Transpiration is a process where water vapor is lost through any part of the plant. In order to conclude which plants transpire more, six plants were used to collect data on amounts of water vapor given off. The six plants used in this experiment are different in form and structure. The tomato plant not only can bear a fruit, but it also has a greater surface area which would allow more space for the water vapor to escape. These factors would most likely cause the tomato plant to transpire at a greater rate.
