Question

Bench: Photosynthesis Part H The floating disk technique londs itself to independent investigation as it is relatively simple to collect large amounts of data in a fairly short period of time. To build your skilat doing this, consider the following scenario A student decided to compare the rate of photosynthesis in English ivy leaves that were newly opened to leaves from the same plant that had been on the wine for many woes She punche out 10 disks from each leaf type, created a vacuum to remove the gases in the mesophy and sank them in 200 mL of a 0 2% sodium bicarbonate solution in plastic cups The cups were placed four inches from a fluorescent light source Every minute, the number of disks that had nsen in each solution was recorded this procedure was repeated with fresh disks for all of five trials Which metric would provide the most useful information for comparing the triale? the total time it takes 10 disks to rise in each trial the mean time it takes 10 disks to rise in each trial the median time it takes five disks to rise in each tral the mean time it takes five disks to rise in each trial Submit Request Answer

Answer 1

The most useful information for comparing the trials will be

the mean time it takes 10 disk to rise in each trial because the rate of photosynthesis is calculated by the number of leafs floating per unit time in the beaker..

Here, we can see the process of photosynthesis will lead to the production of oxygen which will get trapped in the mesophyll cells of the leaves and will enable them to float. so the number of leaves floating per unit time will give the rate of photosynthesis
