6. Why did the disks sink in the dark? (Cellular Respiration)
If the lamp is too close, it may "cook" the enzymes in the leaf tissue, denaturing them and stopping photosynthesis entirely. Conclusion
This guide is designed to help you understand the . It covers the "why" behind the procedures, explains the variables, and provides the typical results and conclusions you would expect in a formal lab report. floating leaf disk photosynthesis lab answers
If you are asked to calculate the rate, you can use: $$Rate = \frac1ET50$$ This converts the time into a "per minute" rate, making higher numbers indicate faster rates (which is more intuitive).
Leaf tissue is naturally buoyant because the spongy mesophyll layer is filled with gases (oxygen and CO2). Conclusion This guide is designed to help you
Generally, as light intensity increases, the ET50 decreases. This means photosynthesis happens faster because more photons are hitting the chlorophyll to power the light-dependent reactions. However, this eventually levels off when the system becomes "light-saturated."
If the exact 50% falls between time points, you can interpolate: Leaf tissue is naturally buoyant because the spongy
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 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.
