In this lab you will be investigating the effects of different environmental factors on the rate of transpiration in a plant. You will be using a. potometer. (a pipette attached to a rubber tube) to measure the rate of water loss in a plant.n this lab you will be investigating the effects of different environmental factors on the rate of transpiration in a plant.
