oxygen in the leaf disks will cause them to float. As photosynthetic rates increase, more oxygen will be released. The rate of photosynthesis should correlate with the intensity of the light provided. 10.

Light Reactions chain, it gets trapped in the inner spaces of the leaf So as photosynthesis takes place in the leaf disk, tiny oxygen bubbles will push out the solution from the leaf spaces and make the leaf disks light enough to rise.
