6. Why did the disks sink in the dark? (Cellular Respiration)

If the solution is too dilute, the lack of CO2cap C cap O sub 2 becomes a limiting factor. floating leaf disk photosynthesis lab answers

In this lab, we use a vacuum (created by a syringe) to replace those gases with a liquid bicarbonate solution. This makes the leaf disks sink. In this lab, we use a vacuum (created

Here are the standard comparisons usually performed in this lab and the scientific explanations for the results. As the leaf disks undergo photosynthesis, they produce

As the leaf disks undergo photosynthesis, they produce oxygen as a byproduct. The oxygen gets trapped in the air spaces within the leaf, causing the disk to become buoyant and float to the surface. The time it takes for the disks to float is inversely related to the rate of photosynthesis.
