4. A potometer is used to measure water uptake by a cut shoot of a plant. The data shows the mean rate of water uptake by cut shoots of the same plant for 10 minutes. Four environmental conditions were tested, with 6 repeats at each. The first measurement was discarded and the mean of the following 5 measurements was recorded in the table. The temperature, light intensity and humidity were monitored 10 times during each measurement of water uptake and their mean values recorded in the table.
