The document summarizes an experiment that measured the rate of transpiration in different flower species by observing how quickly blue food coloring moved from the stem into the petals. It was hypothesized that larger flowers with greater circumference would transpire more slowly. However, the results found that smaller flowers like roses transpired more quickly, with blue coloring appearing after six hours compared to over thirty hours for spider mums. The conclusion is that different plant species can have varying rates of transpiration, with smaller circumference flowers transpiring faster than larger ones in this experiment.
